Integrated water purifying facility for centralized water supply to villages and towns

Abstract

The invention discloses an integrated water purifying facility for centralized water supply to villages and towns. The integrated water purifying facility comprises a water inlet pipe, a water outlet pipe, a drug mixing and adding system, a main body facility and a back flushing system, wherein the drug mixing and adding system comprises a coagulant adder, a dosing pipe and a static hydraulic mixer; the static hydraulic mixer is mounted on the water inlet pipe; the coagulant adder is connected with the dosing pipe; an outlet of the dosing pipe is connected with the water inlet pipe and located in front of the static hydraulic mixer; the main body facility comprises a flocculation precipitation system, a filtering system and a sludge discharge system; the flocculation precipitation system and the filtering system are arranged in a hollow cylinder; a ring partition wall is arranged in the hollow cylinder; the ring partition wall divides the hollow cylinder into an outer circle area and an inner circle area; the flocculation precipitation system is arranged in the outer circle area; the filtering system is arranged in the inner circle area; an outlet of the water inlet pipe is located in the flocculation precipitation system; the flocculation precipitation system is communicated with the filtering system and the sludge discharge system; and the filtering system is communicated with the water outlet pipe. The integrated water purifying facility disclosed by the invention has the advantages of strong adaptability to the change of raw water quality, good yielding water quality, small floor area, low construction investment and simple operation management.

Description

technical field [0001] The invention belongs to the technical field of water supply for villages and towns, and specifically relates to an integrated water purification facility for centralized water supply for villages and towns where the water supply source is surface water. Background technique [0002] At present, most villages and towns in my country have water supply problems such as insufficient drinking water sources and substandard drinking water quality, which directly affect the normal life of residents in villages and towns. With the continuous development of my country's economy and the continuous improvement of national living standards, the demand for drinking water and the quality of water supply by village and town residents are also increasing. Therefore, improving the water supply conditions of villages and towns, optimizing the water purification technology of villages and towns and improving the quality of water supply are urgent problems to be solved in...

AI Technical Summary

Problems solved by technology

First of all, most integrated water purification facilities use conventional flocculation structures such as folded plates and grids in the flocculation stage. In order to make the facility structure compact and save space, integrated water purification facility manufacturers often reduce the design volume of the flocculation zone, which is very difficult. It is difficult to meet the requirements of conventional flocculation reaction time, resulting in insufficient flocculation reaction, which reduces the probability of particle collision and makes it difficult to coagulate, which directly affects the sedimentation effect, which eventually increases the filter load and shortens the filtration cycle.

Secondly, this type of water purification facility is manufactured in a rectangular or square shape for the convenience of production and processing. This kind of equipment has poor hydraulic conditions and is prone to produce dead water areas, which in turn affects the treatment effect.

Thirdly, most of the integrated water purification facilities on the market are assembled on-site from finished products or parts, and the manufacturing and transportation costs are high, and the operation and maintenance of the facilities require technical personnel with certain professional skills, especially for some facilities far away from the city. The development of relatively backward villages and towns can hardly bear the project investment and management and operation costs

[0006] Therefore, it is of great significance to develop an economically feasible integrated water purification facility for centralized water supply in villages and towns to solve the problem of water supply safety in villages and towns that use surface water as the water supply source.
