Generally, livestock wastewater is also called livestock wastewater, and refers to a mixture of livestock manure and livestock wastewater discharge facility cleared of livestock manure.

As the consumption of livestock products continues to increase due to the recent economic growth and the improvement of the income level of the people, the annual domestic livestock manure output has steadily increased to about 46.77 million tonnes in 2008 and 49.95 million tonnes in 2010 Respectively.

Although the amount of livestock manure produced is relatively small compared to industrial wastewater and domestic wastewater and is smaller than human manure, it contains a large amount of pollutants, so that the concentration of organic matter is high and the pollution load on the water system And about 8% of the total.

The actual human BOD (biochemical oxygen demand) concentration of manure is 12,500ppm, compared to 28,500ppm for cows and beef cattle, 68,000ppm for pigs and 65,000ppm for chickens.

Particularly, pigs are the most difficult to treat livestock manure. The pigs have a daily weight of 5.4 kg and a daily BOD of 130 g per day, which is the average weight of 60 kg adult manure. 1.5 kg / day, and the discharged BOD is 13 g / day.

However, livestock manure has a large fluctuation of wastewater properties due to sources, collection methods, and feeds, and contains high concentrations of organic matter and nutrients. Therefore, , The water quality of the river deteriorates and the lake eutrophication is caused. In addition, the pollution causes harmful factors such as bad odor and pest damage, which causes serious environmental pollution.

Accordingly, various methods for purifying the supernatant water (commonly referred to as "supernatural water") have been proposed and applied to conventional livestock wastewater treatment facilities after solid-liquid separation of livestock manure, There is a lot of difficulty in the treatment of animal wastewater because there are many floats, high concentrations of organic pollutants, high nitrogen concentration, excessive SS components, and wastewater.
