Membrane bioreactor environmental protection standards solicit opinions

The Ministry of Environmental Protection recently announced two drafts of national environmental protection standards, including membrane bioreactors, to solicit opinions from the public.

These two standards are "Technical Requirements for Environmental Protection Products Membrane Bioreactor" and "Technical Requirements for Environmental Protection Products Hollow Fiber Membrane Bioreactor Assembler", formulated by the Department of Science and Technology Standards of the Ministry of Environmental Protection, and drafted by China Environmental Protection Industry Association and Tianjin Xingyuan Environmental Technology Engineering Co., Ltd.

The national standard for membrane bioreactors for comments stipulates the requirements for manufacturing and processing, material selection, component configuration, electrical safety, and effluent water quality of membrane bioreactors. It is a guiding standard and is suitable for domestic sewage and biochemically treated industrial wastewater. Membrane bioreactors used in reuse projects. The draft of the national standard for hollow fiber membrane bioreactor assembly stipulates the technical requirements, test methods and inspection rules of the hollow fiber membrane bioreactor assembly, which is applicable to the hollow fiber membrane bioreactor assembly for the treatment of domestic sewage, and also applies to For other sewage treatment equipment assemblies whose biochemical properties are close to those of domestic sewage, the applicable scale is 20-2000 cubic meters per day.

It is understood that the membrane bioreactor is a new type of water treatment technology that combines membrane separation technology and biotechnology. It uses membrane separation equipment to trap the activated sludge and macromolecular organic substances in the biochemical reaction tank, saving the secondary sedimentation tank. It is one of the most promising new technologies for wastewater treatment and an effective water reuse technology for municipal and industrial wastewater.

In recent years, domestic sewage membrane treatment technology has made rapid progress, and Beijing Moyu Shenda Environmental Technology Co., Ltd., Tianjin Motianmo Technology Co., Ltd., Jiangxi Jindalai Environmental Protection Co., Ltd., and Sanda Membrane Technology (Xiamen) Co., Ltd. have emerged. And Shanghai Snap Membrane Technology Co., Ltd. and a group of leading membrane bioreactor development and production enterprises. The two national standards released this time will fill the gaps in this field and help regulate the development of this emerging technology field.
