Hazardous chemical leakage monitoring and emergency treatment system for sensitive water body bridge section

Abstract

The invention relates to a hazardous chemical leakage monitoring and emergency treatment system for a sensitive water body bridge section. The system mainly comprises a hazardous chemical leakage emergency monitoring system, a bridge surface runoff collection system, a hazardous chemical emergency storage system and a bridge surface runoff treatment system. When a traffic accident does not happenon the bridge section, bridge surface runoff initial rainwater enters a collection pipeline system, and directly flows into the bridge surface runoff treatment system for purification treatment afterpassing through a runoff electric butterfly valve switch of an emergency regulating pondage, and 30 minutes later, the bridge surface runoff is directly discharged through an overflow port of the emergency regulating pondage. When the traffic accident happens on the bridge section, firstly, the traffic accident is discovered through a bridgehead monitoring camera and an alarm telephone, and whether hazardous material leakage exists is determined; secondly, an emergency control system is started by a monitoring center, and the emergency electric butterfly valve switch in the runoff regulating pondage is turned on; and finally, the leaked hazardous material and a diluent thereof enter the regulating pondage through a collection pipeline and then directly flow into an emergency storage pool.

Description

technical field [0001] The invention relates to the technical field of dangerous goods leakage emergency and initial rainwater treatment of bridge deck runoff in the water environment protection project of highway crossing sensitive water body sections, specifically a kind of dangerous goods leakage monitoring, emergency storage and The emergency treatment system for the initial rainwater treatment function of bridge deck runoff. Background technique [0002] With the rapid development of the national economy, the highway network construction is becoming more and more perfect. There are more and more highway bridge sections across sensitive water bodies. The fast, convenient and flexible transportation characteristics of the highway network make more and more hazardous chemicals As goods enter the expressway transportation network, the probability of accidents of vehicles transporting dangerous goods in sensitive water body road sections also increases, thus bringing more an...
