Abstract: The present invention relates to a system for treating hazardous chemicals. The system is capable of preventing environmental pollution by neutralizing a chemical substance leaking out of a storage tank before flowing into a wastewater treatment plant. According to the present invention, the system is to treat hazardous chemicals leaking out of storage tanks disposed in a discharge wall and disposed in a region limited by a flow path. A first on-off valve is installed in a chemical treatment furnace for connection between the flow path and a wastewater treatment plant. A second on-off valve is installed in a rainwater discharge path branching from the chemical treatment furnace. In the chemical treatment furnace, a pH adjustment unit is connected between the flow path and the first on-off valve. As a result, the pH of the chemical substance leaking out of at least one of the storage tanks is neutralized and then the substance is moved to the wastewater treatment plant. The first on-off valve, the second on-off valve, and the pH adjustment unit are configured to be capable of wirelessly communicating with a control unit. In a case where chemical leakage is detected in at least one of the storage tanks, a leakage detection means installed in the discharge wall primarily detects the leakage, the change values of level gauges individually installed in the storage tanks are measured, and the change values of flow gauges individually installed in pipes connecting the storage tanks and process facilities are measured. And then, the level gauge and flow gauge change values are compared for secondary recognition of the leakage amount and source.
