Drinking water treatment device based on ultrafiltration device

Abstract

The invention discloses a drinking water treatment device based on an ultrafiltration device, which comprises a primary lift pump, a coagulation sedimentation basin, an ultrafiltration device and a clean water basin. A huge sand filtering basin in the traditional water making process is omitted. The water outlet of the primary lift pump is connected with the water inlet of the coagulation sedimentation basin. The water outlet of the coagulation sedimentation basin is connected with an adsorption reaction basin through a pipe. The water outlet of the adsorption reaction tank is connected with the water inlet of the ultrafiltration device through a water ultrafiltration pump. The water outlet of the ultrafiltration device is connected with the water inlet of the clean water basin. The drinking water treatment device based on the ultrafiltration device disclosed by the invention has the advantages that the filtering accuracy is high, the turbidity of outlet water is low and the quality of the outlet water is obviously promoted; various pollutants such as soluble organic matters, bacteria, viruses and the like can be removed from the water; the chlorine dosage can be reduced, the generation of chlorinated byproducts is avoided, the safety of drinking water is guaranteed, the taste of the water is further improved and the requirement of raising drinking water standards is satisfied; and the equipment investment is lower than the equipment investment of the traditional drinking water treatment process.

Description

technical field [0001] The invention relates to drinking water treatment technology, in particular to a drinking water treatment device based on an ultrafiltration device. Background technique [0002] At present, domestic conventional water production processes are traditional processes, namely coagulation, sedimentation, filtration (sand filtration), and disinfection. With the continuous deterioration of surface water quality and the improvement of drinking water quality standards, traditional water production processes have gradually found it difficult to fully meet the requirements of drinking water quality standards. [0003] In the traditional water production process, the sand filtration process occupies a large area, has high requirements on the water distribution system, and has low filtration accuracy, and the turbidity of the effluent is about 1NTU. In engineering applications, in addition to ensuring strict design and installation conditions, regular maintenance...

AI Technical Summary

Problems solved by technology

[0011] At present, there are many single or combined research results on the advanced treatment of water by activated carbon and ultrafiltration technology in China, but most of them are applied to the traditional drinking water treatment process as a link to improve and guarantee water quality. On the one hand, the investment cost is increased, and on the other hand It also brings higher operating costs, which makes the development of ultrafiltration process in the field of drinking water treatment slow, which affects the application of ultrafiltration process in this field.
