Tap water storage tank capable of self-purifying depending on cladophora

Abstract

The invention discloses a tap water storage tank capable of self-purifying depending on cladophora. The tap water storage tank comprises a tank body and a tank cover, the tank body and the tank cover are light-admitting bodies, a chamber of the tank body is divided into an upper chamber and a lower chamber by a light-admitting partition board which is installed in the tank body, a plurality of water penetrating holes communicated with the upper chamber and the lower chamber are formed in the light-admitting partition board, a high-calcium-magnesite stone granular layer is laid on the upper surface of the light-admitting partition board, the inner bottom face of the bottom of the tank body is an inclined face which inclines downwards, a sewage discharge outlet penetrating through the bottom of the tank body is formed in the lowest portion of the inner bottom face of the tank body, and the water inlet which is located above the light-admitting partition board and the water outlet which is located above the light-admitting partition board are formed in the sidewall of the tank body. Compared with the prior art, a survival environment is provided for the cladophora, self-purifying of water in the tank body can be conducted by the cladophora, cleaning of the tank body is not needed, the removal of residual chlorine, organic chloride, organic matter and ammonia nitrogen in a water body is achieved, and microalgae breeding in the water is inhibited.

Description

technical field [0001] The invention relates to a water storage tank, in particular to a tap water storage tank for purifying tap water relying on Cladophorus algae. Background technique [0002] The roof of a traditional residential area is equipped with a tap water storage tank for water storage, which usually stores tap water all year round and is the last storage device before tap water enters the home. Because the water supply of the tap water storage tank generally reaches the tolerance limit of 24 hours of water cut-off, even for several days, the volume of the tap water storage tank is generally large, and this large-volume tap water storage tank can provide Cleaning is inconvenient. According to statistics, the tap water storage tanks in most residential areas lack effective cleaning, which seriously affects the water supply quality. In addition, the current pollution problems of tap water quality, tap water pipelines, secondary pressurized storage tanks, etc. are ...

Problems solved by technology

Because the water supply of the tap water storage tank generally reaches the tolerance limit of 24 hours of water cut-off, even for several days, the volume of the tap water storage tank is generally large, and this large-volume tap water storage tank can provide Cleaning causes inconvenience. According to statistics, the tap water storage tanks in most residential areas are not cleaned effectively, which seriously affects the water supply quality.

In addition, the current pollution problems of tap water quality, tap water pipelines, secondary pressurized storage tanks, etc. are still difficult to solve, and the purification system for the "last mile of water supply" is still lacking. Only conventional disinfectants and regular cleaning are used. It can reduce sediment pollution, but fails to improve the quality of tap water; therefore, the existing tap water storage tank also needs to meet: ① be able to remove a certain concentration of residual chlorine and organic chlorine, as well as residual organic matter, ammonia nitrogen, etc. in the water; ② be able to remove The rust, mud, etc. deposited at Jiashi, ③ the above three purification functions that can inhibit the growth of microalgae can ensure the drinking safety of residents

However, the existing tap water storage tanks are generally aseptic sealed boxes with a light-shielding upper cover, which is relatively simple and simple, and cannot meet the three purification functions required by the tap water storage tanks, thus making drinking water unsafe for residents
