High-quality drinking water supply system

Abstract

The invention relates to a high-quality drinking water supply system. The high-quality drinking water supply system comprises a filtering module, a water tank and a pump room which are connected in sequence, wherein the input end of the filtering module is connected with a water supply pipe at the tail end of a municipal water supply pipe network, and the output end of the pump room is connected with a vertical pipe; the vertical pipe is further connected with one end of a water return pipe, and the other end of the water return pipe is connected with the filtering module through a backwash valve; and the vertical pipe is higher than the filtering module, so that water in the vertical pipe can return to the filtering module through the water return pipe under the action of gravity after the pump room stops running. The high-quality drinking water supply system can ensure the high-quality index of drinking water in the user pipe network.

Description

technical field [0001] The invention relates to the technical field of drinking water supply, in particular to a high-quality drinking water supply system. Background technique [0002] At present, drinking water for residents is basically supplied by municipal tap water pipe network and secondary pressurized water supply. With the improvement of people's living standards, compared with the national standard water quality indicators for drinking water, residents put forward higher requirements for drinking water, especially for the improvement of microbial indicators and heavy metal indicators in drinking water, for total chlorine, free chlorine, Ozone, smell and taste, taste also put forward higher requirements. At present, the pipes in the water supply network mainly use different materials such as ductile iron pipes, galvanized pipes, steel pipes, and PE pipes, and a large number of water tanks are installed on the water supply pipe network. Secondary pollution and dete...

Problems solved by technology

At present, the pipes in the water supply network mainly use different materials such as ductile iron pipes, galvanized pipes, steel pipes, and PE pipes, and a large number of water tanks are installed on the water supply pipe network. Secondary pollution and deterioration of water quality lead to a decline in the quality of drinking water leading to users, or even substandard situations

In addition, in the current design of the drinking water supply system of the building, the standpipe is not designed with a return pipe. If some floors or some users do not use water for a long time, the water in the standpipe and the user pipe network will remain in the pipeline for a long time and cause water quality problems. go bad
