Secondary water supply tank and method

Abstract

The invention discloses a secondary water supply tank and a method thereof. The secondary water supply tank comprises a water tank body, and is characterized in that two retaining walls perpendicularto each other are vertically arranged in the water tank body; the water tank body is divided into three areas of which the upper spaces are communicated; a water inlet tank, a sedimentation tank and aclean water tank are arranged along the water flow direction; the water inlet tank is adjacent to the sedimentation tank; the water inlet tank and the sedimentation tank are isolated by a first retaining wall; a water inlet channel for communicating the water inlet tank with the sedimentation tank is arranged at the bottom of the first retaining wall; the two tanks are separated from the clean water tank by a second retaining wall; the top of the second retaining wall is provided with an overflow channel for communicating the sedimentation tank and the clean water tank; a plurality of sedimentation units are arranged in the sedimentation tank; a municipal water pipeline is connected with the water inlet tank; a water inlet valve is arranged at a port of the pipeline; a liquid level detection mechanism used for switching the opening and closing states of the water inlet valve is arranged in the clean water tank; a blow-off pipeline is arranged at the bottom end of the sedimentation tank; and the rear side of the clean water tank is connected with a secondary water supply pipeline. The secondary water supply tank has high sedimentation efficiency, is convenient to clean and will notaffect normal secondary water supply of residents.

Description

technical field [0001] The invention relates to the field of secondary water supply in urban and rural areas, in particular to a secondary water supply tank and method. Background technique [0002] The safety of drinking water is closely related to the life and health of the people and the sustainable development of the economy and society. It is an important symbol of the development level of modern cities and the quality of life of urban and rural residents. The tap water treated by the water plant is transported to each household for secondary water supply through a huge municipal pipeline system. Nowadays, more and more communities have installed water tanks underground to store tap water, and then transport it to the households through booster pumps. Under normal circumstances, the tap water treated by the water plant can generally meet the national drinking water hygiene standards, but the huge underground pipe network system is like a large "reactor", and many water ...

Problems solved by technology

On the other hand, water supply equipment such as water tanks and pumps are often prone to pollution problems due to poor management or untimely maintenance during secondary water supply, which affects the safety of domestic water.

[0003] Moreover, the pollution problem of the secondary water supply system is universal, frequent and uncertain.

Due to the continuous expansion of the central urban area, the reconstruction of old pipes requires a large amount of work and is difficult to construct. The water supply system is greatly disturbed by operations such as water stoppage and pipe connection. The problem of "secondary pollution" has not been fundamentally solved, and there is still a gap between the quality of urban tap water entering households and people's living needs

[0004] In addition, when the secondary water supply tank is regularly maintained or cleaned, there are still some problems: on the one hand, due to the large volume of the water tank, the sediment accumulated for a long time is distributed on the inner wall of the water tank, making the cleaning task of the staff heavy; On the one hand, it is usually necessary to suspend the secondary water supply to the residents when cleaning the water tank, and then resume the water supply after the cleaning or maintenance is completed, which greatly causes the residents to use water inconveniently. In addition, the disturbance of the secondary water supply system caused by the interruption of water maintenance increases, resulting in periodic Or the possibility of sudden water supply pollution, which will also affect the secondary water supply quality of regional users
