Problems solved by technology

Mechanical abandonment mostly uses levers, pulleys, float valves and other partial control valves to close, which is insufficient in control accuracy
And it is impossible to comprehensively judge the timing of valve opening and closing based on rainfall and rainfall duration, and it is impossible to effectively define the initial rainwater for different underlying surfaces and functional areas
On the one hand, if the flow value defined by the initial rainwater is greater than the actual flow value, it may cause insufficient utilization of the treatment equipment for initial rainwater control; on the other hand, if the flow value defined by the initial rainwater is smaller than the actual flow value, it may cause The abandonment of the initial rainwater is not complete, so that part of the initial rainwater directly enters the river, causing pollution to the water body
The traditional initial rainwater abandonment device has relatively simple definition conditions for initial rainwater, which often causes pollution of rainwater pipes or reused water pipes, or their insufficient utilization; it also causes the amount of rainwater flowing into municipal sewage pipes and sewage treatment plants to exceed the design flow rate

Embodiment 1

[0049] A rainwater outlet for intelligent collection and diversion of initial rainwater is applied in East China, taking the carriageway in the old city of Suzhou as an example. The average annual precipitation in Suzhou City is about 1093 mm, and the precipitation from April to September accounts for about 70% of the annual precipitation. Road runoff pollutants are mainly SS and COD. According to the May rainfall change curve and runoff pollutant change curve of Suzhou old city roads, the threshold of rain gauge 14 is set to 7mm, the threshold of timer 15 in sensor 5 is 30min, and the rainwater pipe 11 is connected to the rainwater drainage pipe.

[0050] In the early stage of rainfall, the side baffle 3 is closed, the valve 8 on the connecting pipe 7 is closed, the valve 9 on the sewage pipe 10 is opened, and the polluted initial rainwater is collected and discharged into the municipal sewage pipe 10 through the flat grate rainwater outlet 2. The municipal sewage is sent to ...

Embodiment 2

[0055] A rainwater outlet for intelligent collection and diversion of initial rainwater is applied in Northwest China, taking the carriageway of Fengxi New Town, Xixian New District, Xi'an City as an example. The average annual precipitation in Xi'an is about 520 mm, and the precipitation from July to September accounts for about 50% of the annual precipitation. The runoff pollutants in the square are mainly SS and COD. According to the change curve of rainfall and runoff pollutants in Fengxi New Town Square, the threshold value of the discharge flow of the rain gauge 14 is 8mm, the threshold value of the timer 15 in the sensor 5 is 35min, and the rainwater pipe 11 is connected to the reuse water pipe.

[0056] When the ground runoff is small in the initial stage of rainfall, the side baffle 3 is closed, the valve 8 on the connecting pipe 7 is closed, the valve 9 on the sewage pipe 10 is opened, and the initial rainwater with high pollution is collected and discharged into the ...

Abstract

The invention relates to an initial rainwater intelligent collecting and diverting gutter inlet and a diverting method, and belongs to the technical field of initial rainwater control. According to the initial rainwater intelligent collecting and diverting gutter inlet, a flat grate gutter inlet located in a road plane is formed in a rainwater vertical shaft, the flat grate gutter inlet is locatedin one side of curbstone, and the rainwater vertical shaft is communicated with a municipal sewage pipe. An independent first rainwater vertical shaft is further arranged at one side of the rainwatervertical shaft; a lateral gutter inlet is formed in the side, facing the flat grate gutter inlet, of the curbstone; a baffle capable of being opened and closed is arranged on the lateral gutter inlet; the lateral gutter inlet is communicated with the independent first rainwater vertical shaft below the lateral gutter inlet; the rainwater vertical shaft is communicated with the first rainwater vertical shaft through a connecting pipe; and a rainwater pipe or a recycled water pipe is also arranged on the first rainwater vertical shaft. The initial rainwater intelligent collecting and divertinggutter inlet and the diverting method can be applied to different areas and different functional areas, and the initial rainwater defining ground runoff volume and rainfall duration of the areas can be independently and flexibly set according to different initial rainwater defining standards, so that refined diverting of each module is achieved.

Description

technical field [0001] The invention relates to an intelligent collection and diversion rainwater opening and a diversion method of initial rainwater, and belongs to the technical field of initial rainwater control. Background technique [0002] Initial rainwater generally refers to the rainwater during the first 15 minutes, 20 minutes or 30 minutes of rainfall, or the rainwater runoff of the first 7 mm of rainfall. The initial rainwater generally contains pollutants such as organic matter, SS, TP, and heavy metals, and the pollution load is high and difficult to control. If the initial rainwater is directly discharged into the natural water body through the rainwater pipe, it will cause very serious pollution to the natural water body, and it will also affect the reuse of subsequent rainwater. At present, the main treatment methods for the source of initial rainwater are interception of sewage at the storm water outlet and abandonment of initial rainwater. [0003] The ...
