Integrated water purification device and water purification method

Abstract

The invention relates to an integrated water purification device and a water purification method. The device comprises a flocculation basin, an inclined plate sedimentation basin and a non-overflowing double-layered filter material filtering tank which are sequentially connected in series, wherein the filtering tank comprises a filter material layer, a supporting layer, a water distribution and gas distribution assembly and a water distribution water channel which is vertically arranged along the middle part of the filtering tank; the water distribution and gas distribution assembly comprises a water collection pipe row which is horizontally arranged, and a vertical pipe row which is vertically arranged; the upper ends of all vertical pipes are communicated with water collection pipes in the water collection pipe row and the lower ends of all the vertical pipes are communicated with the water distribution water channel; a water discharging hole is formed in the bottom of each water collection pipe, and an air exhausting hole and a washing air hole are sequentially formed in the middle part and the top of each water collection pipe; and an air inlet small hole is formed in the lower middle part of each vertical pope. According to the integrated water purification device and the water purification method, the problems that a filtering head of a double-layered filter material filtering tank is easy to block, a filter material cannot be washed, a mud ball is deposited, the filtering material is lost, the construction cost is high, the maintenance is complicated ant the like can be solved; the construction period is short, a land is saved and the construction cost is low; and the water supply requirements of countryside villages and towns, and industrial and mining enterprises, and beauty spots, which are far away from cities can be met.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to an integrated water purification device and a water purification method. Background technique [0002] The current pollution of drinking water sources in my country is characterized by a wide range of pollution and serious local pollution. Therefore, strategically, my country's drinking water decontamination technology can be developed from two different levels: one is to develop an economical micro-pollution technology that is suitable for water plants in my country and is easy to popularize and apply; The second is to develop advanced treatment technology, focusing on the treatment of source water from local heavily polluted water sources or for use in situations with high water quality requirements. Advanced treatment technology is to use some unconventional technical means, such as advanced oxidation technology, membrane treatment technology and other measures to s...

AI Technical Summary

Problems solved by technology

[0004] Although the existing water purifiers have their own advantages, there are still certain disadvantages, mainly in the fact that the filter material is easy to harden, the filter head and filter are easy to block, the flocculation effect is poor, the anti-risk ability is weak, and the raw water quality changes greatly. Small bearing capacity, frequent backwashing, etc.
