Talking about Dewatering Treatment of Sludge in Pig Farm

     Pig farms have high breeding technology, unified management, reduced costs, and improved economic benefits. However, environmental problems caused by the discharge of a large number of concentrated manure and sewage have become more and more serious, which has a great impact on environmental quality. Therefore, the harmless, reduced, and resourceful treatment of manure from farms is very urgent.

Pig farm sewage mainly includes pig urine, part of pig manure and pig house washing water, which is a high-concentration organic sewage, and has a large content of suspended solids and ammonia nitrogen. After this untreated sewage enters the natural water body, it increases the content of suspended solids, organic matter and microorganisms in the water, changes the physical, chemical and biological community composition of the water body, and deteriorates the water quality. Sewage also contains a large number of pathogenic microorganisms that will spread through water bodies or through aquatic animals and plants, endangering human and livestock health.

Pig farm wastewater treatment methods can be simply summarized as physical treatment, physicochemical treatment, chemical treatment, and biological treatment. The most widely used method is biological treatment, which mainly converts the organic matter in the sewage into the biological process of microorganisms. New microbial cells and simple forms of inorganic matter can achieve the purpose of removing organic matter. The characteristics of farming wastewater are concentrated discharge, strong hydraulic shock load, high concentration of organic matter, fast hydrolysis and acidification, and good sedimentation performance. Moreover, the pig farm adopts dry cleaning method to collect pig manure. The sewage is mainly washed with flushing water. Contains a large amount of fecal water and other sundries, the sewage needs to be treated and precipitated first, and the precipitated water can be discharged, and the residue left by the precipitation also contains water, which does not meet the environmental protection standards and needs to be pressed for dehydration.

The press (heavy-duty roller slag press) mechanically presses and dehydrates pig manure residues, which greatly reduces the processing cost and becomes an indispensable production and processing equipment for drying in the feed industry. Plant tanks, slag, and pulp dehydration are different. The machinery develops and manufactures large-scale industrial-specific large-scale belt slag presses/presses, and special equipment for plant machinery dewatering, providing users with professional integrated slurry dewatering system solutions, and providing you with better services.
