Slaughter wastewater treatment complete device and slaughter wastewater treatment method

Abstract

The invention discloses a slaughter wastewater treatment complete device and a method for treating wastewater through the device. The device comprises a water collecting basin, a first filtering basin, an oil separating basin, a second filter, a regulating basin, an air flotation device, an integrated biological treatment device and a dosing device. The technical principles of solid-liquid separation, hydrolytic acidification and aerobiotic treatment are adopted, and compared with slaughter wastewater treatment technologies such as a conventional biological method and a physical and chemical method, the device and the method have the advantages that the device can be combined and skid-mounted in a complete set mode, the equipment occupying area is small, the treatment efficiency is high, the one-time project investment is little, and the practicability is higher.

Description

Technical field

[0001] The present invention relates to a wastewater treatment device, in particular to a complete set of slaughter wastewater treatment device and a method for treating wastewater using the device. Background technique

[0002] The waste in the slaughter process is mainly composed of high-concentration nitrogen-containing organic compounds, suspended solids, dissolved solids, protein, and oil. The waste water produced contains a lot of blood, oil, minced meat, pig hair, and undigested animals. If feed, feces, silt and other pollutants and slaughter wastewater are directly discharged without treatment, they will cause great harm to environmental sanitation and human and animal health, and cause a great waste of water resources. Although pig hair, meat scraps and undigested animal feed are all biodegradable organic pollutants, after entering the wastewater biological treatment system, it takes a relatively long residence time to be completely biodegradable, which n...
