The general process of sewage treatment is to remove pollutants such as heavy metal, cyanide and large particulate matters through physicochemical treatment, and then carry out biochemical treatment to eliminate chemical oxygen demand, total phosphorus, ammonia nitrogen and total nitrogen in water. The biochemical treatment of sewage usually comprises anaerobic treatment, anoxic treatment and aerobic treatment, wherein the anaerobic treatment and the anoxic treatment mainly have the functions of decomposing macromolecular organic matters in the sewage and removing total phosphorus and total nitrogen, and the aerobic treatment mainly aims at decomposing the micromolecular organic matters and removing ammonia nitrogen. The aerobic treatment process can be divided into an activated sludge process and a biofilm process, and the principle is that organic matters are decomposed into biological energy and inorganic matters through the metabolic process of aerobic microorganisms.
At present, the mode of strengthening the aerobic treatment system of industrial and domestic sewage treatment plants is that aerobic bacteria are directly added into an activated sludge tank or a biomembrane reaction tank, and has the following defects: the daily wastewater treatment capacity of a general sewage treatment plant is large, but the daily wastewater treatment capacity is influenced by shortage of land area and overhigh building cost after environmental protection standard extraction, and the scale of a biochemical pool is less and redundant, so bacteria are directly added, most of bacteria can bring too fast water flow out of the system, and loss and waste are caused; the nutrient substances in the industrial sewage are generally low in content, if the bacteria cannot quickly draw the nutrients from the water body at the initial feeding stage, the bacteria are directly fed into a biochemical system, and the quality of the nutrients required by the initial growth of the bacteria is difficult to calculate by workers, so that the self-decomposition of the bacteria is easily caused, namely the phenomenon of bacterial stripping of an aerobic pool; industrial wastewater such as electroplating wastewater, circuit board wastewater and the like contains a large amount of harmful substances such as heavy metal, cyanide or sulfide, and the residues still inhibit the growth of bacteria although the harmful substances are removed to reach the standard through physical and chemical treatment.
