Septic tank with duplex biochemical functions

Abstract

Along with the rapid development of social economy, the environment protection consciousness of people is improved, and higher requirements are also provided for the treatment function and the use effect of septic tanks and sewage treatment facilities. Therefore, a septic tank with good septic tank use effects and complete sewage biochemical treatment functions becomes a hot topic of industrial research and development and the development trend of living quarters and residential building and planning in future. The invention provides the septic tank with duplex biochemical functions, the existing single anaerobic direct flow flashing septic treatment mode in common use is improved into the facultative-anaerobic-aerobic backflow type septic tank, the improved septic tank has good septic and sewage treatment effects, can be singly used as the septic tank and can also be used as a domestic sewage treatment reuse device, and the treated outlet water conforms to the national nondrinking water reuse water standard.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and is particularly suitable for the domestic sewage treatment of living quarters and residential households, or as a septic tank technical facility with dual biochemical functions used as a septic tank. Background technique [0002] During the construction process of living quarters and residential households, septic tanks or sewage treatment facilities are planned to treat domestic sewage, feces and other sewage. With the rapid development of social economy and the improvement of people's awareness of environmental protection, septic tanks The treatment function and use effect of the pool and sewage treatment facilities have also put forward higher requirements. Therefore, a multi-functional septic tank with both septic tank functions and complete sewage biochemical treatment has become a hot topic in research and development in the industry. Topics and the future development direction...

Problems solved by technology

The present invention changes the original principle of direct-current flooding septic to the principle of circulating flooding septic. Because the tank body is equipped with a biological packing box, it has a certain anaerobic biodegradation function, and both the use effect and the treatment of water are better than ordinary three The grade septic tank is superior, but the circulating flooding septic tank after its transformation still has the disadvantages of accumulation and blockage due to the solid fecal sewage floating up and not completely melting, which affects the septic effect, and the overwater Channels and through-holes are set in the stuffing box, and the undissolved fecal dirt is blocked by the stuffing, and it is easier to accumulate in the stuffing box, and even block the water channel. Once it is blocked, it will be difficult to clear it. , the monolithic septic tank is only limited to anaerobic operation, does not have a complete anaerobic-aerobic biochemical reaction function, the removal capacity of organic pollutants is limited, especially ammonia nitrogen cannot be eliminated at all, and the quality of effluent water is far from reaching The miscellaneous water reuse standard stipulated by the state is only limited to use as a septic tank
