rainwater and wastewater automatic separation device for rainwater and wastewater nonseparable house

摘要

The present invention provides an automatic rainwater and wastewater separation device for a house which cannot separate rainwater and wastewater, capable of preventing wastewater from being discharged to a rainwater pipe and preventing overload and excessive operation costs of a rainwater pump by preventing rainwater from flowing into a wastewater pump station. The automatic rainwater and wastewater separation device for a house which cannot separate the rainwater and the wastewater also can prevent an overflow accident of a wastewater manhole pump station. According to a proper embodiment of the present invention, the automatic rainwater and wastewater separation device includes: a rainwater and wastewater separation housing having a rainwater inlet formed in the upper part, a wastewater inlet located in the lower part of the rainwater inlet, a rainwater outlet, and a wastewater discharge control pipe installation port, wherein the wastewater inlet and the rainwater outlet are located at a same height and the wastewater discharge control pipe installation port is located to be lower than the rainwater outlet; a wastewater inflow connection pipe connected to the wastewater inlet and enabling dishwater to flow into the rainwater and wastewater separation housing; a rainwater outflow connection pipe discharging the rainwater reaching the rainwater outlet; a wastewater discharge control pipe individually having a wastewater opening and closing port at one end and a wastewater outlet at the other end and installed in the wastewater discharge control pipe installation port, wherein the wastewater opening and closing port in the wastewater discharge control pipe is located to be lower than the wastewater discharge control pipe installation port in the rainwater and wastewater separation housing and the wastewater outlet at the other end is located outside the rainwater and wastewater separation housing; and a valve unit installed in the wastewater discharge control pipe and opening and closing the wastewater opening and closing port in accordance with a water level in the rainwater and wastewater separation housing. The valve unit opens the wastewater opening and closing port in a case that the water level in the rainwater and wastewater separation housing is equal to or is less than a wastewater discharge installation port. The valve unit closes the wastewater opening and closing port as the water level of the rainwater and wastewater separation housing is higher than the height of the wastewater discharge installation port in a case of rain.
