When industrial and mining enterprises have other accidents such as fire disasters, fire-fighting wastewater can be generated, the pollutant components are complex, and the fire-fighting wastewater is discharged into urban rivers and lakes along with rain ditches in a factory area to seriously affect the water quality of the urban rivers and lakes.
At present, two methods, namely time control (automatic or manual) and liquid level control, are commonly adopted for collecting initial rainwater and fire-fighting wastewater. The time control is mainly manually controlled, a valve entering the initial rainwater collecting pool is opened when raining, and the valve is closed after 10min or 15min, so that the initial rainwater cannot completely enter the collecting pool due to the limitation of responsibility and operation time because of manual control; and set up the reposition of redundant personnel well before the liquid level control initial stage rainwater collecting pit, open the liquid level elevation of collecting pit chain with the switching valve, open or close through the liquid level control valve who sets for, realize that initial stage pollution rainwater and clean rainwater of later stage shunt naturally, secondly, liquid level control does not need manual control, convenient operation, nevertheless need use electrical equipment such as electric valve and liquid level control device, the fault rate is high, invests in greatly.
In conclusion, because the initial rainwater catchment area of the industrial and mining enterprises is large, two conventional initial rainwater collection methods cannot completely collect the initial rainwater or the fire-fighting wastewater, so that part of the initial rainwater or the fire-fighting wastewater directly enters the urban river and lake water system to cause water pollution.
In the prior art, chinese patent publication No. CN206873605U discloses an automatic operation initial rainwater collecting tank, which is suitable for collecting initial rainwater, emphasizes on the pretreatment of initial rainwater, and reduces the load of subsequent sewage treatment facilities after pretreatment by sand deposition and oil removal, but cannot reduce the collection amount of treated rainwater and the load of subsequent sewage treatment facilities; also for example, chinese patent publication No. CN208071347U discloses a fire-fighting wastewater collection tank for chemical production, which is suitable for collecting fire-fighting wastewater, and pays attention to the automatic cleaning and operation of the collection tank, and has numerous devices, complicated operation, and complex management, and cannot realize the automatic collection of fire-fighting wastewater, and there is a possibility of fire-fighting wastewater leakage.
