Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing:

[0032] Such as Figure 1-6As shown, a runoff rainwater interception device based on light-sensing technology includes an outer well 1, an inner well 2, an inlet pipe 3, an outlet pipe 4, an intercepting pipe 5, an electric flap 6, a water pump 8, and a photodetector 9. Controller 10, power line 11, signal line 12, flow rate sensor 18, diversion groove 19, connecting pipe 28. The outer well 1 is placed below the ground 13 and is composed of a well bottom 15, an outer well wall 16 and a cover plate 14, and has a rectangular cross section. The well bottom 15 adopts concrete pouring to form a horizontal plane, and the outer well wall 16 adopts mortar and bricks to form an upright wall. The cover plate 14 is a rectangular plate made of concrete, metal, plastic and other materials. Inner well 2 cross-section is rectangular, is close to outer well 1 corner and arranges, and out...

Abstract

The invention discloses a runoff rainwater quality dividing intercepting device and method based on the light sensation technology, and belongs to the technical field of drainage pipelines. The device is composed of an inner well and an outer well. An electric turnover plate which can rotate around a rotating shaft is installed in the inner well, a water inlet pipe, a water outlet pipe and an intercepting pipe are installed on the well wall, and a water pump, a light sensation detector, a flow sensor and a controller are installed in the interlayer space of the inner and outer wells. When the flow sensor detects that water exists in the water inlet pipe, a system is started automatically. The water pump feeds rainwater into the light sensation detector, and the transmission light intensity of the rainwater is measured and converted into electric signals; the cleaner the rainwater is, the higher the transmission light intensity is, and the larger the electric signal intensity is. When the electric signals are weak, the automatic control system indicates the electric turnover plate to rotate to be in the vertical state, and the rainwater is intercepted to the intercepting pipe and fed into a sewage pipe or a sewage pond; otherwise, the electric turnover plate is rotated to be in the horizontal state, the rainwater enters the water outlet pipe to be drained into a riverway. The device is linked with the water quality, accurate intercepting of high-concentration runoff rainwater is achieved, and the device is high in sensitivity, short in response time and convenient to operate and manage.

Description

technical field [0001] The invention belongs to the technical field of drainage pipes, and relates to a runoff rainwater interception device and method, in particular to an interception device and method for intercepting high-concentration polluted runoff rainwater and discharging low-concentration clean runoff rainwater by using photoelectric induction technology. Background technique [0002] Rainfall washes away atmospheric dust and ground pollutants, forming surface runoff rainwater, which is directly discharged into urban rivers and lakes through municipal drainage pipe networks, causing serious pollution to the water environment. According to the survey, the average concentration of SS (suspended solids), COD, ammonia nitrogen, total phosphorus and total nitrogen in runoff rainwater is relatively high, among which the concentration of SS is higher than that of urban sewage, and the concentration of other pollutants exceeds the limit of the first-class B standard for sew...
