Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a split type wastewater treatment device. Background Art

[0002] Wastewater treatment is to treat wastewater using physical, chemical and biological methods to purify wastewater, reduce pollution, and even recycle and reuse wastewater to make full use of water resources. In the process of wastewater treatment, backwashing is often used to clean the filter to automatically remove impurities attached to the filter and improve filtration efficiency.

[0003] However, the backwash filter is generally not very effective in treating suspended solids, especially for high concentrations of suspended solids, which makes the filter cleaning uneven and incomplete, easily causing filter blockage, reducing filtration efficiency, and also increasing the difficulty of equipment maintenance.
