Domestic sewage contains organic matters such as starch, protein, cellulose and mineral oil, and the chemical oxygen demand and the biological oxygen demand are high. Even if the domestic sewage after the first-stage physical treatment and the second-stage biochemical treatment is discharged into the water body, the water body is easy to eutrophicate, and red tide and other phenomena occur. After the domestic sewage is not treated, once the domestic sewage enters an underground aquifer along with water circulation, the domestic sewage can cause human poisoning after being drunk by human beings, so the domestic sewage needs to be treated in time.

At present, most of rural domestic sewage is directly discharged without being treated, so that the serious pollution of water environment is caused, and at present, an aerobic biological treatment system is generally adopted for domestic treatment of the sewage. Although the aerobic biological treatment system has the characteristics of high treatment load and strong treatment capacity, the disadvantages of high treatment cost and high one-time investment are caused when the aerobic biological treatment system is used due to poor biodegradability of rural domestic sewage, so that the aerobic biological treatment system cannot be popularized in the aspect of treating rural domestic sewage.
