Distributed type sewage treatment system

Abstract

The invention relates to the technical fields of sewage collection, discharge and sewage treatment, and especially relates to a distributed type sewage treatment system which includes a tree-shaped sewage pipe network, a plurality of sewage treatment base stations in a distributed type arrangement along the tree-shaped sewage pipe network, and sewage treatment devices arranged in the sewage treatment base stations. Compared with the prior art, the distributed type sewage treatment system can significantly save land resources, save the cost of project construction, realize modularization, automation and intelligent management of sewage collection, discharge and sewage treatment and realize sewage classification treatment.

Description

technical field [0001] The invention relates to the technical field of sewage collection, discharge and sewage treatment, in particular to a distributed sewage treatment system technology. Background technique [0002] The existing sewage collection, discharge and sewage treatment are carried out separately. The sewage collection and discharge are mainly operated by the drainage company, following the technical route of classified collection and control of discharge. The sewage treatment is mainly operated by the sewage treatment plant, following the centralized treatment of sewage technical route. For a long time, the technical route of centralized sewage treatment has limited the research, innovation and promotion of sewage treatment technology to the sewage treatment process technology for individual projects of sewage treatment plants based on physical, chemical or biological methods. [0003] The existing technology of sewage collection, discharge and sewage treatment ...

AI Technical Summary

Problems solved by technology

[0004] 1. The project land cost is high

[0005] The pipe network system for sewage collection and discharge needs to occupy a large amount of public land, and the sewage treatment plant for centralized sewage treatment also needs to occupy a large area of ​​land, because the land occupied by sewage collection and discharge projects cannot be used for sewage treatment and sewage treatment The land occupied by the project cannot be used for sewage collection and discharge. The existing operation mode of sewage collection, discharge and sewage treatment does not conform to the national land policy direction of saving land and intensive land use

[0006] 2. It is difficult to select a site for a sewage treatment plant

[0007] Residents in sewage collection, discharge and sewage treatment areas have a higher tolerance for sewage collection and discharge projects due to their enhanced awareness of environmental protection and the necessity of sewage collection and discharge, but they often base their efforts on the development of the area based on self-interest. Sewage treatment projects with centralized sewage treatment have a repulsion mentality, which leads to the social reality that it is difficult to select a location for sewage treatment plants

[0008] 3. It is difficult to synchronize the construction of sewage collection, discharge system and sewage treatment system, and cannot form a balanced utilization of resources. There is often an unbalanced phenomenon of serious shortage or serious waste of resources in a certain aspect

[0009] 4. The supervision of sewage collection, discharge system and sewage treatment system is mainly carried out through administrative means, and it is difficult to form a market supervision mechanism among sewage discharge entities, drainage companies and sewage treatment plants

[0010] 5. From a technical point of view, the sewage collection and discharge pipe network system also needs to maintain the long-term stable operation of the pipe network system through environmental protection processes such as grid decontamination, sand removal, and waste gas treatment. Drainage companies are not the main body of environmental protection and lack the ability of environmental protection technology; and the sewage treatment plants that carry out centralized sewage treatment have a large workload on the equipment due to the large amount of sewage treatment. Once a major equipment quality accident occurs or major equipment maintenance is required Or when it is necessary to upgrade the technology of equipment, it often directly affects the quality of sewage treatment

Therefore, the existing operation mode of sewage collection, discharge and sewage treatment cannot effectively solve the stability problem of system operation

[0011] 6. Sewage must flow through long-distance pipeline systems from the collection port to the final discharge port. The existing operation mode of sewage collection, discharge and sewage treatment cannot make scientific use of the residence time and pipeline system of sewage in the collection and discharge pipeline system The space is limited to the sewage treatment process, and the comprehensive utilization of resources cannot be realized

[0012] 7. With the development of the national economy, the discharge of sewage in urban areas continues to increase. The technical route of centralized sewage treatment requires the expansion of the scale of the original sewage treatment plant, and the scale of the new sewage treatment plant is also getting bigger and bigger. The equipment of the sewage treatment plant The large scale is not conducive to the application of modularization, automation and intelligent technology

[0013] 8. The technical route of centralized sewage treatment means that sewage treatment plants can only be located in areas far away from the main water use areas of cities and towns, and supporting facilities need to be built for the reuse of reclaimed water discharged after treatment, and the cost of reclaimed water reuse is high
