Miniature sewage layered filtering system

Abstract

The invention provides a miniature sewage layered filtering system, and belongs to the technical field of sewage purification. The problems that existing sewage treatment equipment is large in size, troublesome to maintain and maintain and poor in filtering effect are solved. The device comprises a layered filter, a filtering and precipitating bin, a filter base, an ultrasonic cleaning bin, a first purified water discharge pipe and a second purified water discharge pipe, the layered filter is arranged in the filter base and is in sealed connection with the filter base, the lower end of the filtering and precipitating bin extends into the filter base, sleeves the middle lower section of the layered filter and is in sealed connection with the layered filter, and the filtering and precipitating bin and the layered filter are coaxially communicated; a first cylindrical water filter screen, a second cylindrical water filter screen and a third cylindrical water filter screen which are coaxially arranged from inside to outside are arranged in the layered filter. The device is small in occupied space, high in efficiency and easy and convenient to operate; according to the sewage treatment device, careful layered filtration of sewage can be realized, and the sewage is filtered by ultrasonic waves and finally becomes real purified water, so that the environment-friendly and energy-saving effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of sewage purification, in particular to a micro-sewage layered filtration system. Background technique [0002] At present, as the domestic economy develops faster and faster, the sources of pollution are gradually increasing, and sewage treatment has become a difficult problem for the green environment. If the sewage is discharged without treatment, it will cause environmental damage. Direct pollution endangers people's health, and its consequences are very serious. In the existing sewage treatment technology, most of the equipment is relatively large in size, which leads to troublesome maintenance and follow-up care. Therefore, a sewage treatment system with small footprint, high efficiency and easy operation is needed now. Contents of the invention [0003] In view of this, the present invention aims to propose a micro-sewage layered filtration system to solve the problems of large volume, troublesome...
