Abstract

The present invention provides a method for treating aquaculture wastewater. The method includes stages, pretreatment, biological treatment and advanced treatment. The pretreatment stage comprises grating slag removal, primary sedimentation adjustment and flocculation sedimentation. The biological treatment stage includes anaerobic treatment, multi-stage biological contact oxidation process. The advanced treatment stage includes decolorization treatment and membrane bioreactor treatment. The method for treating aquaculture wastewater has the advantages of low comprehensive energy consumption, strong impact resistance system, small land occupation and good treatment effect.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a method for treating aquaculture wastewater. Background technique [0002] Aquaculture is an important industry for the development of rural areas in my country. In recent years, with the continuous expansion of the breeding scale and the sharp increase in the number of breeding, a large number of livestock and poultry feces and sewage have become pollution sources. If the pollution generated by these farms is not dealt with in time, it will definitely cause great harm to the environment. The deterioration of the ecological environment, the decline in the quality of livestock and poultry products and the danger to human health, and the lagging of pollution control technology in the breeding industry will seriously restrict the sustainable development of the breeding industry. [0003] At present, there are two main types of treatment methods for large-scale livestock and pou...
