Urban runoff is surface runoff of precipitation created by urbanization. This runoff is a major source of flooding and water pollution in urban communities worldwide. Impervious surfaces, such as roads, parking lots, rooftops and sidewalks, are constructed during land development. During rain storms and other precipitation events, these surfaces carry polluted stormwater to storm drains, instead of allowing the water to percolate through soil. Most municipal storm sewer systems discharge stormwater without treatment to streams, rivers and other water bodies. Urban runoff carries a mixture of such pollutants as sediment, fertilizers, bacteria, metals and more.
A construction design method for a biological retention facility based on RF-GA fitting and electronic equipment
ActiveCN120873734BImprove purification effectMake up for experience-based designEnvironmental resource managementOriginal data
The application discloses a kind of based on RF-GA fitting biological retention facility construction design method and electronic equipment, comprising: with existing biological retention facility hierarchical structure parameter and existing environmental parameter establish original data set;Existing environmental parameter includes when running city runoff rainwater concentration and the concentration data of effluent after treating pollutant;Original data set is used for training RF model after being preprocessed;Acquire target city environmental parameter, determine the numerical range of different structure parameters in existing biological retention facility hierarchical structure parameter, and splice with target city environmental parameter;Spliced data is input into the RF model trained, combined with GA algorithm, obtain the parameter combination of target city biological retention facility hierarchical structure and the effluent concentration of pollutant under this combination;Based on this method, the hierarchical structure of biological retention facility can be designed specifically, and the effluent quality of this hierarchical structure is predicted, which helps to improve the purification effect of biological retention facility.
