The invention provides a surface source ecological purification system which comprises a drainage channel, multiple protruding stones are embedded in the base plate of the drainage channel along water flow path to form a blocking unit, downstream of the drainage channel is connected with a water-collecting well to form a depositing unit, one side of the water-collecting well is provided with a water distribution weir and a water distribution pool to form a water distribution unit, the height of the water distribution weir is less than that of the base plate of the drainage channel, the height of the bottom of the water distribution pool is less than that of the water distribution weir, the water distribution pool is communicated with multiple water distribution pipes, water distribution holes are formed in the water distribution pipes, a gravel processing unit is arranged under the water distribution unit, gravel with different grain diameters are filled in the gravel processing unit, a supporting plate is arranged at the bottom of the gravel processing unit, drainage holes are formed in the supporting plate, and a discharge channel is arranged under the supporting plate. According to the surface source ecological purification system, modular operation can be achieved, and the system has the advantages of being short in shaping time and good in purifying effect, and the system can be used for processing initial rainwater surface source runoff with high flow velocity and high particle concentration so that contamination caused by rainwater runoff to receiving water can be reduced.
Description
Technical field [0001] The invention belongs to the technical field of ecological environment engineering, and particularly relates to a non-point source ecological purification system. Background technique [0002] At present, with the increase in the control of point pollution sources, the contribution rate of point sources to water pollution is decreasing year by year, while the proportion of non-point source pollution load is increasing year by year. Non-point source pollution can be divided into agricultural non-point source, urban non-point source, mine non-point source, atmospheric deposition, etc. according to the different regions. [0003] Urban non-point source pollution is also called urban storm runoff pollution, which means that under the conditions of precipitation, rainwater and runoff wash the urban ground, and the polluted runoff is transmitted through the drainage system, which pollutes the water quality of the receiving water body. Non-point source pollutants c...
