Multifunctional sewage purification device

Abstract

The invention belongs to the technical field of multistage treatment of sewage, and particularly relates to a multifunctional sewage purification device. The multifunctional sewage purification devicecomprises a stand and a cleaning barrel, wherein a water feeding pipe and a water discharging pipe are arranged on the cleaning barrel; a first valve is arranged on the water feeding pipe; a filter plate is arranged in the cleaning barrel; a piston cylinder is further fixedly arranged on the side wall of the cleaning barrel; a piece of oil filter cloth is arranged at a connection joint of the water discharging pipe and the cleaning barrel; a resistance wire is arranged in the oil filter cloth; a flexible oil discharging pipe is arranged below the oil filter cloth, and is connected with an oiltank; a second valve is arranged on the flexible oil discharging pipe; a first spring is connected between the oil tank and the stand; a first switch, a second switch and a third switch are arrangedon the stand; the oil tank is connected with the oil discharging pipe; a third valve is arranged on the oil discharging pipe; the inner wall of the water discharging pipe is connected with a turbine in a rotatable manner; one side of the turbine is connected with a swing rod in a rotatable manner; the other side of the turbine is connected with a cam. The multifunctional sewage purification devicecan perform multistage treatment on the sewage; furthermore, in a treatment process, blockage of the water feeding pipe by sediment is avoided; the multifunctional sewage purification device is mostly applied to treatment of the sewage.

Description

technical field [0001] The invention belongs to the technical field of multistage treatment of sewage, and in particular relates to a multifunctional sewage purification device. Background technique [0002] In the process of oil and gas fields and petrochemical production, a large amount of oily sewage is produced. The oily sewage contains oily crude oil, suspended solids and other complex mineral impurities, which must be treated; direct discharge will pollute the environment, and direct reinjection will cause formation pollution. [0003] For this reason, Chinese patent CN105084568A discloses an oily sewage treatment device, which includes a sewage treatment tank, a sludge collection assembly and an oil absorption assembly. The bottom of the sewage treatment area in the sewage treatment tank is connected with a sewage water inlet. The bottom of the sludge collection assembly communicates with the sludge outlet, and the collection port of the sludge collection assembly is...

Problems solved by technology

[0004] However, there are the following problems in the above-mentioned patent: the sewage flows out from the water inlet at the bottom through a series of treatments and flows out from the purified water outlet at the top. During this process, the sludge contained in the sewage will block the water inlet at the bottom, thereby affecting the normal flow of sewage. purification process
