Description

A kind of novel circulation-type sewage treatment pot

Technical field

The present invention relates to technical field of sewage, specially a kind of novel circulation-type sewage treatment pot.

Background technology

In recent years, with the fast development of society, the enterprise of processing and manufacturing is more and more, and the amount of industrial wastewater of discharge is more next Bigger, each enterprise increasingly payes attention to how to handle industrial wastewater, and the total amount of sewage discharge is on the increase, and intractability is continuous It increases, very burden is brought to sewage disposal, nowadays, industrial production materials, the intermediate product that industrial wastewater outflows with water With the pollutant generated in product and production process, with the rapid development of industry, the type and quantity of waste water rapidly increase, It is also increasingly extensively and serious to the pollution of water body, threaten the health and safety of the mankind；Currently, most enterprises have sewage disposal Factory, but be only limitted to production wastewater treatment rear direct emission up to standard, sewage treating efficiency is relatively low, and the rate of recovery is not high, to water resource It wastes serious sewage to be mainly made of sanitary sewage and agricultural effluent, sanitary sewage comparison of ingredients is fixed, and carbon aquation is mainly contained The organic matters such as object, protein, amino acid, fat are closed, the growth of bacterium is relatively more suitable for, become bacterium, viral life is bred Place, but sanitary sewage generally be free of it is toxic, and have certain fertilizer efficiency, can be used to irrigated farmland, the ingredient of agricultural effluent Then varied, different season, different places, the villages and small towns of different developing goals, waste water are needed with different processing sides Method, to reduce quantity of wastewater effluent and its complexity, should be built in treated sewage in conjunction with the methane-generating pit that country is wideling popularize If flushing supply (Heisui River) and other domestic waters (buck) in domestic water are separated.At buck self-purification system Reason, Heisui River and human and animal excreta are handled through anaerobic biogas generating pit, can not only reduce the discharge capacity, complexity and handling of sewage With, and to developing rural area cleaning new energy, protection living environment, the sustainable development for promoting rural economy society etc. have weight The meaning wanted, the effect of Sewage Disposal are handled production, sanitary sewage, and defined discharge standard is reached, and are protections The Sewage Disposal of the critical facility of environment, industrially developed country is very universal, and the Sewage Disposal in China villages and small towns is seldom, But it from now on can be gradually more and more.These Sewage Disposals are made really to play a role, it is also necessary to by stringent discharge system, tissue Ensure in the prior art with management system, such as application No. is 201720232509.8 patent of invention includes sewage disposal Tank, the sewage treatment pot are interior equipped with sewage rotating cylinder, the shaft
