Slaughterhouse wastewater treatment
Treatment of slaughterhouse wastewater：
Coagulation method: mainly coagulant sedimentation and coagulation method, the main removal of the insoluble substance of the hydrocolloidal class, and the removal of poor dissolved substances in water
Oxidation method: common methods include ozone oxidation, pharmaceutical oxidation (fenton, sodium hypochlorite, chlorine dioxide, etc.). It is mainly aimed at toxic and harmful classes, which can limit organisms, and that can not be reduced by conventional treatment methods.
The slaughtering wastewater contains a large amount of organic matter, which has high efficiency, low operating cost and stable reliability. At present, the domestic slaughter wastewater treatment has been given priority to with biological treatment, especially in the anaerobic - aerobic biological method. As the technology, UASB, SBR, accelerating aeration and biological contact oxidation method, blast aeration, jet aeration activated sludge process and biological turnplate method, etc.
