Soft sheet film method waste water treatment intensive device

Abstract

The present invention relates to a soft sheet film method waste water treatment intensive device, which comprises a box case and cylinder type ultrafiltration film locking assemblies continuously overlapped by a plurality of circular-disc-shaped soft sheet plate type ultrafiltration films and locking sheets, wherein the box case is provided with a support frame, a back washing water storage tank, an electric control box, a raw water pump and a filter water pump are arranged on the support frame at the same time, the raw water pump and the filter water pump are positioned at the bottom of the support frame. The invention adopts a method of connecting a plurality of circular-disc-shaped soft sheet plate type cylinder type ultrafiltration film locking assemblies in parallel for forming an open type wide-flow-passage filter set body, a water and gas double-phase automatic cleaning device is designed for the ultrafiltration films, and the electric control box for automatically opening or closing the water pumps and water conveying and gas conveying pipeline control valves is arranged on the soft sheet film method waste water treatment intensive device. Thereby, the device has the advantages of large filter capacity, good cleaning effect of the ultrafiltration films, long service life, compact integral structure of the device, small area of the occupied ground, automatic operation, convenient and simple management and maintenance, high filtration precision and high efficiency. The invention particularly provides a good filter for the treatment of waste water containing a large number of fine particles with high viscosity and high filtration difficulty.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment devices, in particular to a water treatment device using an ultrafiltration membrane method. Background technique [0002] The ultrafiltration membrane water treatment device is currently the most convenient and effective device for pretreatment of wastewater. It has a simple structure, convenient operation, high quality effluent, and low investment and management costs. In particular, the patent application number 200910154165.3 newly developed by the applicant is the "plate-type ultrafiltration membrane locking assembly", which consists of a number of disc-shaped flexible plate-type ultrafiltration membranes and locking plates that are stacked arbitrarily and continuously to form a cylindrical ultrafiltration membrane locking assembly. , and then installed in the cylinder to form an ultrafilter. It is easy and quick to assemble and disassemble, easy to replace and maintain membran...

AI Technical Summary

Problems solved by technology

If the amount of wastewater treatment is large and multiple ultrafilters need to be used in parallel, the pipeline connection is complicated, manual operation is troublesome, and the floor area is large and the investment is high.
