Livestock and poultry breeding sewage treatment agent and application thereof

Abstract

The invention provides a livestock and poultry breeding sewage treatment agent and application thereof. The livestock and poultry breeding sewage treatment agent is prepared by mixing microbial flora,mineral filler, magnesium salt, phosphate, organic fertilizer and humus, and the microbial flora is prepared from sphingobacterium S-4, bacillus gibsonii S-2, rhodococcus R-03, rhodobacter sphaeroides R-06 and paenibacillus polymyxa EBL-06. The livestock and poultry breeding sewage treatment agent is used for treating livestock and poultry breeding sewage to obtain a nutrient solution capable ofbeing reutilized. While livestock and poultry breeding sewage is treated, original sewage has biological activity, and stabilization, harmlessness and high-added-value recycling of the livestock and poultry breeding sewage are achieved. The obtained nutrient solution meets the safety index, the effectiveness index and the requirements of part of typical plant pathogenic microorganism antagonism experiments, can be widely applied to plant cultivation and crop planting, enables plants to be more luxuriant, green and robust, facilitates sustainable utilization of soil, and enables the soil to besoft and good in air permeability.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding, in particular to a livestock and poultry breeding sewage treatment agent and its application. Background technique [0002] With the development of the economy and the improvement of people's living standards, the demand for poultry meat products is also increasing, and the poultry breeding industry is promoted to develop in the direction of scale and intensification. Sewage and livestock and poultry breeding sewage are high-concentration organic sewage containing a large number of pathogens, and are one of the main pollution sources of water bodies. These sewage contains a large amount of organic matter, such as cellulose, starch, sugar, fat, hair, protein, etc.; also contains pathogenic bacteria, viruses and parasite eggs; inorganic salts of chloride, sulfate, phosphate, bicarbonate and Sodium, Potassium, Calcium, Magnesium, etc. Under the action of anaerobic bacteria, these sewa...

AI Technical Summary

Problems solved by technology

Under the action of anaerobic bacteria, these sewage are prone to produce odorous substances, seriously polluting the surrounding environment and groundwater of the farm, threatening the health of residents near the farm and seriously affecting the ecological environment

[0003] These sewages are mainly produced in a short period of time, and the sewage discharge volume is large, the water quality and quantity discharge are quite uneven, and the workload of sewage treatment is heavy.

The traditional process of treating these sewage has a low operating load, and it is difficult for the effluent CODcr to meet the discharge requirements of the new standard. Even if it meets the standard and is discharged, it is still unstable. The capacity of total nitrogen and total phosphorus is also low, and there are peculiar smells during the treatment process: there are also problems such as high investment cost, high energy consumption, high operating cost, complicated process, and difficult operation management.
