Abstract

A comprehensive treatment device for highway runoff pollution of a water resource protection area comprises a road surface runoff chute, a physical filter tank, a physical adsorbing tank, a chemical treatment tank, a biochemical tank, a slope surface runoff chute and a drop manhole. The physical filter tank, the physical adsorbing tank, the chemical treatment tank and the biochemical tank are sequentially connected in series and communicated. The road surface runoff chute is communicated with the physical filter tank, a guide flow wall is disposed in the biochemical tank provided with a wateroutlet, the physical filter tank is further provided with an overflow port communicated with the biochemical tank, and the slope surface runoff chute is communicated with the drop manhole which is connected with the biochemical tank. The comprehensive treatment device for highway runoff pollution of the water resource protection area has the advantages of being simple in structure, simple and convenient to maintain, capable of effectively lowering concentration of suspended solid particles, oil, heavy metal and the like in road surface runoff, also capable of performing emergency treatment onleakage of toxic substances in emergencies, reducing effect of road surface runoff on surrounding soil and water, and enabling treated highway runoff stored in the biochemical tank to be used for irrigation and the like.

Description

technical field

[0001] The invention relates to the technical fields of highway traffic engineering and environmental protection, in particular to a comprehensive treatment device for highway runoff pollution in water source protection areas. Background technique

[0002] In the field of highway traffic engineering, with the rapid development of traffic facilities, a large number of issues such as the impact of highways on the surrounding environment have emerged, and the problem of water resource protection around expressways has become increasingly prominent. Studies at home and abroad have shown that many pollutants such as petroleum, heavy metals (Cu, Pb, Zn, etc.), suspended solid particles or ions will be deposited during highway operation, and the road surface runoff formed by rainfall washing the road surface will pollute surface water and groundwater. To a great extent. Most road constructions are distributed linearly and inevitably cross some important rivers, tou...

Embodiment Construction

[0022] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] like figure 1 and figure 2 As shown, a comprehensive treatment device for road runoff pollution in water source protection areas includes a physical filter tank 2 connected to the road surface runoff torrent tank 1, a physical adsorption tank 3, a chemical treatment tank 4 and a biochemical tank The drop water well 16 that water outlet 15 links to each other. The depths of the pools are the same but the depths of the designed water outlets are inconsistent. The depths of the overflow 8, the second water outlet 7 and the third water outlet 9 are all lower than the depth of the water inlet 1 of the road surface runoff rapid flow tank, forming a height difference so that the water flow unimpeded.

[0024] The road surface runoff flows in from the water inlet of the road surface runoff rapid flow tank 1, and the grid 13 ar...
