The invention discloses a device for removing oil slick in wastewater based on an ultrasonic liquid level meter and pressure sensors. The device comprises an oil-free water tank, an oil slick sand settling tank, an inclined plate sedimentation zone, a sand settling zone, a sewage water distribution pipe, an oil slick receiving box, a first wireless pressure sensor, a horizontal ejector, a second wireless pressure sensor, an oil slick zone, the wireless ultrasonic level meter and the like; due to the adopted wireless pressure sensors and wireless ultrasonic level meter, the complicated wiring and unreliability caused by the line fault in engineering are reduced and the wiring cost is reduced. Since the wireless ultrasonic level meter is also arranged in the device disclosed by the invention, by virtue of the synergistic effect of the wireless pressure sensors and the wireless ultrasonic level meter, whether the oil slick partially or completely covers the oil slick zone or not is indirectly determined, when the oil slick completely covers the oil slick zone, the oil slick layer floating on the water surface located at the upper part of the oil slick sand settling tank can be automatically removed. The device disclosed by the invention has the advantages of more simple and concise structure, and convenience in manufacturing and installation.
Description
technical field [0001] The invention belongs to the technical field of oily wastewater treatment, and in particular relates to a device for removing floating oil in wastewater based on an ultrasonic liquid level gauge and a pressure sensor. Background technique [0002] Oily substances enter the water through different channels to form oily wastewater. Due to its large volume and wide area, and the characteristics of being difficult to treat, it becomes a kind of seriously harmful wastewater. Its sources mainly include: petroleum exploration and oil processing in the petroleum industry , extraction, storage and transportation; car washing in the transportation industry, oily wastewater discharged from oil washing tanks in railway locomotive depots; rolling water, lubricating oil and other wastewater mainly emulsified oil produced in the process of machinery manufacturing; in addition, the catering industry , textile industry, food processing industry and other manufacturing ...
