Short process flow water treatment technology with hyperfiltration as core and integrated with multiple water purifying technologies

Abstract

The invention discloses a short-flow water treatment process for taking ultrafiltration as core and integrating multiple kinds of water purification technology into a whole. A flocculant is added to a raw water pipeline; after raw water has flocculation reaction in a flocculation pool, the raw water enters a membrane pool for precipitation and enters an ultrafiltration membrane system for ultrafiltration treatment; sludge immersed into a sludge condensation region of the membrane pool is condensed and is discharged out of the pool by a sludge discharge pipeline; and water filtered by the ultrafiltration membrane system passes through a water producing pipeline and enters a clean water pool. The process has the advantages of short flow, small occupied area, convenient operation and management, low operating cost, good quality of outlet water, and the like. After the raw water is treated through the water purification process provided by the invention, biological safety of the outlet water is greatly improved and fully reaches or even exceeds New National Health Standard of Drinking Water (GB5749-2006).

Description

Technical field: [0001] The invention belongs to the technical field of water supply purification, in particular to a short-flow water treatment process with ultrafiltration as the core and integrating various water purification technologies. Background technique [0002] At present, the water purification process is mainly based on coagulation-sedimentation-filtration-disinfection. A certain amount of coagulant is added to the raw water to form flocs. After the flocs are removed by sedimentation, sand filtration is performed to further remove the remaining suspended The effluent is disinfected to complete the purification process. The process is long, complex in management, large in area, high in investment cost and high in operation cost. At the same time, this process cannot effectively remove cryptosporidium, giardia and other harmful organisms to the human body, and there are certain biological safety hazards. However, due to the aggravation of water pollution, the im...

Problems solved by technology

The process is long, complex in management, large in area, high in investment cost and high in operation cost

At the same time, this process cannot effectively remove cryptosporidium, giardia and other harmful organisms to the human body, and there are certain biological safety hazards

However, due to the aggravation of water pollution, the improvement of people's living standards and the upgrading of national water quality standards, this process can no longer fully meet the requirements of water purification.
