1, buy sewage treatment equipment. Sewage treatment equipment manufacturers will calculate the amount of sewage to be treated every day according to the type and scale of pig farms, so as to recommend the corresponding sewage treatment equipment to you. I believe this is professional, and the treated sewage can meet the corresponding sewage discharge standards.
2. For farms with a large amount of sewage, the sewage is mainly used for washing pig houses, and this part of sewage does not have to use very clean sewage. Therefore, aquaculture wastewater can buy reclaimed water reuse equipment, and the treated wastewater can meet the reclaimed water reuse standard, which is enough to wash the pigsty, but two aspects should be paid attention to.
(1) The equipment must meet the standards. Even if the pigsty is cleaned, the pollutants contained in it can easily make pigs infected with diseases and even infectious diseases. Therefore, for farmers who want to recycle sewage, they should be especially careful when buying reusable equipment.
(2) As for the tap water pipe, the pipe that can be reused with reclaimed water must be a toilet flushing pipe, which is separated from the catering pipe and does not cause backflow to each other, because the treated sewage is forbidden to drink. Not even a pig. If it's not a separate pipe, you still don't want such equipment.
3. For the third method, it should be a relatively large investment and more eco-friendly. In fact, pig farm sewage, mainly fecal sewage, contains a lot of substances, but these substances are just the raw materials for rural areas and many biogas production. Therefore, it is a relatively economical and reasonable scheme to build a large biogas digester in the farm to produce biogas, but it is a cost, and the biogas digester has obvious requirements for temperature and biogas digester size. It's simple for professionals, but more troublesome for laymen.
At present, manufacturers specializing in sewage treatment equipment can't make such a design. Specializing in biogas may be possible, you can consult, but I know that in this case, the investment will be relatively large. Some of the generated biogas equipment can be directly used, and some can buy biogas generators to supply power to the equipment in the farm.
Therefore, if it is only a small and medium-sized farm, it is recommended to buy Wohua aquaculture sewage treatment equipment, which is more worry-free and integrated, and the treated sewage can be directly discharged to ensure that it meets the corresponding discharge standards for sewage treatment.
