At present, the draining system in city mainly contains two kinds of forms, i.e. the dirty segregation system of confluence of rainwater and sewage system and rain.China's newly built city district adopts the dirty segregation system of rain, but many old towns remain confluence of rainwater and sewage drainage system processed.Confluence of rainwater and sewage drainage system processed, between storm period, have partially mixed sewage and enter water body by overflow well, forms pollution load of overflow.Quickening along with urbanization process, the pollution load of overflow problem of Combined Municipal drainage pipe becomes day by day serious, part rain, the unprocessed overflow of dirty mixing water enter river, cause the water body severe contamination, have become urban and have improved one of main restricting factor of water quality.
Combined drainage system mainly transmits sanitary sewage in dry season, in rainy season, pollutant in atmosphere, ground and soil also enters combined drainage system under the leaching of rainfall runoff and souring, be mixed to form rain sewage interflow with sanitary sewage and be transferred to Wastewater Treatment Plant.When flow has surpassed the receptive capacity of combined drainage system, part rain sewage overflows to water body by overflow well, forms pollution load of overflow.Show by a large amount of investigation both at home and abroad, rainfall initial stage storm runoff has often carried a large amount of pollutants, and the high water yield of its pollution intensity is large, and rainfall middle and later periods runoff pollution intensity significantly alleviates.The rainfall Initial Runoff pollutes and accounts for whole flush period pollution load major part, and this part pollution need to be transported to Wastewater Treatment Plant by the pipe network that dams and process, and qualified discharge alleviates the runoff pollution load.
The city old city changes combined system into segregation system at present, is subjected to the tale quale restriction large, and it is longer that the age is built up in many old towns, the underground utilities basic forming, and surface structures is crowded, road narrows, it is larger that old combined system changes the segregation system difficulty.Therefore, to existing combined sewer overflow dam, the aggregate measures such as processing to be to control its pollution, take measures simultaneously to control Water in Rainwater Drainage high-volume and rate of discharge, and control the discharging of pollutant in the runoff rainwater.
Summary of the invention
Combined drainage system is to collect by a set of tubes drainage system of carrying sanitary sewage and rainwater.Generally, the pipe network capacity of combined drainage system and Wastewater Treatment Plant's finite capacity, the rain sewage that heavy rain dams season can surpass its capacity, this need to be detained the sanitary sewage of certain hour section, reserve the volume transport rainwater, after rainfall stops, then the sanitary sewage that will be detained imports normal transmission in the combined system pipe network.In order to reach this purpose, the invention combined sewage pipe network time-staggered flow distribution control system, apply it to existing combined system pipe network system, realizes the shunting of staggering the time of rain sewage.
Combined sewer system is comprised of septic tank, inlet for stom water, combined system pipe network arm, catchpit, dam main and Wastewater Treatment Plant.The present invention is combined sewage pipe network time-staggered flow distribution control system, and it is installed in existing Combined sewer system, realizes between storm period the shunting of staggering the time of sewage and rainwater.Combined sewage pipe network time-staggered flow distribution control system of the present invention, be comprised of motor operated valve, electric brake, electronic weir, central controller four parts.Motor operated valve is installed on septic tank outlet pipe end, realizes that in septic tank, sewage goes out whether to flow; Electric brake and electronic weir are placed in catchpit, and wherein electric brake is installed in catchpit the main that the dams end that becomes a mandarin, and electronic weir is installed on the return side of catchpit, and both link and control the flow direction of rainwater or sewage.Central controller save command program, control switch and the time delay on motor operated valve, electric brake and electronic weir by wireless mode.Heavy rain at first, central controller is by the wireless way for transmitting instruction, realize closing of motor operated valve, septic tank outlet sewage is stranded in septic tank, the Preliminary sewage that transports in combined system pipe network arm reduces, and reserves the rainwater that the capacity of transporting is admitted to inlet for stom water, and between storm period, combined system pipe network arm transports rainwater, import by catchpit the main that dams, send into Wastewater Treatment Plant and process; After the heavy rain certain hour, by central controller, by the wireless way for transmitting instruction, realize the reduction with position, weir, electronic weir of closing of electric brake, the rainwater that this moment, combined system pipe network arm transported is crossed electronic weir and is entered in river; After heavy rain stops, pass through the wireless way for transmitting instruction by central controller, realize the unlatching of motor operated valve, the unlatching of electric brake and the lifting of position, weir, electronic weir, the sewage that is detained between the septic tank storm period this moment goes out stream, transport by combined system pipe network arm, import by the unlatching of the electric brake in catchpit the main that dams and send into Wastewater Treatment Plant.
