Problems solved by technology

[0005] The existing sewage treatment scheme has the following deficiencies: on the one hand, special personnel are required to be responsible for the operation of the entire system during the treatment process, including adjusting the inflow and outflow of water, adjusting the amount of aeration, dosing, abnormal handling, etc., the lack of professional personnel, It is difficult for professional operation personnel to meet actual needs, and the increase in labor costs will lead to a significant increase in the operating costs of sewage treatment; secondly, due to the uncertainty of manpower, it is difficult to guarantee the effect of sewage treatment and the treatment efficiency is low

The system comprises an adjusting tank, a coagulating sedimentation tank, a UASB reactor, a primary denitrification reaction tank, a primary nitrification reaction tank, a primary sedimentation tank, a short-cut nitrification-denitrification device,a secondary sedimentation tank and a water discharge tank which are sequentially connected through a water conveying pipeline, and also comprises a PLC system used for controlling the sewage treatment process, a gas conveying pipeline used for conveying gas, and a sludge conveying pipeline used for conveying sludge. An artificial intelligence management mode is adopted, the intelligent level is high, the automation degree is high, the sewage treatment efficiency is high, the treatment effect is good, and energy conservation and environmental protection are facilitated.

Description

technical field [0001] The invention relates to the field of sewage treatment in pig farms, in particular to an unattended breeding sewage treatment system. Background technique [0002] With the improvement of people's living standards, the scale of the pig breeding market continues to expand. Since the beginning of this year, the price of pork has remained high. The main reason is the spread of swine fever. One of the reasons for the occurrence of swine fever is improper or incomplete disposal of pig excrement in pig farms. . [0003] Sewage from pig farms mainly includes pig urine, some pig manure, flushing water from pig houses, sanitary equipment in the factory area, and sewage discharged from public buildings. The concentration of organic matter is high, the content of ammonia nitrogen is high, and COD is generally 6000-7000mg / L; c. Wastewater has good biodegradability, fast hydrolysis, acidification, and good sedimentation performance; d. Sewage is often accompanied ...
