High separation rate oil -water separator

The utility model discloses a high separation rate oil -water separator, it includes open -top the standpipe of intaking (1) and drainage standpipe (2), and intake standpipe and drainage standpipe pass through U type curved (3) intercommunication, and the standpipe lateral wall of intaking is equipped with water filling port (4), and the adaptation had gate valve (5) that can reciprocate in the U type was curved, and water filling port below adaptation has aeration pipe (6) in the standpipe of intaking, and the rigid coupling has horizontal filter screen (7) on the standpipe of intaking between the water filling port is managed with the aeration. The beneficial effects of the utility model are that utilize the sewage that the gate valve will be pending to keep apart in the standpipe of intaking and maintain certain liquid level height, take the fluid in the sewage to the sewage surface behind the aeration aeration of pipe a period, reopen and open the gate valve, the sewage that is separated gets into the drainage standpipe, emit into the biochemical treatment workshop again in the follow drainage standpipe, the clean separation of fluid and sewage has been guaranteed, and can get rid of other the small granule impurity in the sewage, water oil separating is efficient, moreover, the steam generator is simple in structure, therefore, the carrier wave prepaid electric energy meter is low in cost.
