Large chemical wastewater filtering device with replaceable filter screen

Abstract

The invention discloses a large chemical wastewater filtering device with a replaceable filter screen. The large chemical wastewater filtering device comprises a mainstream channel for discharging chemical wastewater, a partition plate, an opening and closing mechanism, a filtering mechanism, and a controller for controlling the opening and closing mechanism and the filtering mechanism to work. The opening and closing mechanism and the filtering mechanism are installed on the mainstream channel and are sequentially distributed in the flowing direction of the wastewater. When the wastewater ispurified by the purifying device, filtering is conducted through two channels; the two channels are in different opening and closing states; when a filtering plate in one channel is taken out to be cleaned, wastewater discharging and filtering of the other channel cannot be affected, and the continuous wastewater purifying is ensured.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a large-scale chemical sewage filter device with a replaceable filter screen. Background technique [0002] Industrial wastewater refers to the wastewater, sewage and waste liquid produced in the process of industrial production, which contains heavy metal impurities produced in the process of industrial production. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread. And seriously, when traditional sewage purification equipment purifies sewage, when there are many impurities on the filter, the purification effect is poor, so the filter needs to be replaced. During the replacement of the filter, the sewage will stop purifying, reducing the pollution of sewage. s efficiency. Contents of the invention [0003] In order to achieve the above object, the present in...
