The aquaculture wastewater is a special wastewater, and compared with other sewages, the aquaculture wastewater has a higher COD value, is rich in N, P and other nutrient substances, and has the defects of high treatment difficulty because solid residues in water are mainly organic substances.
At present, the treatment process of general sewage is more, and the treatment process is mainly divided into a physical method, a biological method and a chemical method. Wherein, the physical method mainly utilizes physical action to separate non-soluble substances in the sewage, and does not change chemical properties in the treatment process; the biological method utilizes the metabolism function of microorganisms to decompose and oxidize organic matters in a dissolved or colloidal state in the sewage into stable inorganic substances, so that the sewage is purified; the chemical method is a method for treating or recovering dissolved substances or colloidal substances of sewage by using a chemical reaction, and is often used for industrial wastewater. However, most sewage treatment processes are complex to operate, and involve a lot of equipment and reagents, so that the treatment cost is high, the treatment effect is unstable, and the hidden danger of secondary pollution exists. In addition, these conventional sewage treatment methods are not suitable for treating special sewage such as aquaculture wastewater.
