Device for physically purifying wastewater

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a device for physically purifying wastewater, which comprises a feeding mechanism, a purifying tank, a scraping mechanism and a filtering mechanism, the feeding mechanism is positioned above the purifying tank, and the scraping mechanism and the filtering mechanism are positioned inside the purifying tank; the device comprises a purification tank, the inner walls of the two sides of the purification tank are rotationally connected with the same threaded rod, the circumferential outer wall of the threaded rod is rotationally connected with a first sliding block through threads, a liquid storage shell is installed on the outer wall of the top of the first sliding block, and a liquid pump is installed on the inner wall of the bottom of the liquid storage shell. According to the sewage treatment device, a flocculating agent is sprayed out through a liquid spraying head on a liquid outlet pipe, so that suspended particles in sewage lose stability, a large number of suspended matters in the wastewater are removed, the water treatment effect is achieved, the flocculating agent and the sewage are fully mixed through a mixing plate, and the purification effect is improved.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a device for physically purifying waste water. Background technique [0002] Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, so as to achieve wastewater recovery and reuse, make full use of water resources, separate and recover insoluble suspended state pollution in wastewater through physical action The method of separation can be divided into gravity separation method, centrifugal separation method and sieve retention method, etc. The processing units belonging to gravity separation method include sedimentation, floating (air flotation), etc. The corresponding processing equipment is grit chamber and sedimentation tank. , grease trap, air flotation pool and its accessories, etc. [0003] When purifying wastewater, it is first necessary to add a flocculant to the wastewater. Now it ...

Problems solved by technology

[0003] When purifying wastewater, it is first necessary to add a flocculant to the wastewater. Now it is artificially sprinkled in the sewage, and the flocculant is mixed with the sewage by adding the impact force of the wastewater, but there is still insufficient mixing, which affects the removal of suspension. The effect of state pollutants, there are limitations in use, so there is an urgent need for a device for physically purifying wastewater to solve the above problems
