Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, and more specifically relates to a submerged hollow fiber membrane element, a membrane module, a membrane module system and a preparation method. Background technique [0002] With the rapid development of my country's economy, the consumption of water resources has doubled. On the one hand, it has caused a shortage of water resources, and at the same time, it has also increased the generation of sewage, which has increased the pressure on sustainable development of society and the environment. For this reason, relevant parties A large amount of money has been invested in the treatment of sewage and its resource reuse. The complexity of water source pollution makes the contradiction between actual water source water quality and water quality demand more and more prominent, thus putting forward a higher and newer urgent demand for water quality purification treatment and technical ...
