Integrated Wastewater Treatment Equipment with MBR Treatment Process

Introduction

Membrane Bioreactor (MBR) technology is a new process combining biological treatment technology and Membrane separation technology, replacing the traditional process of secondary sedimentation tank, which can efficiently carry out solid-liquid separation, and obtain stable medium water for direct use. And can maintain a high concentration of microbial biomass in the biological tank, the process of less residual sludge, very effective removal of ammonia nitrogen, effluent suspended solids and turbidity close to zero, out of the water bacteria and viruses are greatly removed, low energy consumption, small footprint. In the 1970s, membrane bioreactor (MBR) has been used in the research of sewage and wastewater treatment in the United States, Japan, South Africa and many European countries. Its water source comes from domestic sewage (such as shower drainage, toilet drainage, laundry drainage, kitchen drainage, toilet drainage, etc.) and cooling water.

Scope of application

Suitable for residential areas, office buildings, shopping malls, hotels, restaurants, agencies, schools, troops, factories and other domestic sewage and similar industrial organic wastewater treatment, such as textile, beer, paper making, leather, food, chemical and other industries of organic sewage treatment.

Process flow

Raw water → grid → regulating pool → lifting pump → bioreactor → circulating pump → membrane assembly → disinfection device → medium water storage tank → medium water system

MBR process characteristics

The application of membrane biological wastewater treatment technology in wastewater recycling has the following characteristics:

(1) Can efficiently carry out solid-liquid separation, the suspended substances in wastewater, colloidal substances, biological unit loss of microbial flora and has been separated from the purified water. The separation process is simple, covers an area of small, the effluent water quality is good, generally does not need to go through three levels of treatment can be reused.

(2) The biomass in the biological treatment unit can be maintained at a high concentration, which greatly improves the volume load. Meanwhile, the high efficiency of membrane separation can greatly shorten the hydraulic residence time of the treatment unit and reduce the area of the bioreactor.

(3) Because it can prevent the loss of various microbial flora, it is conducive to the growth of bacteria with slow growth rate (nitrifying bacteria, etc.), so that various metabolic processes in the system can proceed smoothly.

(4) Make the residence time of some macromolecules difficult to degrade organic matter become longer, which is conducive to their decomposition.

[5] membrane treatment technology and other filtration and separation technology, in the long-term operation process, membrane as a filter medium blockage, membrane through water running time and gradually decreased effective backwash and chemical cleaning can slow down the decline of membrane flux, maintain the effective service life of MBR system.

(6) MBR technology applied in urban sewage treatment, because of its simple process, convenient operation, can realize automatic operation management.
