Integrated ultrafiltration water purification device

Abstract

The invention discloses an integrated ultrafiltration water purification device, comprising an integrated rack, an ultrafiltration membrane group, a water feed system, a water production system, a backwash system, an online cleaning and filtering device, a selective agent adding device and a control system, wherein the ultrafiltration membrane group comprises at least one ultrafiltration membrane pressure container with at least ten membrane filaments arranged on an inner plumb bob; the water feed system is communicated with raw water, is communicated with each ultrafiltration membrane pressure container, and is also communicated with the selective agent adding device and the online cleaning and filtering device in succession; the front and back ends of the water production system are communicated with each vertical ultrafiltration membrane pressure container and a water production tank respectively; the backwash system is communicated with backwash water and each vertical ultrafiltration membrane pressure container respectively; the control system is connected with other parts respectively. The integrated ultrafiltration water purification device disclosed by the invention is simple in structure, achieves general use and interchange of various membrane elements or pressure containers, is suitable for purification of various water qualities, is high in purification efficiency, and can effectively reduce the cost.

Description

Technical field [0001] The invention relates to a filtering device, in particular to a collection type ultrafiltration water purification device. Background technique [0002] At present, there are some integrated ultrafiltration water purification devices for industrial and municipal water treatment. However, most of these integrated ultrafiltration water purification devices are only suitable for the supply of domestic drinking water or the water demand of individual industrial fields. Sewage treatment for smaller companies. Due to the complexity of the ultrafiltration system itself, the integrated device is difficult to transport and install, and it is difficult to use simple technical means to meet various water quality requirements. How to add different pretreatment agents according to the difference in water quality, how to effectively prevent membrane fouling, and how to It is easy to complete the integrity inspection and judge the broken wire of the system. Therefore, th...

[0002] At present, there are some all-in-one ultrafiltration water purification devices for industrial and municipal water treatment, but most of these all-in-one ultrafiltration water purification devices are only suitable for household drinking water supply, or water demand in individual industrial fields Wastewater Treatment for Smaller Businesses

Due to the complexity of the ultrafiltration system itself, it is difficult to transport and install its integrated device, and it is difficult to use simple technical means to meet various water quality requirements. How to add different pretreatment agents according to the difference in water quality, how to effectively prevent membrane fouling, how to It is easy to complete the integrity test, judge the broken wire of the system, etc. Therefore, the technical limitations of these all-in-one ultrafiltration water purification devices limit their application in small and medium-sized water treatment projects in the industrial and municipal fields.

In addition, there is no uniform standard for ultrafiltration membrane elements at present. Commercially available ultrafiltration membrane elements are of different sizes, and there are various operating modes such as full flow, cross flow, backwash, positive wash, and air scrubbing, which lead to ultrafiltration membrane elements Bundled sales with ultrafiltration water purification devices bring limitations for later membrane replacement and increase the investment cost of the ultrafiltration membrane system in its entire life cycle
