What are the performance and characteristics of domestic sewage treatment equipment?

After passing through the screen, wastewater enters the equalization tank and then is pumped into the biological reactor. Oxygen is supplied by an aeration machine activated by a PLC controller. The effluent from the biological reactor enters the membrane separation unit via a circulation pump. Concentrated water returns to the equalization tank. The water separated by the membrane is disinfected using rapid mixing chlorination (sodium hypochlorite, bleaching powder, chlorine tablets) before entering the reclaimed water storage tank. A backwash pump uses treated water from the cleaning tank to backwash the membrane treatment equipment, and the backwash wastewater returns to the equalization tank. The operation of the lift pump is controlled by the water level in the biological reactor. The filtration and backwashing operations of the membrane unit can be controlled automatically or manually. When the membrane unit requires chemical cleaning, close the inlet valve and wastewater circulation valve, open the chemical washing valve and chemical circulation valve, and start the chemical circulation pump to perform the chemical cleaning operation.
Performance characteristics of domestic wastewater treatment equipment:
1. High purification rate and good effluent quality. Due to the separation function of the membrane, the equipment has powerful filtration capabilities, and direct reuse is possible without three-stage treatment.
2. Small footprint.
3. Cost-effective operation. The equipment has low power consumption and does not require the addition of flocculants, reducing operating costs.
4. Wide range of system applications.
4. Strong system shock resistance and wide adaptability. Prevents the loss of various microbial groups, is beneficial to the growth of slowly growing bacteria (nitrifying bacteria, etc.), increases the residence time of some macromolecular, difficult-to-degrade organic matter, and facilitates their decomposition, thus ensuring the smooth progress of various metabolic processes in the system.
5. High efficiency, with virtually no sludge discharge.
6. High degree of automation, requiring no special supervision, operating 24 hours a day, only requiring maintenance at fixed times.
7. Modular design. Zero-discharge domestic wastewater equipment is easy to freely combine according to water volume. Due to its high level of integration, MBR has formed standardized and serialized standard equipment, which users can combine and install according to project needs.
The company mainly produces various dust removal, desulfurization, denitrification, VOCs waste gas purification, wastewater treatment, noise reduction, complete sets of industrial electrical control systems and equipment, and researches and develops waste gas, wastewater, waste residue, and noise treatment equipment.
