Integrated device for road rainwater purification

Abstract

The invention discloses an integrated device for road rainwater purification. The device is arranged at a road rainwater collection part and comprises a primary purification area and a filtering purification area, wherein a partition wall is arranged between the primary purification area and the filtering purification area, a flow guide port communicated with the primary purification area and thefiltering purification area is formed above the partition wall, an integrated functional filter core is arranged in the filtering purification area, and the primary purification area and the filteringpurification area output purified water to a rainwater pipe network through a drainage pipe at the bottom of the filtering purification area. The integrated device provided by the invention not onlycan ensure the drainage safety requirement, but also can realize the efficient purification effect on the main indexes TSS, TN, TP and COD of rainwater pollutants, and has efficient antibacterial andbactericidal functions.

Description

technical field [0001] The invention relates to the field of water environment, and relates to an integrated device installed at the front end of a rainwater pipe network for road rainwater confluence purification and reduction of initial rainwater pollution; specifically, it is an integrated device for road rainwater purification. Background technique [0002] In view of the design status of stormwater pipe networks in most cities, a large amount of rainwater runoff from the road surface washes away a large number of tree branches and leaves, sediment, solid suspended particles, and other pollutants such as nitrogen, phosphorus compounds, petroleum hydrocarbons, heavy metals, and pathogenic pathogens. It is directly discharged into the municipal rainwater pipe network without treatment. The first is to cause sediment accumulation and black odor in the rainwater drainage pipe network system. If it is not cleaned up in time, it will cause poor drainage of the pipe network and...

AI Technical Summary

Problems solved by technology

However, these methods only intercept some of the larger particles of pollutants entrained by rainwater to a certain extent, and cannot achieve the detection of suspended or colloidal pollutants and ionic pollutants (which have a key impact on the water quality of terminal water bodies) and pathogens. Effective removal, needs further improvement

In addition, in the current mainstream renovation methods for stormwater outlets, the main monitoring indicators of stormwater pollutants are suspended solids (TSS), nitrogenous pollutants (TN), phosphorus pollutants (TP), COD and large intestine. Little attention has been paid to the comprehensive purification ability of bacilli. The input of these pollutants has caused serious pollution to the water quality of the terminal water body, increased environmental pollution, and greatly increased the workload and economic cost of post-water treatment.
