Livestock Husbandry Wastewater Treatment

Characteristics of Livestock Wastewater

Livestock wastewater, which is a high concentration organic sewage, mainly includes urine, feed residues, residual feces and flushing water and has a large content of suspended solids and ammonia nitrogen. It also contains a large number of pathogenic microorganisms, which will spread out in water and thus endanger human and animal health.

“Three High” characteristics are typical seen in livestock wastewater: COD 3000-12000mg/l, ammonia nitrogen 800-2200mg/l, and suspended solids concentration 2000 mg/l. There are also a number of factors that contribute to livestock wastewater characteristics, such as large drainage, high concentration, strong hydraulic impact load, high hardness, high concentration of organic matter, fast hydrolysis and acidification, deep color, and good biodegradability so on.

WASTEWATER Livestock Wastewater

Livestock farming plays an essential role in economic development for many countries.

In agriculture industry, livestock provides a significant stimulus to agriculture development through manure, fuel, as well as fertilizers. Livestock farming presents many undisputable opportunities but then again challenges that farmers need to face. One of the challenges that we would like to focus on is the harmful impact of the discharge of the livestock wastewater into ecological system.
