Water source protecting area highway runoff collecting and emergency purifying system

Abstract

The invention relates to the technical field of environmental protection and water purification, in particular to a water source protecting area highway runoff collecting and emergency purifying system. The system comprises a flow distribution pool, a physical adsorption pool, an emergency storage pool and a grass planting ecological pool. The flow distribution pool, the physical adsorption pool,the emergency storage pool and the grass planting ecological pool sequentially communicate in series. The flow distribution pool communicates with a road surface runoff water input pipe, a later-period runoff water output pipe, a flow distribution pool water output pipe and a flow distribution pool check valve, and a rapid starting and closing valve is arranged in the flow distribution pool. The physical adsorption pool communicates with a physical adsorption pool water output pipe, and multiple layers of activated carbon plates are arranged in the physical adsorption pool. The emergency storage pool communicates with an emergency storage pool water output pipe and an emergency water input pipe, and a valve well and a bidirectional emptying valve are arranged in the emergency storage pool.The grass planting ecological pool communicates with a grass planting ecological pool water output pipe, a flow guide wall and a fine stone baffle are arranged in the grass planting ecological pool,and aquatic ecological plants are planted on the bottom of the pool.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and water purification, in particular to a road runoff collection and emergency purification system in a water source protection area. Background technique [0002] With the continuous improvement of the road network, the safety issues of the road and the surrounding environment have gradually emerged, especially when the expressway crosses environmentally sensitive areas such as water source protection areas, the importance of water environment protection is self-evident. Studies by a large number of experts and scholars have shown that vehicles will leave a large amount of pollutants on the road during driving, mainly including exhaust gas, oil pollution, and heavy metals. severe impact. At the same time, for vehicles carrying various dangerous goods, if an accident occurs that causes toxic and harmful substances to leak into the waters of the protected area, it will be an irr...

Problems solved by technology

[0003] At present, my country has carried out some research on the pollution mechanism and treatment of highway runoff, but there are few studies on highway runoff collection and emergency purification systems, especially for road surface runoff collection in areas with strict discharge standards such as water source protection areas.
