[0002] MVR high-efficiency sewage treatment device is a device that uses mechanical vapor compression technology to improve sewage treatment efficiency. MVR technology compresses the steam generated by evaporation to increase its temperature and pressure, and then reuses this high-temperature and high-pressure steam to heat the source water, thereby realizing energy recycling;

[0003] When the existing MVR high-efficiency sewage treatment device is in use, the filter needs to be placed above the water inlet tank of the MVR high-efficiency sewage treatment device to play a role in preliminary filtering of sewage. Usually, the filter is directly laid above the water inlet tank of the MVR high-efficiency sewage treatment device. When it needs to be recycled, the filter is directly rolled up and recycled and then laid again;

[0004] However, the corners of ordinary filters are prone to curling during use, and there is an obstruction from above when laying the filter, making it difficult to install quickly and easily. In addition, the lack of a fixed structure can easily cause the filter to move, making it impossible to filter sewage through the gaps in the corners. Utility Model Content
