Questions and answers on the use of biological treatment equipment and chemicals for farm sewage

1 Q (q): how to determine the amount of sewage tank used?

Answer (a): for the first time, according to the amount of water, 1 package of this product is used every 1000 cubic meters of sewage per day (after activation, it is used for more than 24 hours, the same below). The sewage pool is only black and has a peculiar smell in the water. It splashes about seven days a day. After that, it is added at the inlet and outlet of biogas digester every day. If the pool becomes muddy and stinky, the whole pool will splash every day. The biogas digester is then added to the biogas tank's outlet for about 15 days a day. As long as new sewage enters, it needs to be continuously added.
 

  2 Q: How to calculate the required settling tank area after the biogas digester is exported?

   A: : take 100 cubic meters of sewage into the biogas digester as an example. After the biogas digester is exported, there are generally three sedimentation tanks, each with an area of no less than 5 mu. It was treated with biological treatment agent of farm sewage for about 10 days. Bamboo raft was used in the middle of each sedimentation tank. Aquatic plants were planted in the second half of the pond for plant filtration.
 

  3 Q: Can the sewage tank meet several water standards after treatment?

   A: : it depends on the situation. If there are new pollutants entering and there are enough sedimentation tanks and aquatic plants to filter, the standard of 3-5 kinds of water can only be met. The water quality of common fish ponds is this standard. If you want to meet the level 2 water standard, you need to add sedimentation and chemical treatment equipment at the end of the sedimentation tank.
 

  4. Q How to determine the time for fish culture with biological treatment agents for farm sewage?

   A (a) It was found that the smell of the lagoon was basically eliminated, the water quality turned dark red, the aquatic plants could not wither and die, and the experimental fish could be released. Generally speaking, the first and second sedimentation tanks are filled with hypoxia resistant fish (e.g. Egyptian pond hornfish) without the death of aquatic plants, and the final sedimentation tanks can be cultivated, such as tilapia, squid and carp. Fish, etc., the last tank can be installed with an aerator. At an average daily temperature of 25 ° C, it usually takes about 15 days for a black and foul smelling sewage pond to reach a basic odourless crimson color, which can be put into the standard for aquatic plants.

  5 Q How long does it take to remove the odor with a farm sewage biological treatment agent?

   A (a) : if the water is black and smelly when the daily average temperature is 25 ° C, for example, the odor will rapidly decrease after three days of continuous use, and the suspended solids in the tank will be pushed out by the sewage pool. In about 10 days, the odor decreased significantly.
 

  6 Q: How long does the septic tank stink after fish farming? Do you need to use farm sewage biological treatment agent frequently?

   A (a) : the sewage pool can be improved after treatment, as long as no new pollutants enter, it is an ordinary fish pond. The use of farm sewage biological treatment agents is no longer required; however, if there are often new pollutants (animal manure) when urine enters, the farm sewage biological treatment agent must be used continuously.
 

  7 Q: Can the wastewater from the farm sewage biological treatment agent meet the environmental protection requirements?

   A (a) : this depends on the environmental requirements of the pond, which are several types of water. Our products and technologies can only make your farm sewage smell tasteless and can improve the quality of fish. Generally speaking, without smell, the water quality of fish can be similar to that of farmland irrigation. It will not be punished. If you are a very large farm, remote monitoring through environmental protection, in order to get better water quality, you need to add in the back end Purification equipment And chemicals.
 

  8. Q: What should I pay attention to in low temperature season?

   A (a) : in low temperature season, microbial treatment of feces and aquatic plants will be reduced. There are only the following items: 1. Adding probiotics to feed can reduce the pollution of animal feces; 2. Adopting dry decontamination method to reduce flushing and save water to reduce sewage, because it is not necessary to clean the barn every day in low temperature season; 3. Adding a large amount of farm sewage biological treatment agent at the entrance of biogas digester, because the temperature of the biogas digester is high, most of the sewage is treated in the biogas digester; The deeper the pond is, the higher the water temperature will be, and the higher the water temperature will be.
