Self-returning sedimentation zone structure in integrated sewage treatment equipment

Abstract

The invention relates to a self-returning sedimentation zone structure in integrated sewage treatment equipment, which includes a tank body, manholes are arranged on the top of the tank body, and sludge air lift inlets are respectively arranged on the upper part of the tank body wall. mouth and sludge outlet, a standpipe settler is provided above the inside of the tank, a sewage inlet is provided on the standpipe settler, a water blocking cap is provided at the bottom of the standpipe settler, and A support is provided under the inside of the tank, and a sludge combination pipe is provided on the support, and an air inlet and a mud outlet are respectively provided on the sludge combination pipe, and the air inlet passes through the first pipeline and the The sludge gas-lifting inlet is connected to each other, and the sludge outlet is connected to the sludge outlet through a second pipeline. The invention has compact structure, automatic discharge of sludge, low energy consumption and long service life.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sedimentation zone structure. Background technique [0002] With the rapid growth of my country's economy, the acceleration of urbanization, the continuous improvement of rural living standards, and the development of rural livestock and poultry breeding, aquaculture, and agricultural and sideline product processing, the amount of domestic sewage and wastewater produced in villages and towns is increasing day by day. Most of these sewage are directly discharged into rivers and lakes without any treatment, which makes the water pollution more and more serious. In this context, my country's "Eleventh Five-Year Plan" put forward the major historical task of building a new socialist countryside, and clarified the construction goals of "development of production, affluent life, civilized rural customs, clean and tidy village appearance, and democratic management". Streng...

AI Technical Summary

Problems solved by technology

However, many problems were found after the specific implementation, such as the stability of biological treatment technology and the degree of maintenance and supervision of integrated equipment cannot guarantee its long-term durability, etc.

The most important thing is that the sludge in the sedimentation area cannot be discharged automatically and needs to be cleaned manually, which wastes a lot of manpower and material resources
