Embodiment Construction

[0036] The invention provides a large specific surface area particle biological enhanced water treatment system, which includes a biological enhanced treatment subsystem, a continuous dynamic sand filter subsystem, a dynamic membrane separation and purification subsystem, a biological enhanced treatment subsystem, and a continuous dynamic sand filter subsystem , and the dynamic membrane separation and purification subsystem are connected in turn through water pipes to form a circulating water treatment system; the bio-enhanced treatment subsystem includes raw water and bio-enhanced large specific surface area particles, and the biochemical water after biochemical treatment by the bio-enhanced treatment subsystem carries a large specific surface area. The surface area particles enter the continuous dynamic sand filter system, and the large specific surface area particles in the water are filtered in the continuous dynamic sand filter system and returned to the biological enhanced...

Abstract

The invention relates to a biological strengthening treatment water system for large specific surface area particles, which comprises a biological strengthening treatment subsystem, a continuous dynamic sand filtration subsystem and a dynamic membrane separation and purification subsystem, the subsystems are successively connected through water pipes to form a circular water treatment system, thebiological strengthening treatment subsystem comprises raw water and biological strengthened large specific surface area particles, a bio-solution after biochemical treatment carries large specific surface area particles and enters into the continuous dynamic sand filtration subsystem, large specific surface area particles in water is filtered and returned in the biological strengthening treatment subsystem, the filtered sand filtration liquid enters in the dynamic membrane separation and purification subsystem, impurities in water are separated by a dynamic membrane formed by large specific surface area particles, partial large specific surface area particles are conveyed in the biological strengthening treatment subsystem after back flushing, the other part of the large specific surfacearea particles and newly added large specific surface area particles newly form the dynamic membrane, so that the technical problem in the prior art that large specific surface area particles can notbe separated from water is solved.

Description

technical field [0001] The invention relates to a water treatment system, in particular to a biologically enhanced water treatment system for particles with a large specific surface area. Background technique [0002] The biochemical treatment of sewage / drinking water, especially the activated sludge technology is a relatively mature water treatment technology nowadays, and the water quality treated by the biofilm method is relatively good; and the particles with large specific surface area (such as diatomaceous earth, activated carbon, zeolite) are used as carriers. Biological bacteria micelles are attached to the surface to form a bioreactor. This method combines the characteristics of activated sludge and biofilm methods, and has the characteristics of high treatment efficiency and little influence on the quality of effluent water and fluctuations in water volume. [0003] However, there are also problems in the practical application of the process method of biologically ...
