Description

A V-shaped filter tank to prevent algae growth mobile sunshade device

technical field

The invention relates to the technical field of sewage treatment, in particular to a mobile sunshade device for preventing algae growth in a V-shaped filter tank.

Background technique

Sewage treatment: The process of purifying sewage in order to make it meet the water quality requirements for discharge into a body of water or for reuse. Typical wastewater quality generally includes organic matter, nitrogen, phosphorus, and suspended solids. In terms of removing suspended solids and phosphorus, the V-type filter has a good treatment effect.

V-type filter is a form of fast filter. It is named because its water inlet tank is V-shaped. . After the water to be filtered passes through the water inlet valve and the square hole from the main water inlet channel, it overflows through the weir mouth and then enters the V-shaped groove submerged by the water to be filtered through the side hole. In the pool, the filtered water filtered by the homogeneous filter layer flows into the bottom space through the long-handled filter head, enters the gas-water distribution pipe channel through the square hole, and then flows into the clear water pool through the water seal well, water outlet weir and clear water channel in the pipe gallery.

The above-mentioned prior art scheme has the following defects: the sewage is rich in organic matter, nitrogen and phosphorus, which is easy to cause the algae to multiply and adhere to the filter tank. In order to inhibit the growth of algae, the method of adding chlorine is usually used, that is, adding hydrochloric acid, sodium hypochlorite and other drugs to the water body, but the addition of too much drugs will affect the water quality and adversely affect the subsequent sewage treatment.

SUMMARY OF THE INVENTION

In view of the deficiencies in the prior art, one of the purposes of the present invention is to provide a V-shaped filter tank to prevent algae growth mobile sunshade device, and a sunshade net is set directly above the filter tank to block sunlight, so that the filter tank is in a dark state , to inhibit algal blooms.

The above-mentioned purpose of the present invention is achieved through the following technical solutions:

A V-shaped filter tank prevents algae growth mobile sunshade device, which is arranged above the filter tank, including:
