Problems solved by technology

However, most of the existing technologies use a longer biochemical residence time, use nitrification liquid backflow and add some carbon sources for denitrification, and the construction cost and operation cost are relatively high.
The current pig wastewater treatment system has low treatment efficiency, complex structure, and insufficient room for adjustment during operation. It often fails to cope with sudden pollution impact loads and external conditions such as temperature changes, and cannot discharge stably.

Abstract

The invention relates to a pig raising wastewater treatment process and system, and belongs to the technical field of livestock and poultry breeding wastewater treatment. The treatment process comprises the following steps: sequentially treating the wastewater by adopting an anaerobic baffled reactor and a sectional water inlet anoxic and aerobic process; the treatment system comprises the anaerobic baffled reactor and a sectional water inlet anoxic and aerobic treatment tank, wherein the anaerobic baffled reactor is communicated with the sectional water inlet anoxic and aerobic treatment tank, and the wastewater sequentially flows through the anaerobic baffled reactor and the sectional water inlet anoxic and aerobic treatment tank to be treated. The anaerobic baffled reactor, the high-load activated sludge process and the sectional water inlet anoxic-aerobic synergistic arrangement form the unification of the functions and the pool body structure, thereby being beneficial to reducingthe occupied area, optimizing the basic investment, enhancing the operation stability and lowering the operation cost.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding wastewater treatment, and relates to a pig raising wastewater treatment process and system. Background technique [0002] The biggest feature of pig wastewater is the high concentration of organic matter and ammonia nitrogen, and the large fluctuations in water quality. The difficulty in its treatment lies in the removal of organic matter and efficient denitrification. At present, most swine wastewater is anaerobically treated to form biogas slurry, and the biogas slurry is returned to the field for treatment. However, limited by the site, in many cases there is not enough land to absorb the biogas slurry, so it must be considered to discharge the biogas slurry after further treatment. For biogas slurry, the overall carbon and nitrogen ratio is relatively low, and the most difficult point is denitrification. However, most of the existing technologies use longer biochemical...
