WSZ-F-4 integrated sewage treatment equipment——Process description

The sewage enters the regulating tank through the grid and then enters the bioreactor through the pump. The aeration machine is activated by the PLC controller for oxygenation, and the bioreactor enters the membrane separation treatment unit through the circulation pump. The concentrated water returns to the regulating tank, and the membrane separated water is quickly mixed and chlorinated (secondary, float, chlorine plate) before entering the reclaimed water storage tank. The backwash pump uses the treated water in the cleaning tank to backwash the membrane treatment equipment, and the backwash wastewater returns to the regulating tank. Control the opening and closing of the pump through the water level inside the bioreactor. The filtration and backwashing operations of the membrane unit can be controlled automatically or manually. When the membrane unit requires chemical cleaning operation, close the inlet valve and sewage circulation valve, open the chemical cleaning valve and chemical circulation valve, start the chemical circulation pump, and perform chemical cleaning operation.

It has the following functions:

·The membrane bioreactor adopts automatic control, which greatly reduces operating costs.

·When the water level in the bioreactor reaches a high level, the pump stops running, and when the water level drops to a low level, the pump automatically starts.

·Automatically turn on and off the circulating pump based on the water level in the reclaimed water storage tank.

·Automatically turn on and off the dosing pump, and the dosage can be adjusted as needed.

·Automatically run membrane cleaning and program.

·The motor is equipped with overcurrent and overload protection.

The existing reclaimed water reuse projects generally have problems such as poor treatment efficiency, high operating costs, and large facility areas, resulting in poor operation of the treatment facilities. Therefore, China's urban water treatment industry urgently needs economically applicable treatment processes and supporting equipment.

Working principle of small-scale sewage treatment equipment

MBR process characteristics

The application of membrane biological wastewater treatment technology in wastewater regeneration and utilization has the following characteristics:

Capable of solid-liquid separation, separating suspended, colloidal, and lost microbial communities from purified water in wastewater. The separation process is simple, the area is small, the water quality is good, and it can generally be reused without treatment.

Underground domestic sewage treatment equipment can beautify the environment without occupying ground space; The equipment is fully automated and does not require manual management; This device also has the characteristics of long service life and easy maintenance. Can be buried underground; Fully automatic control, no personnel management required; No sludge reflux; Easy to operate and maintain; Low noise and no odor; Long service life.
