Expressway deck runoff treatment and accident emergency system and method thereof

Abstract

The invention discloses an expressway deck runoff treatment and accident emergency system, which comprises the following parts: a treatment unit, a remote proximity card arranged on a hazardous chemical transportation vehicle, card readers arranged at front and back ends of a bridge, a control system and each electromagnetic valve controlled by the control system. The system disclosed by the invention is used for carrying out oil, water and solid separation on rainwater runoff on the deck, the occupied space is small, the efficiency is high, the system can be arranged nearby at two sides of the bridge, sewage can be treated in time, the quality of directly discharged water can meet requirements of environmental protection, and the system is particularly suitable for expressway bridges. The system can also meet the requirements of environmental protection in extreme severe weather such as rainstorm. A conducting valve is controlled to be opened and closed in three different work states: the normal state, the preparation state and the emergency state, so pre-warning and preparation for dealing with accidents can be realized; even under the condition of no monitoring by personnel, any chemical does not leak after a leakage accident of hazardous articles occurs, and risks of polluting water sources such as rivers and lakes are eradicated.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a highway bridge deck runoff treatment and accident emergency system and method thereof. Background technique [0002] There are a large number of bridges and super-large bridges built in the expressway network to cross rivers, lakes and canyons. The water quality safety of the surface water body or drinking water source under the bridges is directly related to people's health, social stability and economic development, and is seriously related to social Public safety and livelihood issues. [0003] A large number of studies at home and abroad have shown that due to factors such as atmospheric subsidence, traffic flow, and road surface roughness, bridge deck rainwater runoff contains a large amount of suspended solids, organic pollutants, nutrient salts, heavy metals, polycyclic aromatic hydrocarbons, and oils. After these pollutants enter the receiving water bo...

AI Technical Summary

Problems solved by technology

[0005] The applicant aims at the disadvantages of using a fixed pool body for the above-mentioned existing highway bridge deck runoff treatment, which cannot be flexibly adapted to various infrastructure environments, and the emergency treatment is lagging behind, and there are hidden dangers of pollution. Accident emergency system and its method, so that the modularization of processing units can be realized, and the early warning and preparation of accident hidden dangers can be carried out in advance
