Embodiment

[0037] In this embodiment, when implementing a specific project, Q can also obtain a certain fixed value according to other calculation methods such as a local rainstorm intensity calculation formula.

[0038] The first water volume setting threshold is 10% of the rainwater interception flow Q in the catchment area, i.e. 10% Q; the second water volume setting threshold is the 3-day maximum design water volume of the vertical flow wetland 33 and 3 of the aeration vertical flow wetland 34 The sum of the maximum design water volume per day is 130%Q; the maximum design water volume of the vertical flow wetland 33 for 3 days is 130% of the average design water volume of the vertical flow wetland 33 for 3 days, and the maximum design water volume of the aeration vertical flow wetland 34 for 3 days is The average design water volume of aeration vertical flow wetland 34 is 130% of the 3-day accumulation; the COD threshold of the influent is 50mg / L; the COD threshold of the drainage is ...

Abstract

The invention relates to an intelligent system and method for regulation and control of urban runoff rainwater via wetland. Inflow water involved in the invention is direct surface runoff in a catchment area around a riverway and mixed-flow sewage possibly occurring in non-rainfall weather. The intelligent regulation and control system comprises aclosure intercepting unit, a wetland unit, an inflow inlet judgment unit, an outflow water judgment unit and a regulation unit, wherein the intercepting unit is used for intercepting inflow water; the wetland unit is used for carrying out advanced treatment on the inflow water; the inflow water judgment unit and the outflow water judgment unit are used for providing judgment basis for water inflow and water outflow of the wetland unit; and the regulation unit is used for regulating and controlling the wetland unit under the conditions of different inflow water qualities and inflow water quantities and different outflow water qualities and outflow water quantities. According to the intelligent regulation and control system for treating direct surface runoff and mixed-flow sewage possibly occurring in non-rainfall weather provided by the invention, different inflow and outflow water qualities and different inflow and outflow water quantities can be intelligently regulated, and the method enables the system to have higher use efficiency and is suitable for places surrounding riverways in urban and rural areas and in urban-rural junctions.

Description

technical field [0001] The invention relates to the technical field of artificial wetlands, in particular to an intelligent control system and method for urban runoff rainwater wetlands. Background technique [0002] With the rapid development of urbanization, the proportion of impermeable areas in cities is getting heavier and heavier, resulting in heavy rainfall in rainy days, especially heavy rains. A large amount of runoff enters municipal sewage plants and urban rivers through pipes, resulting in high pressure for rainwater storage. , if not treated in time, it is easy to cause waterlogging. [0003] During the rainfall process, rainwater also carries a large number of pollutants, such as a large amount of acid gas in the dissolved air, vehicle exhaust, factory exhaust gas and other polluting gases, pollutants caused by washing roofs, asphalt concrete roads, etc.; its pollutants even It exceeds the pollution level of ordinary urban sewage. If it is not treated, it wil...
