Example Embodiment

[0036]It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0037]The present invention provides an ecological system based on the EBR process, specifically, referencefigure 1 , The ecological system based on the EBR process includes: a pretreatment unit 1, an EBR biochemical treatment unit 2, and a post-treatment unit 3. The post-treatment unit 3 includes a secondary sedimentation tank 310, a high-density sedimentation tank 320, and a disinfection unit which are sequentially connected. Reoxygenation tank 330, further, referenceimage 3 The EBR biochemical treatment unit includes a plant system 6 for forming sewage up and down diversion, a root bionic filler 4, and an aeration device 5 to pass the plant system 6, root bionic filler 4, and aeration device in the EBR biochemical treatment unit 2. Device 5 improves the efficiency of sewage treatment and reduces operating costs while ens...

Abstract

The invention discloses an ecologicalization system based on an EBR process and a sewage treatment method based on surface water III emission, and the effluent quality can stably reach the III-class water quality standard of Environmental Quality Standard for Surface Water (GB3838-2002) according to the ecologicalization system based on the EBR process and the sewage treatment method based on surface water III emission. The system and the method are suitable for sewage treatment projects with high standard discharge requirements, the ecologicalization system based on the EBR process comprisesa pretreatment unit, an EBR biochemical treatment unit and a post-treatment unit, and a plant system used for forming up-and-down flow guide of sewage, a root system bionic filler and an aeration device are arranged in the EBR biochemical treatment unit. Therefore, the EBR biochemical treatment unit is used for improving the sewage treatment efficiency, the contact efficiency of organic pollutantsand microorganisms and the utilization rate of dissolved oxygen are improved, and further, the effluent quality can stably reach the III-class water quality standard of Environmental Quality Standardfor Surface Water (GB3838-2002).

Description

Technical field[0001]The invention relates to the field of sewage treatment, in particular to an ecological system based on an EBR process with high standard discharge requirements and a sewage treatment method based on surface water III discharge.Background technique[0002]At present, with the gradual implementation of the "Water Pollution Prevention and Control Action Plan", black and odorous water bodies will be gradually eliminated. However, the problem of eutrophication of water bodies has increasingly become a major water environmental problem that restricts economic and social development and the improvement of residents' living standards. At present, the commonly used process in sewage treatment plants is the treatment process of coarse grid + lifting pump tank + fine grid grid + grit tank + activated sludge tank + secondary sedimentation tank + disinfection tank + metering channel, but this process has high energy consumption, Disadvantages such as high operating costs and t...
