Description
Technical Field
The invention relates to a riverway pollution bypass purification system strengthened by electrolysis, and belongs to the technical field of riverway purification and sewage treatment.
Background
The healthy urban water environment is an important guarantee for urban sustainable development. However, with the rapid development of economy and the acceleration of urbanization, the problems of water quality pollution and ecological degradation of many urban rivers in China are prominent, and even the phenomenon of black and odorous water bodies in seasonal and perennial water bodies occurs. According to the requirements of 'action plan for preventing and treating water pollution', the proportion of excellent water quality (reaching or being superior to III) of seven key drainage basins such as Yangtze river, yellow river, Zhujiang river, Songhua river, Huaihe river, Haihe river, Liaohe river and the like is up to more than 70% in general by 2020, and black and odorous water bodies in built-up areas of land level and above cities are controlled within 10%. By 2030, the excellent proportion of water quality of seven major key drainage basins in China is over 75 percent, black and odorous water in urban built-up areas is eliminated totally, and the water quality of urban centralized drinking water sources is about 95 percent or more than that of the III analogy examples totally. Therefore, solving the problems of urban river pollution and restoring the ecological and social functions of rivers is one of the key tasks to be solved urgently in the process of urban sustainable development.
However, under the current situation, although the point source pollution is well controlled, with the accelerated urbanization and the increase of the urban impervious surface area, the discharge amount of the domestic pollution is increased, and the problems of mixed connection and misconnection of the rainwater pipe and the sewage pipe cannot be completely solved, so that a part of rainwater and sewage mixed flow phenomenon still exists in the current river inlet discharge port, and the river water quality is seriously influenced. Meanwhile, a large amount of non-point source pollution also carries a large amount of suspended particulate matters, nitrogen, phosphorus and COD into the river, which seriously affect the water quality of the river and even cause black and odorous phenomena. A large amount of suspended particles enter a river to increase water particles and influence the growth of aquatic plants, so that the water loses the self-cleaning capability.
Aiming at the problems at present, efficient purification measures are needed to rapidly reduce river pollution so as to improve the transparency of the water body, reduce the contents of nitrogen, phosphorus and COD, improve the habitat of aquatic plants, improve the self-purification capacity of the water body and recover an aquatic ecosystem.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a riverway pollution bypass purification system strengthened by electrolysis, namely a system capable of efficiently intercepting and purifying mixed flow sewage and rainwater containing pollutants and suspended particulate matters with high concentration in a river inlet discharge port.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a riverway pollution bypass purification system strengthened by electrolysis comprises a collecting and lifting structure for collecting sewage at a drainage port in a riverway, an aerobic-anoxic combined artificial wetland structure connected with the collecting and lifting structure, and a drainage structure connected with the aerobic-anoxic combined artificial wetland structure, wherein the aerobic-anoxic combined artificial wetland structure comprises an aerobic electrolysis strengthening artificial wetland structure and an anoxic electrolysis strengthening artificial wetland structure, the collecting and lifting structure, the aerobic electrolysis strengthening artificial wetland structure, the anoxic electrolysis strengthening artificial wetland structure and the drainage structure are sequentially connected, the collecting and lifting structure discharges the sewage to be treated in the riverway into the aerobic electrolysis strengthening artificial wetland structure for treatment, then the sewage flows through the anoxic electrolysis strengthening artificial wetland structure for treatment, and finally the sewage is discharged into the riverway through the drainage structure.
Furthermore, the aerobic electrolysis strengthening constructed wetland structure is an oxidation pond type constructed wetland and comprises a first water inlet connected with the collecting and lifting structure, a pond body structure connected with the first water inlet and a first water outlet connected with the pond body structure, wherein a first electrolysis strengthening system, pond body aquatic weeds and underwater nano aeration equipment are arranged in the pond body structure.
Furthermore, the first electrolytic strengthening system comprises a first stabilized voltage power supply arranged outside the pond body structure and a first electrode system arranged according to the size of the pond body structure; the first electrode system takes the graphite felt as a cathode and an anode, and uses civil electricity to continuously supply power through a first voltage-stabilizing power supply.
Furthermore, the first water inlet and the first water outlet are both arranged at the upper part of the pond body structure, and the first water inlet and the first water outlet are oppositely arranged on the pond body structure.
Furthermore, the anoxic electrolysis strengthening artificial wetland structure is a descending vertical flow deep bed wetland and comprises a second water inlet connected with the aerobic electrolysis strengthening artificial wetland structure, a filter material unit connected with the second water inlet and a second water outlet connected with the prediction unit, wherein a second electrolysis strengthening system is arranged in the filter material unit, and emergent aquatic plants are planted on the upper part of the filter material unit.
Furthermore, the second electrolysis strengthening system comprises a second stabilized voltage power supply arranged outside the filter material unit and a second electrode system arranged inside the filter material unit; the second electrode system takes iron and carbon fibers as anodes and carbon fiber electrodes as cathodes, and civil electricity is adopted to continuously supply power through a second voltage-stabilizing power supply.
Furthermore, the filter material unit comprises a biomass charcoal layer, a ceramsite layer, a volcanic stone layer and a zeolite layer which are sequentially arranged from top to bottom.
Furthermore, the second water inlet is arranged at the upper part of the filtering material unit and receives the effluent from the aerobic electrolysis enhanced artificial wetland structure as inlet water, the second water outlet is arranged at the lower part of the filtering material unit, and the second water inlet and the second water outlet are oppositely arranged on the pond body structure.
Furthermore, the collecting and lifting structure comprises a water pump and a pipeline, the water pump is connected with a river channel and an aerobic-anoxic combined artificial wetland structure, and the mixed flow sewage or initial rainwater entering the river discharge opening is collected and then subjected to purification treatment on suspended particles, COD (chemical oxygen demand) and nitrogen and phosphorus through the artificial wetland structure.
Furthermore, the drainage structure comprises a water pump and a pipeline, the water pump is connected with the aerobic-anoxic combined artificial wetland structure and the river channel, and the water after the purification treatment of suspended particles, COD (chemical oxygen demand) and nitrogen and phosphorus through the artificial wetland structure is discharged into the river channel. In the specific use process, a drainage cut-off structure, a water pump and a pipeline/pipeline of a drainage port can be arranged in the river channel, and drainage port flowing water is introduced into a river channel pollution bypass purification system strengthened by electrolysis for purification treatment and then is drained into the river channel through the drainage structure.
