Did Typhoon Anbin have a significant impact on your facilities? It had a major impact on our wastewater treatment plant; although there is a separation between rainwater and sewage, the water level in the plant remained high, and oil spilled from the sewage wells surrounding the facility. What impact has this had on your company?
The oil leaking from the manhole covers by the road is caused by a high liquid level in the oil separation tank at the sewage inlet. Provisions should be made in advance to deal with such situations: ensure that all pumps start immediately, lower the liquid level in the emergency tanks, and also reduce the liquid level in the subsequent biological treatment tanks. The main problem is that an excessive amount of water can result in insufficient pumps for pumping wastewater out of the oil separation tank. Two more pumps were added to this system two years ago, bringing the total to four. Before it rains, bags should be used to block the drains in all relevant devices, thereby further reducing the amount of rainwater that enters
The volume of wastewater at our treatment plant is fixed; we lower the water level to its lowest point before it starts to rain. If it rains heavily, the water level rises sharply, resulting in an excessively high level
The rain flooded the tank area, and there were leaks in the high-temperature parts of some units; the rain was just too intense
The key issue is that the sewage system simply doesn’t have time to discharge the water; does it matter to you whether it’s urgent or not?
It just rained a little, and then it passed by again～(￣▽￣～)~
