Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
The present invention is a kind of parallel works utilizing concentration control and water lev el control pattern to carry out sub-prime component water conservancy diversion.
The concentration that the present invention proposes controls, and refers to and carries out water conservancy diversion when carrying out rainwater diversion according to the concentration of outfall and discharge pipe line internal contamination thing, and water conservancy diversion is regulated and stored high concentration rainwater selectively, realizes the maximization of rainwater pollution control effects.Because the pollutant levels of discharging rainwater under different rain types reach peak concentration required time difference, therefore, the water conservancy diversion time should be corresponding with the pollutant levels peak fractions time, instead of dam in a few minutes at rainfall initial stage simply or the rainfall runoff of several millimeters.According to emission request, arrange different concentration control laws, when after rainfall, rainwater pollution substrate concentration does not reach controlled concentration, rainwater directly enters rainfall pumping station or row river; When concentration of emission is greater than controlled concentration, guiding device starts rainwater in drain measure mouth and discharge pipe line, till storing completely.
The water lev el control that the present invention proposes, refers to and is utilizing the ability of Storm Sewer Network water capacity to regulate and store at ordinary times, leaks, form certain water level, select opportunity and the water conservancy diversion time of water conservancy diversion according to the change of water level in its pipe network owing to there is the dirty hybrid junction of dry flow sewage and rain.
See Fig. 1, Fig. 2 and Fig. 3, water conservancy diversion pond 1 of the present invention is the rectangle structure closed, and the pond body length in the water conservancy diversion pond 1 of specific embodiment is 6m, and high 3m, wide 3m are concrete structure.Both ends of the surface along water conservancy diversion pond 1 longitudinal direction are respectively arranged with inlet opening 2 and weep hole 3, inlet opening 2 is provided with U-type groove 10 with the below of connection, water conservancy diversion pond 1, be provided with pollutant monitoring probe 6 in U-type groove 10, pollutant monitoring probe 6 is arranged on the sidewall of pond body and is connected with control panel 9 by water quality signal input line 7; Diversion U-type groove has the gradient of 10 degree, no matter can ensure that the water inlet of much water yields all can pop one's head in 6 through pollutant monitoring the very first time.Before pollutant monitoring probe 6, the antetheca of side, inlet opening is provided with baffle plate 11, for blocking directly the washing away detection probe when Rainfall runoff is excessive, to extend the application life of detection probe.
On the longitudinal center position in water conservancy diversion pond 1, pollutant monitoring pop one's head in 6 same sidewalls, be provided with content gauge 13, content gauge 13 is connected with control panel 9 by liquid level signal input line 14; The weep hole side in water conservancy diversion pond 1, the bottom of the same sidewall of content gauge 13 is provided with pod apertures 14, pod apertures 14 is connected with self priming pump 6 and reversing valve 15 in turn, and self priming pump 5 is connected with control panel 9 by wire; Manhole 12 is also provided with above water conservancy diversion pond 1.
Described control panel 9 can be arranged in the Control Room of rainfall pumping station, and is provided with automatic checkout system.
Operating principle of the present invention is as follows:
When pollutant monitoring probe 6 detects that water concentration reaches the controlled concentration of setting, automatically controlled control panel 9 sends instruction, convey to self priming pump 5 by output line 8, self priming pump 5 is started working, and high pollution rainwater in the body of pond is passed through pod apertures 4 water conservancy diversion in the subsequent treatment structure in downstream.When pollutant monitoring probe 6 detects water concentration lower than the controlled concentration set, electric-control board 9 can send instruction, and self priming pump 5 quits work, and clean rainwater enters Forebay of Pumping Station by weep hole 3.
When adopting the water yield water conservancy diversion pattern dry season, control signal adopts the measured value of content gauge 13.Owing to there is the situation of the dirty hybrid junction of rain, so have certain water-holding quantity in rain drainage pipe, level value raises gradually with the accumulation of rate of water added, water level in content gauge 13 Real-Time Monitoring pipeline, water level in the real-time display pipes of electric-control board 9, when reaching the setting value needing draining, electric-control board 9 sends instruction, and self priming pump 5 is started working, when water level falls after rise to comparatively low water stage, electric-control board 9 sends instruction again, and self priming pump 5 quits work.
In addition, below reversing valve 15 is also provided with at self priming pump 5, to prevent aqueous reflux in diversion pipeline in water conservancy diversion pond.
During without rainfall, import in the body of clean water confrontation pond by manhole 12 and rinse, avoid the deposition of pollutant.
Whole water conservancy diversion pond of the present invention body is arranged on the front end of region Storm Sewer Network end, rainfall pumping station forebay.
