Problems solved by technology

[0003] However, the application of the above technologies in the field of small-flow, high-concentration sewage treatment is limited. Due to the small amount of water, the reaction section of the high-efficiency sedimentation tank is prone to alum flower precipitation, and black mud floating phenomenon will occur for a long time
However, the current anaerobic reactors are generally high in height, and it is difficult to adopt them in small-scale sewage treatment systems.

Abstract

The invention discloses high-density sedimentation internal circulating integrated sewage treatment equipment and relates to the field of sewage treatment technology. The sewage treatment equipment comprises a high-density floc settling device, an anaerobic reaction device, an aerobic reaction device and a settling device. according to the sewage treatment equipment, a deflector is arranged in the high-density floc settling device, so as to change the flow state of fluid and avoid generation of floc settling; a jet water distributor is added in the anaerobic reaction device to avoid short flow of sediment water from the high-density floc settling device; under strong impact of jet flow, sludge at the bottom of the anaerobic reaction device is completely mixed with sewage, and no dead angle is generated during a stirring process, so that uniformity of water distribution and complete reaction are guaranteed; the sewage treatment equipment has a remarkable effect in small-scale sewage treatment, and can be applied to treatment of domestic sewage and industrial sewage as well as to nitrogen and phosphorus removal processes; since four devices are designed to be a whole, the structure of the equipment is compact and investment cost and operation cost are reduced.

Description

technical field [0001] The application relates to the technical field of sewage treatment, in particular to high-density sedimentation internal circulation integrated sewage treatment equipment. Background technique [0002] In recent years, with the development of my country's environmental protection industry, sewage treatment technology has also made great progress. Among them, high-efficiency sedimentation tanks and anaerobic reactors have been widely used. High-efficiency sedimentation is a technology that combines ordinary coagulation sedimentation with shallow sedimentation to form high-density floc sedimentation, thereby improving sedimentation efficiency and reducing floor space. Anaerobic reactors are widely used due to their advantages of high load and low energy consumption. [0003] However, the application of the above technologies in the field of small-flow, high-concentration sewage treatment is limited. Due to the small amount of water, the reaction secti...
