Zero-emission organic concentrated water recycling method

The invention discloses a recycling method of zero-emission organic concentrated water, and belongs to the technical field of sewage treatment. The method comprises the following steps: carrying out biochemical treatment on zero-emission organic concentrated water in a sewage biochemical treatment device; the sewage biochemical treatment device contains 30-40vt% of activated sludge; the activated sludge contains 2500-3500 mg/L of microorganisms, and the microorganisms simultaneously contain anaerobic bacteria and aerobic bacteria in a mass ratio of 1: (1.5-2.5). The characteristic of high COD of the organic concentrated water is fully utilized, the organic concentrated water serves as one of biochemical sludge nutrient sources, organic matter is subjected to degradation reaction under the catalytic action of microorganisms, organisms, especially microorganisms, in the water body can enable many substances to be subjected to biochemical reaction, and therefore most of the organic matter is degraded into simple
