Chapter 618: Unable To Meet The Daily Feeding Requirement Of Forty Pounds? [Please Subscribe, Please
"After the biogas digester is built, materials must be fed and discharged frequently."
“For example, a biogas digester with an area of eight cubic meters, if possible, is recommended to be able to feed 40 pounds of fresh human, livestock and poultry manure, or perishable domestic waste and other biogas raw materials every day.
"As much material is fed in as much material is discharged, large discharges are prohibited to avoid affecting biogas production."
"At the same time, daily stirring should be strengthened. You can use a slag extraction piston or a wooden rod to stir the liquid for more than a quarter of an hour every day, so as to promote fermentation and increase the gas production rate."
"In addition, you should always observe the changes in the glazed water pressure column outside the biogas tank. When the value of the glazed water pressure column reaches more than nine."
"Then you should pay attention to using biogas in time, or deflating it in time to avoid excessive pressure inside the biogas tank, thereby damaging the glass water pressure column and the tank body.
"It is also necessary to frequently check whether each pipe joint, pipe, and appliance is sealed, damaged, aged, blocked, etc. If any problem is found, it must be repaired in time."
Yan Changqing looked at the governor of Haizhou City, a group of local officials in Haizhou City, as well as the old dean of the former academy and a group of academy students, and told them some precautions for the daily safe operation and maintenance of the biogas pool.
Hearing Yan Changqing's instructions, Haizhou City Zhizhou's eyes widened with a look of astonishment, and then he said with a helpless smile:
"Forty pounds of fresh human, livestock and poultry excrement, or perishable household waste every day, is this too high a requirement for ordinary people?!!"
"Even if there are five people in a family, each person can poop half a kilogram of feces every day, and they can only poop two and a half pounds of feces every day!!!"
"Even if poultry manure is added in, a family of five can produce up to about five kilograms of manure a day!!!"
"In the end, even if perishable domestic waste is added, the maximum production of biogas raw materials is about ten kilograms a day!!!"
"This is still a full thirty kilograms short of the forty kilograms of manure per day mentioned by Saint, or the forty kilograms of biogas raw material per day!!!"
"Even if the common people want to produce so much biogas raw material, there is nothing they can do!!!"
The princes Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes on the side couldn't help but nodded in agreement when they heard the words of the governor of Haizhou City.
Forty kilograms of manure a day, or forty kilograms of biogas raw material, is really too high for an ordinary family.
Even if ordinary people pull out their intestines, I'm afraid they won't be able to collect the weight of forty kilograms!!!
Yan Changqing looked at Haizhou City Zhizhou, shook his head slightly and said:
"You misunderstood me."
"First, what I just said is an eight-cubic-size biogas digester."
"In other words, if the biogas tank is smaller than eight cubic meters, the recommended daily amount of biogas raw materials can be appropriately reduced."
"For example, if it is a six cubic meter biogas digester, then the recommended amount of biogas raw material that needs to be fed every day can be appropriately reduced to 90 to 80 percent.
“In other words, if it is a six-cubic-size biogas digester, then the recommended amount of biogas raw material that needs to be fed every day is only thirty-six to thirty-two kilograms. 11
"Second, what I just said is 'if conditions permit', it is recommended that you should be able to consume forty pounds of fresh human, livestock and poultry manure, or perishable household waste every day to use as biogas. raw material'.
"In other words, this magnitude is not fixed.
"It can be more or less."
"The amount of biogas raw materials that are imported every day only affects the amount of biogas produced."
"Thirdly, for ordinary people, there are actually ways to produce 40 pounds of biogas raw material per day, and there are two ways!!!"
Having said this, Yan Changqing paused.
Prince Zhu Biao on the side couldn't help but ask:
"What method?!!"
Yan Changqing glanced at Prince Zhu Biao and then said:
"The first way is to collect the night incense produced by the people in the city!!!"
In the current era, there is no convenient and complete drainage system and flushing system like Yan Changqing's previous life.
Therefore, people in the city in this era generally used wooden barrels to carry their toilet.
And once it's full, it must be disposed of.
Generally speaking, people in the city will put buckets filled with excrement outside their back doors.
Then, from late at night to early in the morning, there will be a special night scent woman to collect them and dispose of them.
And these night fragrance women who are responsible for collecting and disposing of night fragrance are actually rural women from poor families.
These rural women transport the night incense produced by the people in the city and pour it into the methane digesters in their homes.
It can not only solve the problem of night fragrance produced by the people in the city, but also meet the demand of 40 kilograms of biogas raw materials for one's own home a day!
You can even earn some money to help support your family by helping people in the city collect and dispose of night fragrance!!
It can be said that it kills three birds with one stone!!!
According to the current situation, a small state city has a permanent population of more than 100,000, and a large city has a permanent population of more than 500,000 people. And based on the calculation that the common people in these state cities produce half a catty of feces per person per day.
Then a state city can produce about five to twenty-five cubic meters of excrement.
And if fifty thousand catties to two hundred and fifty thousand catties are divided by forty, then it is one thousand two hundred and fifty to six thousand two hundred and fifty.
In other words, the amount of feces produced by the people in these prefectures and cities alone in one day is enough to meet the needs of 1,250 to 6,250 biogas digesters, with a daily feed requirement of 40 kilograms!!!
In other words, it is enough to meet the feed needs of biogas digesters for rural households ranging from 1,250 to 6,250 households!!!
If we include the biogas raw materials produced by the rural people themselves, then the number of biogas digesters that can be satisfied will be even greater!!!
Therefore, by rationally utilizing the unnecessary night fragrance produced by the people in the city, it is barely possible to meet the needs of the rural people for feeding ten or forty biogas tanks.
Even if it does not reach the amount of 40 kilograms of feed, it will not be too different.
Everyone present was not ignorant of people's livelihood matters. When Yan Changqing said, "Collect the night fragrance produced by the people in the city," they all understood the meaning of Yan Changqing's words.
And I have to say that this is indeed a very good solution.
However, Chu King Zhu Zhen suddenly discovered a blind spot and asked:
"What if the people in the city also build biogas digesters?!!"
"Then they can keep the night incense for their own use and no longer need to pour the night incense?!!"
"In this case, the people in the countryside will not be able to collect the night fragrance from the people in the city, and the biogas digesters of the people in the countryside will be short of feed again?!"
As Chu King Zhu Zhen finished speaking, the eyes of everyone present focused on Yan Changqing again.
Because the possibility mentioned by Chu King Zhu Zhen does exist.
If this situation really occurs, how to solve it?!!
Is it necessary to use the second solution that has not yet been mentioned?!!
Thinking of this, everyone present was looking forward to Yan Changqing's answer.
However, Yan Changqing did not immediately say the second solution. Instead, he shook his head and explained to Chu King Zhu Zhen's question:
"."First of all, you need to know the positioning of biogas pools. It is a supplement to the way people at the bottom burn fires.
"And this kind of supplementary biogas energy is limited, short-lived, and even unstable."
"This limited, short-lived, and even unstable way of burning fires may be very precious to the people at the bottom who are extremely lacking in combustion energy."
"But for the people in the city who do not lack combustion energy, or who can continuously purchase enough firewood for use by spending money.
"This limited, short-lived, and even unstable method of burning fires is not worthy of their choice."
"To put it bluntly, people who can live in the city do not lack the money to buy firewood.
"And the people who lack money to buy firewood cannot live in the city for a long time."
"So from this perspective, people living in the city will basically not build biogas digesters for the limited, short-lived, or even unstable combustion energy of biogas.
"
"Secondly, biogas digesters cannot be built casually. It requires a medium-sized area that is suitable for building biogas digesters."
“In rural homes, every household generally has a large front and back yard, so there is no problem in building a biogas digester.
"But if you want to buy a mansion in the city that is not small in size and has a suitable place to build a biogas digester, it is not something that ordinary people can afford. (Zhao)" You must know that the mansion in the city The price of land is much more expensive than the price of academic land in the countryside.
"And people who can afford big houses in the city can't afford to build biogas digesters in their homes just to save money on firewood."
"Because if they really do this, then they will never even think about raising their heads in front of other people of the same status in the city!!!"
"To put it bluntly, for people with small houses in the city, even if they want to build a biogas digester, they don't have any extra space to build a biogas digester!!!"
"For people with large houses in the city, even if they want to build a biogas digester, they can't afford to lose face and build a biogas digester!!!"
"Therefore, based on these two reasons, the people in the city will basically not build biogas digesters."
"Naturally, the night fragrance produced by the people in the city will not be kept for their own use, but will continue to be handed over to the night fragrance women in the countryside for recycling and disposal!!!"
Hearing this, the doubt in the eyes of Chu King Zhu Zhen disappeared.
Everyone present also had no doubts about the first solution mentioned by Yan Changqing.
