Embodiment

[0022] Example: as attached figure 1 As shown in the figure, a sewage treatment improvement system based on MBBR functional carrier materials, including a filter area, anaerobic area, anoxic area, aerobic area, flocculation area, sedimentation area and drainage area, is characterized in that: An anaerobic suspension carrier is provided in the anaerobic zone, an anoxic suspension carrier is provided in the anoxic zone, an aerobic suspension carrier is provided in the aerobic zone, the anaerobic zone, the anoxic zone and the aerobic zone There are carrier filters on the outlet pipes in the district.

[0023] In the prior art, only one set of carrier is used in the anaerobic zone, anoxic zone and aerobic zone of the AAO method, and there are biofilms of anaerobic bacteria, anoxic bacteria and aerobic bacteria on the carrier, so there are separate Bacteria compete with each other, and the biofilm flows with the sewage. For example, the biofilm of anaerobic bacteria is the competi...

Abstract

The invention belongs to the technical field of sewage treatment, and especially relates to a sewage treatment upgrading reconstruction system based on MBBR functional carrier materials. The three MBBR functional carrier materials have positive charges with different intensities, and are respectively used for attracting anaerobic bacteria, anoxic bacteria and aerobic bacteria with different numerical negative charges, and water filtration, carrier interception and bio-membrane adhesion reduction of positively charged carrier filter screens are adopted to achieve the targeted sewage treatment effect of bio-membranes on the carriers in three tanks of AAO. The three carriers are specifically used for the three different bacteria, so competition among the bacteria is avoided, the dominant bacterium attached biomasses in different treatment tanks are large, the charge attraction and adhesion effect mode is good, and the AAO process sewage indicator reduction effect is good.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a system for improving and transforming sewage treatment based on MBBR functional carrier materials. Background technique [0002] MBBR functional carrier material is different from the existing PE or PP material carrier, which has the advantages of large specific surface area and large amount of biofilm eventually formed, which can greatly improve the efficiency of microbial treatment of sewage. But on the other hand, the existing functional carrier materials only increase the specific surface area through the improvement of the shape structure, which can be used from 700-1000m 2 / m 3 Value increased to 2000 m 2 / m 3 level, but this still cannot meet the higher sewage treatment requirements of surface quasi-class IV water. [0003] The patent publication number is CN105129989A, and the Chinese invention patent with the publication date of 2015.12.09 disc...
