Efficient urban sewage treatment system

Abstract

The invention discloses an efficient urban sewage treatment system which comprises a stirring box, a filtering box and a purifying box.The stirring box is located at the upper end of the filtering box.The stirring box and the filtering box are connected through a water conveying pipe.A box cover is arranged at the upper end of the stirring box.The upper end of the box cover is provided with a driving device and a sewage inlet pipeline.The driving device is in drive connection with a stirring shaft.The stirring shaft penetrates through the box cover and extends into the stirring box.Stirring blades are arranged at the portion, inside the stirring box, of the stirring shaft at equal intervals.A filtering layer is arranged at the bottom inside the stirring box.An ultrasonic oscillator is arranged on the inner side wall of the filtering box.A groove is formed in the bottom inside the filtering box.A stretchable device is arranged inside the groove.An ultrasonic probe is arranged at the upper end of the stretchable device.A water suction pump is arranged at the bottom inside the filtering box.According to the efficient urban sewage treatment system, the sewage treatment difficulty is greatly lowered, the sewage treatment effect is improved, it is ensured that purified water reaches the quality standard, and the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment systems, in particular to an efficient urban domestic sewage treatment system. Background technique [0002] Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, so as to achieve wastewater recycling and reuse, and make full use of water resources. The existing physical methods are to separate and recycle wastewater through physical action. Wastewater treatment methods for insoluble suspended pollutants can be divided into gravity separation method, centrifugal separation method and sieve retention method, etc. The existing chemical method is to separate and remove waste water through chemical reaction and mass transfer. Pollutants in a dissolved or colloidal state or a wastewater treatment method that converts them into harmless substances. The existing biological method is to convert organic pollutants in a so...

Problems solved by technology

Activated sludge is a general term for microbial groups and their attached organic and inorganic substances. Activated sludge can be divided into aerobic activated sludge and anaerobic granular activated sludge. Activated sludge is mainly used to treat sewage, but activated sludge The sewage treated with mud contains various impurities that have not been removed, and the water purification effect is not good. Therefore, we have proposed a high-efficiency urban domestic sewage treatment system to solve the above problems
