Environment-friendly sewage treatment device

Abstract

The invention provides an environment-friendly sewage treatment device and relates to the field of sewage treatment. The environment-friendly sewage treatment device comprises a treatment tank and a slide rod, wherein springs are fixedly connected with the two sides of an inner wall of the treatment tank; one end, far away from the inner wall of the treatment tank, of each spring is fixedly connected with a filter cartridge; an upper slide rail and a lower slide rail are fixedly connected with the two sides of the inner wall of the filter cartridge; the two sides of the back surface of the slide rod are movably connected with first pulleys through rotating shafts; and the tops of the first pulleys are connected with the bottoms of the upper slide rails in a sliding manner. When the deviceis in use, and the filter cartridge reciprocates to the right and left, an anti-blocking block can slide to the right and left oppositely in an inner cavity of the filter cartridge, so that the anti-blocking block can clear impurities at the top of a steel wire filter screen conveniently; a situation of blocking of the steel wire filter screen due to the impurities in sewage is avoided; the devicehas the characteristic that a filter device can be prevented from blocking; and the device is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage treatment device. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollution. things etc. [0003] In order to make sewage reusable, many sewage treatment devices have appeared on the market. However, in the process of field use, the filter devices of these sewage treatment devices are often prone to clogging when they are used, which also leads to the need for frequent sewage treatment devices. Overhaul, so that the efficiency of sewage treatment is greatly reduced. [0004] Therefore, the present invention provides an environmentally friendly sewage treatment device, which...

Problems solved by technology

[0003] In order to make sewage reusable, many sewage treatment devices have appeared on the market. However, in the process of field use, the filter devices of these sewage treatment devices are often prone to clogging when they are used, which also leads to the need for frequent sewage treatment devices. overhaul, greatly reducing the efficiency of sewage treatment

[0004] Therefore, the present invention provides an environmentally friendly sewage treatment device, which has the characteristics of preventing the filter device from being blocked, and solves the problem that the filter device is often prone to blockage when the traditional five-book processing device is in use.
