Novel building zoning, pressure division and quality division water supply process

Abstract

The invention discloses a novel building zoning, pressure division and quality division water supply process. The process comprises a secondary water supply system, a pipe network system and a water purification system; the process comprises the following steps that a) raw water is pretreated by the secondary water supply system, and the raw water is firstly subjected to disinfection, filtration and secondary pressurizing and then is conveyed to a domestic water supply pipeline through a pipeline of the pipe network system; b) a plurality of branch pipelines are arranged on one side of the domestic water supply pipeline, and control valves are arranged on the branch pipelines and used for conveying domestic water to domestic water pipelines of all users; and c) the other end of the domestic water supply pipeline is connected with water purification equipment of the water purification system, the output end of the water purification equipment is connected with a direct drinking water pipeline through the pipe network system, the direct drinking water pipeline is connected with a water distributor, and direct drinking water is conveyed to an indoor direct drinking water faucet of a user through the water distributor. According to the process, an economical, effective and convenient-to-manage water supply mode for supplying the domestic water and the drinking water by means of different pipelines is finally realized.

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to a novel partitioning, pressure-dividing and quality-divided water supply process. Background technique [0002] In the current quality-based water supply scheme, domestic water supply (including domestic drinking water) and direct drinking water are implemented by different entities, the jurisdiction of equipment and facilities is not unified, and the construction unit attaches great importance to the investment in drinking water facilities. Direct drinking water generally exists as an independent facility for domestic water supply, which leads to additional expenditures for repeated construction, operation and maintenance in some areas to improve water quality for users, and thus forms a solution for water supply by quality. Generally speaking, there will be the following disadvantages: [0003] 1. Using the scheme of integrated water purification equipment, from the urban pipe...

Problems solved by technology

[0002] In the current quality-based water supply scheme, domestic water supply (including domestic drinking water) and direct drinking water are implemented by different entities, the jurisdiction of equipment and facilities is not unified, and the construction unit attaches great importance to the investment in drinking water facilities. Direct drinking water generally exists as an independent facility for domestic water supply, which leads to additional expenditures for repeated construction, operation and maintenance in some areas to improve water quality for users, and thus forms a solution for water supply by quality. Generally speaking, there will be the following disadvantages:

[0003] 1. Using the scheme of integrated water purification equipment, from the urban pipe network to water purification equipment to users, professional units can be entrusted to maintain the equipment, but it will inevitably lead to repetitive costs of pressurization and pipelines (including construction and operation and maintenance) investment;

[0004] 2. The domestic or commercial water inlet equipment purchased by users themselves is not satisfactory in terms of direct drinking water experience due to inconsistent equipment standards, high cost of equipment replacement consumables, and lack of professional equipment maintenance experience. , and even cause water quality problems due to improper management

[0005] Of the above two modes, the second mode is more common, and it is a common way to realize direct drinking water in domestic water. However, due to the lack of professional and effective maintenance and management of equipment, the penetration rate of direct drinking water is not high or the use of rate is not high
