Problems solved by technology

[0014] However, existing biofilm reactors also have deficiencies: the water treatment structures composed of fillers and biofilms on their surfaces are easy to block; aerobic bacteria still need to be aerated into the reactor, which consumes a lot of energy; , anaerobic bacteria generally cannot coexist and need to be treated separately, etc.

Abstract

The invention relates to a water treatment biological membrane reactor. The water treatment biological membrane reactor is mainly composed of a substrate and an attachment adhered to the surface of the substrate, the substrate is of a plane mesh structure, and the attachment on the surface of the substrate is expanded after water absorption, so that the mesh holes of the substrate are fully filled to form a membrane which water cannot directly penetrate through but organic matter in the water can pass through in a diffusion mode; the sizes of the mesh holes of the substrate are smaller than or equal to a critical size, wherein the critical size is a size in which the expanded attachment can be just limited by the mesh holes and cannot be washed out and stripped by running water, the substrate is made of a high molecular material or a high molecular composite material or an inorganic nonmetallic material or an inorganic nonmetallic composite material or a compound of the high molecular material and the inorganic nonmetallic material, and the attachment is a macromolecular substance. The water treatment biological membrane reactor can effectively purify waste water, has the advantages of being not likely to be blocked, low in energy consumption and low in cost, and has a very good industrialized popularization advantage.

Description

Technical field [0001] The invention belongs to the field of sewage treatment and relates to a water treatment biofilm reactor. Background technique [0002] In recent years, with the rapid development of my country’s economy and the continuous growth of population, a large number of pollutants have been discharged into rivers and lakes and other surface water ecosystems, resulting in the destruction of the ecological environment of the river basin and severely restricting the sustainable development of the economy and society. Affect people's quality of life. The continuous development and engineering application of sewage treatment technology has become an essential part of maintaining the sustainable development of society and economy. Various wastewater treatment processes based on the principles of physics, chemistry, and biology are emerging. Among them, biological treatment technology is the most widely used and has become the mainstream process for urban sewage and organi...
