Embodiment 1

[0042] Treatment of farm sewage with 10,000 broiler chickens in breeding scale:

[0043] S1: Flow the sewage to the filter tank, use stainless steel 20-mesh, 40-mesh and 60-mesh filter screens at the water inlet, middle and outlet of the filter tank to filter, step by step filtration can fully remove the filter residue in the sewage, and get filtered treated water. The filtered residue can be used as crop fertilizer after being dried and pulverized, reducing the planting cost of farmers.

[0044] S2: Put 10 parts of nitrifying bacteria, 20 parts of photosynthetic bacteria, 20 parts of Bacillus subtilis, 10 parts of lactic acid bacteria, 10 parts of yeast, 5 parts of actinomycetes, 5 parts of Bdellovibrio, and 10 parts of EM bacteria into the filtered water , 5 parts of cellobiose-producing Clostridium, 2 parts of mutual oxygen bacteria, reacted for 3 days to obtain purified water. In this step, a variety of microorganisms are used to work together, which can be mutually bene...

[0051] Treatment of farm sewage with 5,000 pigs in breeding scale:

[0052] S1: Flow the sewage to the filter tank, use stainless steel 20-mesh, 40-mesh and 60-mesh filter screens at the water inlet, middle and outlet of the filter tank to filter, step by step filtration can fully remove the filter residue in the sewage, and get filtered treated water. The filtered residue can be used as crop fertilizer after being dried and pulverized, reducing the planting cost of farmers.

[0053] S2: Put 10 parts of nitrifying bacteria, 20 parts of photosynthetic bacteria, 20 parts of Bacillus subtilis, 10 parts of lactic acid bacteria, 10 parts of yeast, 5 parts of actinomycetes, 5 parts of Bdellovibrio, and 10 parts of EM bacteria into the filtered water , 5 parts of cellobiose-producing Clostridium, 2 parts of mutual oxygen bacteria, reacted for 4 days to obtain purified water. In this step, a variety of microorganisms are used to work together, which can be mutually beneficial in the...

Embodiment 3

[0060] Treatment of farm sewage with 300 beef cattle in breeding scale:

[0061] S1: Flow the sewage to the filter tank, use stainless steel 20-mesh, 40-mesh and 60-mesh filter screens at the water inlet, middle and outlet of the filter tank to filter, step by step filtration can fully remove the filter residue in the sewage, and get filtered treated water. The filtered residue can be used as crop fertilizer after being dried and pulverized, reducing the planting cost of farmers.

[0062] S2: Put 10 parts of nitrifying bacteria, 20 parts of photosynthetic bacteria, 30 parts of Bacillus subtilis, 10 parts of lactic acid bacteria, 15 parts of yeast, 5 parts of actinomycetes, 5 parts of Bdellovibrio, 15 parts of EM bacteria into the filtered water , 5 parts of cellobiose-producing Clostridium, 3 parts of mutual oxygen bacteria, reacted for 5 days to obtain purified water. In this step, a variety of microorganisms are used to work together, which can be mutually beneficial in th...

Abstract

The invention discloses a cold region livestock and poultry breeding sewage treatment method. The cold region livestock and poultry breeding sewage treatment method comprises following steps: S1, sewage is delivered through a filtering basin, wherein filtering is carried out at a water inlet, a middle part, and a water outlet of the filtering basin using a filter screen; S2, after filtering, low temperature decomposition microorganism colonies are added into water for 3 to 5 days of reaction; S3, the processed water is subjected to coagulation, deposition, and filtering treatment; S4, after coagulation and filtering treatment, the water is delivered into an ozone reaction device, ozone is added for 4 to 5min of ozonization; S5, after ozonization, the processed water is delivered into a biological contact oxidation pond for 0.5 to 1h of biological contact oxidation; and S6, the water processed via biological contact oxidation is delivered into an anaerobic pond, is heated to 15 to 20 DEG C with solar energy, low temperature decomposition microorganism colonies are added at the same time, and the water is subjected to reaction for 5 to 7 days; and S7, disinfection is carried out using an ultraviolet ray sterilizer so as to obtain water for up-to-standard discharge. The cold region livestock and poultry breeding sewage treatment method is simple, is high in efficiency and low in cost, and is capable of solving water pollution problems caused by livestock and poultry breeding.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically, to a method for treating livestock and poultry breeding sewage in cold regions. Background technique [0002] The livestock and poultry breeding sewage mainly includes the urine excreted by livestock and poultry, the washing water of pens, feeding troughs, ground cleaning, equipment cleaning, etc., and a small amount of wastewater generated in the living and production process of workers. The aquaculture sewage is directly discharged into ditches or open waters without harmless treatment. Due to the rich content of nitrogen (N) and phosphorus (P) in these sewage, it is easy to cause eutrophication pollution of water bodies. High concentrations of sewage were discharged into the river, causing the water quality to continue to deteriorate. Sewage has a great impact on the production and life of surrounding farmers, and some have caused serious harm to the surroundin...
