Embodiment Construction

[0016] The water treatment system is composed of a raw water transfer device, a blower 1, a suction pump 3, an aeration device 7 arranged in a treatment tank 4, a hollow fiber membrane module 6 and a water level control device. The hollow fiber membrane module 6 is fixedly installed on the membrane support 5, the suction pump 3 is connected with the outlet pipe on the membrane support 5 by the pipeline 2; It is connected with an aeration device 7 made of a perforated pipe with small holes on the pipe wall. The compressed air is sprayed out from the small holes, and the sludge attached to the membrane is shaken off by aeration to reduce the clogging of the membrane pores. The above-mentioned membrane module 6 is connected by a plurality of hollow fiber membrane tubes (diameter of 270 microns, membrane tube wall aperture of 0.1 to 0.4 microns) and water collection pipes at both ends thereof. The outlet pipe on the support 5 is connected. The above-mentioned membrane support 5 ...

Abstract

A sewage treatment system comprises a suction pump, an aeration device and a water level control device which are arranged in a treatment tank, the sewage treatment system is characterized in that the aeration device is arranged below a membrane support, hollow fiber membrane components are fixedly arranged on the membrane support, the suction pump is connected with a water outlet pipe which is arranged on the membrane support by a pipeline, and a forced draft fan is connected with the aeration device by an air supply pipeline. A plurality of membrane supports are available, and a plurality of hollow fiber membrane components can be arranged on each membrane support; each hollow fiber membrane component is formed by communicating a plurality of hollow fiber membrane tubes and water collecting tubes. The water collecting tubes can be arranged at the both ends of each hollow fiber membrane tube and connected with the water outlet pipe on the membrane support. The system has the advantages of high water quality of processed water, space-saving property, simple structure, convenient maintenance and management and short construction period, and the like, and the system can treat sewage with the high concentration and can also purify tap water and groundwater.

Description

[technical field] [0001] The invention relates to a sewage treatment system, in particular to a hollow fiber membrane water treatment system. [technical background] [0002] Existing conventional water treatment methods include activated sludge method and membrane separation method, etc., which can only purify tap water, etc.; or can only treat low-concentration sewage, and the quality of the treated water is not high. Water treatment equipment takes up a lot of space, has a long construction period, and high maintenance and management costs. [0003] The notification number is CN1239007A In the invention patent specification, a "membrane treatment method and membrane treatment device" is disclosed, which is composed of a membrane device and a circulation tank arranged side by side. The device needs to repeatedly process the circulating fluid, and the quality of the treated water is high. However, its processing capacity is small and it is not suitable for industrial use. ...
