Problems solved by technology

[0008] With the development of the times, my country's aquaculture industry is increasingly developing in the direction of intensification and large-scale, which has brought about the fact that the old aquaculture sewage treatment process cannot keep up with the development of the situation, and cannot effectively and economically treat the aquaculture industry waste water from the process

Embodiment Construction

[0031] figure 1 Shown, is a kind of livestock and poultry breeding sewage treatment process, comprises the following steps:

[0032]1) Sewage pretreatment: the aquaculture sewage is collected by the channel and flows to the grid well by itself, after removing debris through the grid well, it flows to the pH adjustment tank by itself, and the effluent adjusted by the pH adjustment tank flows to the wastewater adjustment tank by itself, and passes through the wastewater adjustment tank Complete the adjustment of water quality and water volume, and then send the effluent to the air flotation tank; the effluent after removing scum in the air flotation tank flows to the intermediate pool for water volume adjustment;

[0033] 2) Sewage biochemical treatment: A2 / O2 internal circulation biological denitrification and phosphorus removal process combined with contact oxidation process; that is, the effluent in the intermediate pool enters the UASB anaerobic pool from the bottom, and flo...

Abstract

The invention discloses a waste water treatment technology for livestock breeding. The waste water treatment technology comprises the following steps: 1) pretreating the waste water; 2) biochemically treating the waste water; 3) posttreating the waste water, wherein the pretreatment of the waste water mainly comprises a grating well, a pH regulating tank, a regulating tank, floatation equipment and a middle water tank; the waste water biochemical treatment mainly comprises an anaerobic tank, an anoxia and aerobic tank, an aerobic tank, a secondary sedimentation tank, and a contact aeration tank; the waste water posttreatment mainly comprises a coagulating sedimentation tank, a fiber filter disc and a disinfection drain tank. The waste water treatment technology can efficiently and conveniently perform purification treatment on the waste water, effectively reduce the manufacturing cost for the waste water purification treatment industry, and increase the production efficiency through the reasonable wastewater treatment process procedure arrangement.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a livestock and poultry breeding sewage treatment process. Background technique [0002] At present, aquaculture sewage contains a large amount of ring-chain organic compounds (high concentration COD), azide inorganic compounds (uric acid), ammonia nitrogen, suspended solids, etc. Whether these substances enter the water body (such as discharged into the surface water body or infiltrated into the ground water body), Or if some of them are released into the atmosphere, they will directly or indirectly cause serious harm to animals and plants and destroy the ecological environment. People who directly consume water containing certain concentrations of such substances, or inhale air containing such substances for a long time, will get sick and in severe cases can cause cancer; especially some substances can be enriched in animals or plants to concentrate their concentration...
