Problems solved by technology

[0003] However, the existing research on the materials of suspended biological carriers still has the following shortcomings: (1) The selection and combination of materials do not consider the different types of microorganisms in sewage, so the existing biological carriers cannot absorb various microbial populations in sewage, nor can they be compared. Thoroughly treat sewage; (2) The material distribution is single, and there is no staggered distribution in space according to the habits of different microbial populations, so that the space utilization rate of the material is not high; although the biological carrier described in patent 03150250.4 is added with microbial dry powder, but It is not added in different areas according to the different living habits of microbial populations, so it cannot effectively adsorb multiple populations of microorganisms

Abstract

This invention relates to a suspended microbe carrier that is suitable for microbes. One unit of the suspended microbe carrier is composed of an outer ring, a middle ring, an inner ring and a supporting rod. The supporting rod connects the outer, middle and inner rings. Multiple units are uniformly placed and circumferentially supported by the supporting rods to constitute a porous structure. The polymeric material of the inner ring is spray-coated with anaerobic microbe dry powder and inorganic powder. The polymeric material of the middle ring is spray-coated with anaerobic and aerobic microbe dry powder and inorganic powder. The polymeric material of the inner ring is spray-coated with aerobic microbe dry powder and inorganic powder. The materials of the carrier are suitable for the microbes in wastewater. Besides, the material spatial distribution is suitable for the living habits of different microbes. Therefore, the carrier has a high spatial utility and a good wastewater treatment effect.

Description

technical field [0001] The invention relates to a biological carrier for water treatment, and more specifically refers to a suspended biological carrier whose material is suitable for the type and habit of microorganisms. Background technique [0002] Suspended biological carriers play an important role in sewage biological treatment. At present, there are many suspended biological carriers in practical application. Most biological carrier products have made many improvements in structure, but relatively few improvements have been made in carrier materials. In-depth research on suspended biological carriers now shows that the material of the biological carrier directly affects the adhesion of the biological carrier to microorganisms. Some studies have improved the material of the biological carrier. For example, Chinese patent 01129834.0 discloses a plastic with an elastic and hydrophilic surface Filler, the material is composed of commonly used p...
