Manure deodorization harmless disposal system and method

Abstract

The invention provides a manure deodorization harmless disposal system and method. Clean water is directly pumped out through a membrane disposal pond via a membrane separation unit, and manure liquid suspended particles can be directly removed; the PH value of manure liquid is automatically tested through the integrated circuit and pipeline technology, the flow of alum and aluminum chloride is obtained, human errors and cost are reduced, finally, manure odors of cooperative enterprises are directly reduced, harm of stinks to growth of livestock and poultry and the surrounding is reduced, volatilization of ammonia gas in pig manure is reduced, losses of nitrogen in the manure are avoided, the fertilizer value of fertilizer is improved, the content of soluble phosphorus of the manure is reduced, contamination of phosphorus of the manure to soil is avoided, water-soluble copper, zinc, lead and cadmium are reduced through adsorption, fixation, flocculation and other effects, stereoscopic purification disposal is achieved, and the labor cost for pig manure disposal is reduced.

Description

technical field [0001] The invention relates to the field of deodorizing and harmless treatment of feces, in particular to a deodorizing and harmless treatment system and a treatment method for feces. Background technique [0002] With the rapid development of standardized and intensive pig farming in my country, pig production has become a huge industry. According to data released by the National Bureau of Statistics in 2014, there were 465.83 million live pigs, a year-on-year decrease of 1.7%; 735.1 million live pigs were slaughtered, a year-on-year increase of 2.7%; pork output was 56.71 million tons, an increase of 3.2%. The annual slaughter of commercial pigs exceeds 600 million. At the same time, the discharge of manure and sewage from pig farms is also increasing. According to statistics, there are about 65,000 to 70,000 large-scale pig farms nationwide, and the total amount of pig manure produced every year is about 200 million tons, and the total amount of pig uri...

AI Technical Summary

Problems solved by technology

Because the PH value was not effectively lowered before the solid-liquid separation, the ammonia fertilizer in the feces would flow into the air in the form of ammonia gas, which would also greatly pollute the environment.

At the same time, it does not effectively reduce the pollution of nitrogen, phosphorus and heavy metals in solid and liquid manure
