Sewage purification device

Abstract

The invention relates to the technical field of sewage treatment, in particular to a sewage purification device. The device comprises a casing, wherein a plurality of supporting legs are connected tothe lower end of the casing; a drain pipe is connected to the lower part of one side of the outer wall of the casing, and a drain valve is arranged on the drain pipe; a water inlet pipe is arranged atthe upper part of one side of the outer wall of the casing, and a water inlet valve is arranged on the water inlet pipe; a plurality of inserting plates are arranged at the lower part of the inner wall of the casing; filter devices are arranged inside insertion slots; a sealing device is arranged inside an arc-shaped groove and comprises an arc-shaped plate, insertion heads matched with insertionholes are symmetrically arranged in the arc-shaped hole, a rotating rod is inserted in one side of the arc-shaped plate, the other end of the rotating rod extends into the arc-shaped hole, and the outer side of the rotating rod is sleeved with a gear meshed with teeth. The device is convenient and quick to mount and fix, saves time and labor, can improve working efficiency and save cost, and canbe disassembled and assembled by non-professional workers.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage purification device. Background technique [0002] In most parts of the world, the water quality is seriously polluted. Lakes, rivers, and groundwater have all suffered from varying degrees of pollution, and most of them have excessive heavy metals and agricultural pesticide residues. Nowadays, the methods of water treatment mainly include physical and chemical methods. Physical methods include the use of various filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude impurities in water. The most important adsorption method is adsorption with activated carbon. The barrier method is to pass water through the filter material, so that the larger impurities cannot pass through, and then obtain cleaner water. In addition, the physical method also includes the precipitation method, which is to let the impurities with a sma...

Problems solved by technology

[0003] The existing physical methods for water treatment usually do not treat the inner wall of the purification device. After a period of use, it usually emits an unpleasant smell due to a large amount of residue attached to the inner wall, which is not conducive to use. At the same time, the existing purification device uses It is difficult to disassemble and assemble the filter layer, and it is time-consuming and laborious to disassemble, replace or repair the filter layer, and it also requires professionals to carry out maintenance and treatment, which increases the cost and greatly reduces the work efficiency. Therefore, we propose a sewage purification device
