Description

Technical Field

[0001] This utility model relates to the field of water treatment and reuse technology, specifically a membrane-integrated water treatment and reuse environmental protection equipment. Background Technology

[0002] Membrane-integrated water treatment and reuse environmental protection equipment uses membrane modules to precisely remove pollutants such as suspended solids, bacteria, and ions from water, purifying non-clean water such as rainwater, domestic sewage, and industrial wastewater, and producing water that meets reuse standards for applications such as greening irrigation and industrial water replenishment. The equipment has a high degree of integration, a small footprint, and stable water output, realizing a closed loop from water treatment to water reuse, reducing water waste and pollution emissions.

[0003] Among existing membrane-integrated water treatment methods, the curtain-type hollow fiber membrane module is widely used for domestic and light industrial wastewater treatment due to its large filtration area and low cost. However, in actual operation, suspended solids, colloids and macromolecular organic matter in wastewater are prone to adhere to the surface of the membrane fibers. After long-term filtration, impurities can accumulate and clog the membrane pores, thereby weakening the filtration effect of the device. To address this, we propose a membrane-integrated water treatment and reuse integrated environmental protection equipment. Utility Model Content
