Tube-type sewage water micro-filter processing equipment

Abstract

The present invention relates to a pipe type sullage micro-filtration processing device, comprising a reaction groove, a concentration groove equipped next to the said reaction groove, a circulating power pump, a micro-filtration membrane pipe adopting cross-flow filtration and a cleaning buffer column, wherein micro-filtration membrane cross-flow filtration technology and pipe connection technology coordinating with cleaning buffer column and air intake valve group are adopted in order to implement automatic backwashing function through joint operation; the invention adopts reaction groove and concentration groove for sullage pretreatment through overflow mode cooperation, so as to guarantee water yielding effect and water yielding flux of system.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a tubular sewage microfiltration treatment equipment with microfiltration membrane filtration and backwashing functions; it is mainly used to remove pollutants in industrial wastewater, such as printed circuit boards, metal Polishing, electronic manufacturing, automation industry, aviation, steel, semiconductor and electroplating and other industrial fields. Background technique [0002] Traditional industrial wastewater treatment systems generally have limited bearing capacity for suspended solids in sewage, poor impact load resistance, and cannot effectively maintain the quality of produced water. Corresponding polymers need to be added, and it takes a period of time to reach a stable working condition after startup, and Still need multi-media filter for further processing, so very loaded down with trivial details, is unfavorable for operation. At present, in the field of water pur...

Problems solved by technology

[0002] Traditional industrial wastewater treatment systems generally have limited bearing capacity for suspended solids in sewage, poor impact load resistance, and cannot effectively maintain the quality of produced water. Corresponding polymers need to be added, and it takes a period of time to reach a stable working condition after startup, and Multi-media filter is still required for further processing, which is very cumbersome and not conducive to operation

At present, in the field of water purification, there are often microfiltration (MF) treatment methods. This treatment uses a semi-permeable membrane method to achieve a low-pressure separation technology that separates large particles of melt in the solution, and further uses cross-flow technology (TMF ) substances that can be trapped on the surface of the membrane (such as large particles) will not stay on the outer surface of the membrane, such as Chinese patent ZL03235053.8 "an external pressure tube microfiltration membrane water treatment device", which is suitable for domestic drinking water The pretreatment of treatment cannot be applied in industrial sewage treatment, so in view of this, it is necessary for the applicant to propose a pipeline type sewage circulation sewage filtration treatment system
