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 i

Embodiment 1

[0027] An integrated device for road rainwater purification, which is installed at the collection point of road rainwater, including a primary purification area 1 and a filtration purification area 2, a partition wall is set between the primary purification area 1 and the filtration purification area 2, and the top of the partition wall A diversion port 6 connecting the primary purification zone 1 and the filtration purification zone 2 is set up; an integrated functional filter element 8 is set in the filtration purification zone 2, and the primary purification zone 1 and the filtration purification zone 2 are all filtered The drainage pipe 9 at the bottom of the purification area 2 outputs purified water to the rainwater pipe network. The volume ratio of the primary purification zone 1 and the filtration purification zone 2 is 1:1.

[0028] The upper surface of the primary purification area 1 is provided with a metal fence-type drain 3, and a filter 4 is arranged below the dr...

Embodiment 2

[0032]The way of filtering and purifying the integrated device in Example 1 is as follows: the rainwater collected on the road and carrying a large amount of pollutants enters the primary purification zone 1 from the outlet 3, and the outlet 3 has the shape characteristics and functions of the traditional rainwater grate structure. Large leaves, branches and garbage in the rainwater are intercepted by the drain 3, and the rainwater enters the area below the filter 4 through the side filter 4 through natural gravity, and the leaves, garbage, and large particles entering the device through the drain 3 are again Collected and intercepted, the rainwater passing through the filter screen 4 is subjected to precipitation and buffering in the primary purification area to remove particles such as sediment, and the precipitated rainwater further flows into the filter tank 7 of the filtration purification area 2 through the diversion port 6, And through the functional filter element 8 for...

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...
