Embodiment 1

[0053] An emergency system for highway bridge deck runoff purification, which is divided into three areas: a pre-settling area 1, an oil removal area 2, and a deep purification area 3 through a partition wall 11, a first oil removal partition wall 13, and a second oil removal partition wall 20 The water inlet pipe 4 arranged on the top of the road bridge deck runoff purification emergency system can collect the bridge deck runoff and lead to the pre-settling area 1; the supporting bottom wall 15 vertically standing at the bottom of the pre-settling area 1 pool is further The runoff rises and is introduced into the degreasing zone 2, which is composed of the space between the first degreasing partition wall 13 and the second degreasing partition wall 20 constructed on both sides of the supporting bottom wall 15, so The bottom of the degreasing partition wall 13 maintains a certain height with the bottom of the pre-settling area 1 pool, on which a floating degreaser 6 is suspende...

experiment example 1

[0057] The emergency system for highway bridge deck runoff purification is as in Example 1. Specifically, the bottom of the floating degreaser is made of nano oil-absorbing felt made of nano-scale polypropylene fiber polymer.

experiment example 2

[0059] The emergency system for highway bridge deck runoff purification is as in Example 1. For the bottom of the floating degreaser, choose nano oil-absorbing felt made of nano-scale polyester fiber polymer.

Abstract

The invention relates to a highway bridge deck runoff rainwater flood purification utilization and environmental risk emergency system, in particular to a highway bridge deck runoff purification emergency system with a floating oil removal function. The highway bridge deck runoff purification emergency system is divided into a pre-precipitation area, an oil removal area and a deep purification area through a partition wall, a first oil removal partition wall and a second oil removal partition wall, wherein the pre-precipitation area plays a main precipitation effect on suspended matters such as sediment in the rainwater runoff, the oil removal area is provided with a floating oil remover, special pollutants such as petroleum in the bridge deck runoff can be directionally removed, the deeppurification area realizes overall purification of runoff through a comprehensive process such as baffling precipitation, self-adsorption filtration and microbial decomposition, the discharged water can be used for the reuse function of greening irrigation and the like, and the intensive utilization of rainwater flood resource is realized.

Description

technical field [0001] The invention relates to a road bridge deck runoff rainwater purification utilization and environmental risk emergency system, in particular to a highway bridge deck runoff purification emergency system with a floating degreasing function. Background technique [0002] An important source of pollution that causes bridge deck runoff pollution is the motor vehicles running on the road. The source of vehicle pollution is the vehicle itself and its products, including vehicle exhaust, vehicle tires, gasoline, and lubricating oil leakage. Automobile exhaust contains a large amount of heavy metal pollutants such as Pb; automobile tires and road wear contain heavy metal pollutants such as Zn; leaked gasoline and lubricating oil contain toxic organic ring aromatic hydrocarbons and gasoline hydrocarbons. These substances are deposited on the road surface in sunny days, and will be washed by road surface runoff into nearby water bodies in rainy days, which can e...
