Pig Farm Wastewater Treatment

Pig farm wastewater is mainly composed ofurine, feces, and trough water. The pollutant concentrations in the wastewater produced by different manure cleaning methods are different. At present, the main manure cleaning methods in pig farms are soaking manure and mechanical manure scraping. Mechanical manure scraping is divided into flat manure scraping and V-shaped manure scraping. Among them, the soaking time of feces and urine in the liquid foam manure cleaning method is longer. During the soaking process, more organic matter is dissolved in the water, which increases various pollution indicators. Flat manure scraping is a mechanical manure cleaning method that does not separate urine and feces. The soaking time of pig manure is shorter, and its various pollution indicators are lower than soaking manure. V-shaped manure scraping is a mechanical manure cleaning method that separates urine and feces. Pig manure is basically not soaked, and various pollution indicators are lower.
