Sewage treatment equipment for environmental protection water treatment equipment

Sewage treatment of environmental protection water treatment equipment involves other uses and the use scope of membrane bioreactor MBR technology.

Our chemical raw materials products span photoinitiators, photninitiators, water treatment agents, pharmaceutical intermediates,pesticide intermediates and so on.

use

Buried sewage treatment equipment is suitable for domestic sewage in residential communities, hospitals, nursing homes, office buildings, shopping malls, hotels, restaurants, institutions, schools, military units, aquatic processing plants, livestock storage plants, dairy processing plants, and similar industrial organics. Wastewater, such as organic wastewater treatment in textile, beer, papermaking, leather making, food, chemical and other industries, the main purpose is to treat domestic wastewater and similar industrial organic wastewater to meet the requirements of reused water quality, and to make resources after wastewater treatment Chemical utilization.

Sewage treatment equipment uses membrane bioreactor (MembraneBioreactor, MBR for short) technology is a new process combining biological treatment technology and membrane separation technology, which replaces the secondary sedimentation tank in the traditional process, it can efficiently perform solid-liquid separation, Obtained stable reclaimed water for direct use. It can maintain a high concentration of microorganisms in the biological pool, the process has less residual sludge, and it can effectively remove ammonia nitrogen. The suspended solids and turbidity of the effluent are close to zero, and bacteria and viruses in the effluent are greatly Removal, low energy consumption, small footprint. In the 1970s, researches on membrane bioreactors for sewage and wastewater treatment have begun in the United States, Japan, South Africa and many countries in Europe. The water source is 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 sewage, office buildings, shopping malls, hotels, restaurants, institutions, schools, troops, factories and other domestic sewage and similar industrial organic wastewater, such as textile, beer, paper, leather, food, chemical and other industries deal with.

Process flow

Raw water → grid → regulation tank → lift pump → bioreactor → circulation pump → membrane module → disinfection device → reclaimed water storage tank → reclaimed water system

Process description

Sewage enters the regulating tank through the grille and enters the bioreactor through the lift pump. The PLC controller turns on the aerator for oxygenation. The effluent from the bioreactor enters the membrane separation processing unit through the circulation pump, and the concentrated water returns to the regulating tank. After rapid chlorination and disinfection (sodium hypochlorite, bleaching powder, chlorine tablets), it enters the reclaimed water storage tank. The backwash pump uses the treated water in the cleaning tank to backwash the membrane treatment equipment and backwash the sewage back to the regulating tank. The opening and closing of the lift pump is controlled by the water level in the bioreactor. The filtering operation and backwashing operation of the membrane unit can be controlled automatically or manually. When the membrane unit needs chemical cleaning operation, close the water inlet valve and sewage circulation valve, open the medicament washing valve and medicament circulation valve, start the medicinal liquid circulation pump, and perform the chemical cleaning operation.
