Experiment on tail water treatment technology of cold water fish culture
In order to protect the ecological environment of water area,implement environmental pro-tection aquaculture,and strengthen the environmental protection construction of aquaculture indus-try,ecological treatment technologies such as solid-liquid separation,precipitation absorption,oxi-dative degradation,microbial degradation,filtration,purification,and plant absorption were adopted to carry out research on integrated treatment of tail water in cold running water aquaculture.Under the condition that the treatment system was 40％of the aquaculture area,COD,nitrogen and phos-phorus in tail water can be effectively reduced,and the treatment effect reached 100％,87.13％and 75.56％,respectively.
