Background technology
Water is Source of life.The world today faces serious water crisis.Shortage of water resources has become the significant problem that is related to poverty, Sustainable development and even international peace and security.United Nations emphasized again and again over the past two years that the big city water resources was the emphasis in world's water resources problems, and management is city water resource the very corn of a subject.Become the trend of international water management based on the city water resource integrated management in basin.
Water environmental problems is of long duration in China, and especially in recent years, under the dual-pressure of shortage of water resources and water pollution, water environmental problems was on the rise, and shortage of water resources has become one of principal element of development of restriction Chinese society and economic construction.In more than 600 organizational system city of China, more than 400 urban water shortage arranged, wherein more than 100 is serious water shortage.Because a large amount of raw sewerages directly enter rivers,lakes and seas, the whole nation has 50% section to be polluted, water pollution is serious near the 90% above city, 50% above water body in lake eutrophication, water pollute extend from the Zhi Liuxiang master stream, from the city to the rural area spread, from regionality to basin-wide development, from the face of land to underground deep, the water surrounding present situation is troubling.Formulation meets the Sustainable Water Resources Development strategy of social economic environment target, strengthens water resources protection, administers that water pollutes, the protection water surrounding, safeguards ecosystem balance on the basis of human's demand satisfying, and becomes problem demanding prompt solution.
As the important component part of water resources management, water pollution control plays an important role in quality of water environment improves.The entire sewage treatment system is carried out integrated planning and control as a Controlling System, promptly according to the water quality of river requirement, combined sewage water overflow and municipal sewage plant's operation conditions of control urban drainage pipe network can realize the improvement of water ecological environment when reducing run cost.The urban sewage treatment system integration Management is the development trend of municipal sewage treatment and the effective way that realizes urban sustainable development, also is construction information city, indispensable important component part of structure urban information resource system.
The actual sewage treatment system belongs to huge distributed system, and is under the jurisdiction of different division managements such as municipal administration, environmental protection, water conservancy respectively, is difficult to directly carry out the research and experiment checking of Collaborative Control scheme.In order to carry out the Collaborative Control research between pipe network, sewage work and the river, must foundation can effectively simulate the experimental system of integrated system.
Summary of the invention
The object of the present invention is to provide a kind of integrated network, sewage work and river set up in the water treatment of one and the method for control experimental installation, realize of the simulation of three sub-system relationship relations with the integrated system service performance.On the basis of fully research pipe network water force characteristic and biochemical reaction characteristic, sewage work's biochemical reaction mechanism and operation characteristic and river hydraulic performance and biochemical reaction characteristic, by computer simulation the incidence relation of pipe network, sewage work, three subsystems in river.On this basis, set up the water treatment and control experimental system of integrated network, sewage work and river in one.
The objective of the invention is to be achieved through the following technical solutions:
Integrated network, Sewage Plant and river are in the water treatment and control experimental system of one, pipe network, sewage work and river are integrated in one, realize Collaborative Control, the river adopts cascade aeration tank and two kinds of simulator of open type pipe die respectively, sewage work adopts A2/O, SBR, three kinds of different technologies of anaerobic digester respectively, pipe network adopts cascade reaction pond and two kinds of simulator of enclosed pipe die respectively, and three subsystems are set up association, and the water outlet of pipe network is by water pump input Sewage Plant or river; The water outlet of sewage work is delivered to the river by water pump, and online multi-parameter water quality tester is set, and test signal links to each other with the PLC system, and main water quality parameter is monitored in real time.
Aforesaid integrated network, Sewage Plant and river are in the water treatment and control experimental system of one, isolated operation can be distinguished by pipe network, river, sewage work, but also overall operation, pipe network, river, sewage work all realize monitoring in real time by the PLC Controlling System.
Advantage of the present invention and effect are:
But pipe die formula sewage network collection is failed analogue experiment installation, anaerobism cascade reactor and the both parallel runnings of anoxic cascade reactor, but also series operation is convenient to realize the Optimization Dispatching research of pipe network.Adopt the parallel running mode, but every kind of technology mode isolated operation can move simultaneously also.
Description of drawings
Accompanying drawing of the present invention is the water treatment and control experimental system synoptic diagram in one of integrated network, Sewage Plant and river.
Embodiment
The present invention is described in detail with reference to the accompanying drawings.
Among the figure: 1. pipe die formula sewage network simulator 2. is based on the sewage network experimental installation 3.A of CSTR
2/ O sewage treatment process simulator 4.SBR sewage treatment process simulator 5. anaerobic digestion sewage treatment process simulator 6. pipe die formula water quality of river simulator 7. are based on the water quality of river simulator of CSTR
The present invention sets up the mathematical model in pipe network, sewage work and river respectively, by numerical simulation determine three subsystems separately service performance and the mutual relationship between the three.Use for reference the Study on Numerical Simulation result, design the simulator of three subsystems of realistic system characteristic, then according to incidence relation between the three and coordinated operation needs, the analogue experiment installation of three subsystems is integrated and connected, finish whole experimental system and build.According to the controlling unit of three subsystems of part control requirement design, according to global collaborative control requirement, what design whole experimental system is pipe network, Sewage Plant, the river cooperative control system of target with the water quality of river then.
