Embodiment Construction

[0034] The method for the water quality-based discharge of the urban river rain-sewage mixed-flow pipe network of the present invention is to install a water-flow-based discharge system at the outlet of the urban river rain-sewage mixed-flow pipe network (hereinafter referred to as the drainage pipe), so as to realize the water flow quality-based discharge. In the following, the present invention will be further described in conjunction with the drawings and structure of a water flow classification and discharge system in a specific embodiment.

[0035] Provide a diverter pipe at the exit section of the existing drain. As shown in longitudinal section figure 1 shown. exist figure 1 Among them, the connecting pipe A of the distribution pipe, the sewage pipe B, and the rainwater discharge pipe C are connected, and the D part is an independent digital data processor, which can also be controlled by a remote digital data processing center.

[0036] The three inner diameters of ...

Abstract

The invention relates to a method for discharging water separated, used in mixed tube of city. Wherein, it comprises: arrange diversion tube at the outlet of former discharge tube; the section of diversion tube near the discharge tube has detecting area; the detecting area is arranged with water quality detecting sensor which will transmit the detected water quality to the digit data processor; the processor will process the data to form river water quality factor, to be compared with diversion critical value, to control and select the diversion device to confirm that the water is discharged from the rain discharge tube or sewage tube. The invention can automatically divert water via water quality, to make rain into rain discharge tube and sewage into sewage tube.

Description

technical field [0001] The invention relates to a method for controlling water flow pollution in mixed flow rivers of urban rainwater and sewage, in particular to a method for performing quality-specific discharge of water bodies in urban river rainwater and sewage mixed flow pipe networks. Background technique [0002] At present, the known urban river pollution control mainly includes physical, chemical, biological and other methods and measures: such as cutting off pollution sources from point sources and non-point sources, biodegrading polluted river water, chemical degradation to improve water quality, and sending sewage into sewage Treatment plants, etc., to ensure that the water quality of rivers meets the requirements of different management objectives. [0003] Among them, in order to prevent the water quality of the river from being polluted, the most important and basic measure is to cut off the source of pollution entering the river. [0004] Because people's co...
