Secondary water supply non-negative pressure overlying water purification equipment

Abstract

The invention relates to secondary water supply non-negative pressure overlying water purification equipment. The equipment comprises an inorganic membrane filtration module located on one side, a pump set module located in the center and a non-negative pressure compensation module located on the other side. The inorganic membrane filtration module comprises a lower cavity, a middle cavity and a hollow upper cavity which are connected with one another from bottom to top; a filtration membrane group is arranged in the middle cavity; the pump set module comprises a pump set, and a water inlet main pipe and a water outlet main pipe are arranged on the side wall of the pump set module; the non-negative pressure compensation module comprises a water storage tank, a negative pressure protection switching device and a water outlet compensation device. The negative pressure protection switching device is arranged at the end, close to the water storage tank, of the pump set water inlet pipe, and a water outlet of the water storage tank is connected with the water outlet main pipe through the water outlet compensation device. The filtering membrane module technology is applied to water treatment, the technical problem of water treatment in existing secondary water supply is solved, the water quality safety is guaranteed, and the device has the advantages of being stable in performance, long in service life and the like.

Description

technical field [0001] The invention belongs to the technical field of urban secondary water supply, in particular to a non-negative pressure stacked water purification device for secondary water supply. Background technique [0002] No negative pressure water supply equipment is a pressurized water supply unit that is directly connected to the municipal water supply pipe network. On the basis of the residual pressure of the municipal pipe network, the water supply is stacked in series to ensure that the pressure of the municipal pipe network is not less than the set protection pressure (which can be a relative pressure). 0 pressure, when it is less than 0 pressure, it is called negative pressure) secondary pressurized water supply equipment. The core of the pipe network non-negative pressure superimposed water supply equipment is to prevent the generation of negative pressure during the operation of the secondary pressurized water supply system, to eliminate the impact of t...

Problems solved by technology

At present, the long-distance transmission pipeline network that delivers tap water from the water plant to the user is old and new. The aging of the pipeline network has caused some pollutants to form harmful components into the water. The deteriorating water environment often leads to a certain indicator of the secondary water supply water quality failing to meet drinking water. requirements, seriously affecting people's lives
