It uses ultrafiltration or microfiltration membrane separation technology to replace the secondary sedimentation tank and conventional filtration unit of the traditional activated sludge method, so that the hydraulic retention time (HRT) and sludge age (STR) are completely separated. This is an efficient and economical sewage resource technology with efficient solid-liquid separation capabilities. Not only is the effluent water quality good, the suspended solids and turbidity are close to zero, but it can also intercept biological pollutants such as Escherichia coli. And because the effluent water quality is significantly better than the traditional sewage treatment process, the treated water can be directly reused, and it has a wide range of application prospects.

[0003] The rigid flat membrane is assembled to the flat membrane support to form a flat membrane assembly. The existing rigid flat membrane assembly is customized with different types of stainless steel membrane supports according to different water volumes and membrane pool sizes for different projects. Different projects require constant changes in size, and the processing is cumbersome and the manufacturing cycle is long. During transportation and storage, since the membrane support is welded from an integral frame, it occupies a large space, greatly increasing transportation costs and storage land, and it is impossible to mass-produce and store a certain amount of goods, resulting in low production efficiency and long delivery time, which is not conducive to the development of the enterprise.

[0004] Therefore, it is necessary to provide an assembled membrane support for a rigid flat membrane to solve or at least partially solve the above problems. Utility Model Content
