Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and more specifically, to a baffle-type wastewater treatment and purification device. Background Technology

[0002] The baffle-type wastewater treatment and purification device is a high-efficiency water treatment equipment designed based on the principle of multi-stage baffle reaction. By setting up a staggered baffle structure in the reaction tank, it forces the water flow to form a continuous zigzag flow path, thereby extending the contact time between wastewater and the treatment medium (such as packing, microbial film or agents), enhancing mass transfer efficiency and optimizing the hydraulic retention time distribution. It can be widely used in domestic sewage, industrial wastewater and rural decentralized sewage treatment scenarios, and is especially suitable for engineering needs that require both small footprint and improved treatment efficiency.

[0003] Traditional baffle-type wastewater treatment and purification devices typically use multiple baffles to force water flow and form a continuous baffle path. However, during the baffle process, especially at the turning points, impurities in the wastewater are most likely to accumulate and be filtered. However, existing baffles are only used to form baffles to increase contact time, neglecting the flow purification and cleaning of wastewater during the baffle process. This can easily lead to a large accumulation of impurities on the top of the subsequent wastewater treatment packing, causing blockage. Utility Model Content
