Description

Compound for organic sewage treatment and preparation process thereof

Technical Field

The invention belongs to the technical field of sewage treatment, and particularly relates to a compound for organic sewage treatment and a preparation process thereof.

Technical Field

The organic sewage contains organic substances such as carbohydrate, protein, grease, lignin and the like in domestic sewage, food processing, breeding, paper making and the like. These substances are present in the sewage in a suspended or dissolved state and can be decomposed by biochemical action of microorganisms. Oxygen is consumed in its decomposition process and is therefore referred to as an oxygen-consuming contaminant. Such contaminants can cause a reduction in dissolved oxygen in the water, affecting the growth of fish and other aquatic organisms. After the dissolved oxygen in water is exhausted, the organic matter is anaerobically decomposed to generate hydrogen sulfide, ammonia, mercaptan and other bad smells, which deteriorates the water quality. At present, the sewage treatment technology mainly comprises the following steps: (1) adding chemical substances into the sewage to degrade or recover pollutants in the sewage, wherein the chemical substances comprise a precipitation method, a neutralization method, an oxidation-reduction method, a chemical physical disinfection method and the like; (2) removing pollutants in the sewage by a physical and chemical method, wherein the method comprises an ion exchange method, an adsorption method, a membrane separation method and the like; (3) separating and recovering insoluble pollutants in the sewage by a physical method; (4) a method for degrading organic pollutants in sewage into stable and harmless substances by the metabolism of microorganisms. Organic sewage treatment technologies are roughly classified into 3 types: physical and chemical treatment technology, chemical treatment technology and biological treatment technology. The three technologies have certain defects in treating organic sewage, such as: high operation cost, more and complex equipment, complex process flow, and the like, and needs various methods for comprehensive treatment.

The technology for treating environmental pollution by decomposing pollutants with microorganisms starts from 40-50 years of the last century, but the technology shows unique functions and remarkable superiority after the generation of the pollutants, thereby causing high attention to the environment boundaries of various countries. The american environment expert notes: the biological pollution control technology has the obvious characteristic of being a pollutant eliminating technology rather than a pollutant separating and transferring technology. The microbes decompose the toxic and harmful pollutants into non-toxic and harmless substances such as water, carbon dioxide, nitrogen, methane and the like through the metabolism activity of the microbes. Because the decomposition activity of the microorganism is carried out at normal temperature and normal pressure, the method has the characteristics of low energy consumption (methane energy can be generated by anaerobic treatment of high-concentration pollutants), low equipment investment, simple operation and management, low cost and high treatment efficiency.

Therefore, how to treat the organic sewage by using the microorganisms has practical significance in that the sewage treatment process is simpler and the investment is lower.
