High-efficiency livestock breeding water treatment system

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a high-efficiency livestock breeding water treatment system. The high-efficiency livestock breeding watertreatment system comprises a precipitating chamber, an anaerobic reaction chamber, a aerobic reaction chamber and a purifying chamber which are sequentially communicated with one another; a first operation port is formed in the top of the precipitating chamber, a water inlet pipe is communicated with the upper end of the side wall of the precipitating chamber, a filter screen is arranged at the upper end of the interior of the precipitating chamber, and a sludge chamber is arranged on the outer side of the precipitating chamber; and the precipitating chamber and the anaerobic reaction chamberare communicated with each other through a first water passing pipe, a second water passing pipe and a third water passing pipe are communicated with the position between the anaerobic reaction chamber and the aerobic reaction chamber, and the aerobic reaction chamber is communicated with the purifying chamber through a fourth water passing pipe. The treatment system conducts multi-stage treatmentsuch as precipitating, anaerobic treatment, aerobic treatment and disinfection and purifying on livestock breeding sewage, so that the breeding sewage is guaranteed to be purified cleanly, in the meantime, each stage can be subjected to cyclic backflowing and repeatable treatment, and therefore the treatment quality of the water treatment system is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a high-efficiency livestock breeding water treatment system. Background technique [0002] The factory-like and large-scale operation of animal husbandry has become an inevitable trend of production methods at home and abroad. This year, large-scale livestock farms in my country have developed rapidly and their scale has become larger and larger. At the same time, with the enhancement of people's awareness of environmental protection, the excrement produced in the production process of this factory-like animal husbandry industry has brought huge management pressure to enterprises on the one hand, and has also brought serious threats and damage to the environment. Animal husbandry wastewater is high-concentration organic wastewater rich in a large number of pathogens. It is directly discharged into the water body or stored in an inappropriate place. It may be washed into ...

AI Technical Summary

Problems solved by technology

[0003] Based on the above reasons, some sewage treatment methods and devices have appeared on the market, but these sewage treatment equipment usually only perform simple solid-liquid separation, and then manually remove the sediment, which is not only labor-intensive but also gives feedback on the use effect. The result is also very unsatisfactory. The discharged livestock sewage still contains a lot of impurities, and the content of bacteria is high, which cannot fully meet the requirements of sewage purification treatment.
