Different quality water supply system

Abstract

The invention discloses a different quality water supply system which comprises a pretreatment system, a terminal water supply system, a return water quality guarantee system, a pure water tank and a high pressure pump, wherein the pretreatment system comprises a raw water pipeline, a raw water tank, a raw water pump, a multimedium filter and an active carbon filter that are communicated sequentially; the terminal water supply system comprises a water supply ultraviolet sterilizer, variable-frequency water supply equipment and a terminal water utilization pipeline that are communicated sequentially; the return water quality guarantee system comprises a return water security filter, a return water ultraviolet sterilizer and a return water precision filter that are communicated sequentially; and the return water precision filter is communicated with the pure water tank via a rear return water pipeline. The system has the benefits that the system is reasonable in structure, can effectively perform multistage filtering, sterilization and treatment on water, obtains the higher quality water, can perform water return on the terminal water utilization pipeline, allows the water to circularly flow, avoids dead water, can prevent secondary pollution and bacterial breeding and can effectively guarantee the water quality.

Description

technical field [0001] The invention belongs to the technical field of water supply systems, and in particular relates to a quality-based water supply system. Background technique [0002] With the development of my country's economy, the pace of urbanization is accelerating, the population density is becoming denser, the industry and agriculture are developing rapidly, the types and quantities of organic matter are increasing, and the random discharge of organic matter has caused serious water pollution and environmental pollution. The traditional production process of the water plant "coagulation-sedimentation-filtration-disinfection" can only remove about 20% of the organic matter in the water source, and the disinfection method mostly adopts filter disinfection, and the combination of chlorine and organic matter is easy to produce new carcinogens. From this point of view This traditional process has been far from meeting the needs of users. After centralized treatment, ...

The traditional production process of the water plant "coagulation-sedimentation-filtration-disinfection" can only remove about 20% of the organic matter in the water source, and the disinfection method mostly adopts filter disinfection, and the combination of chlorine and organic matter is easy to produce new carcinogens. From this point of view This traditional process is far from meeting the needs of users

After centralized treatment, tap water is sent to users through pipelines. Due to the aging of urban tap water pipe networks and inadequate maintenance of water tanks, secondary pollution will also occur, which will affect the quality of water.
