Industrial sewage staged treatment and discharge device

Abstract

The invention discloses an industrial sewage staged treatment and discharge device, which comprises a treatment box, wherein the treatment box is internally divided into a precipitation cavity, an oil removal cavity and a desalting cavity by a plurality of partition plates from top to bottom, an impurity content measuring component is arranged at the water inlet end of the precipitation cavity, a precipitate discharge component is arranged at the bottom of the precipitation cavity, a flow-limiting drainage component is arranged at the water outlet end of the precipitation cavity, the water inlet end of the oil removal cavity is provided with a first transmission pipe which is in through connection with the precipitation cavity, the outer wall of the first transmission pipe is provided with a sewage oil content measuring component, the top of the inner wall of the oil removal cavity is provided with a floating oil absorbing and removing component, the water inlet end of the desalting cavity is provided with a second transmission pipe which is connected with the oil removal cavity in a penetrating manner, the outer wall of the second transmission pipe is provided with a sewage salt concentration measuring component, and a desalting component is arranged in the desalting cavity. The industrial sewage staged treatment and discharge device is convenient for detecting the impurity content, the grease content and the salt concentration in sewage and is convenient for stage treatment according to the actual condition of the sewage.

Description

technical field [0001] The invention mainly relates to the technical field of sewage treatment, in particular to an industrial sewage grading treatment and discharge device. Background technique [0002] Industrial wastewater includes production wastewater, production sewage, etc. It refers to the wastewater and waste liquid generated in the industrial production process. The harmless treatment of industrial wastewater is an important task before wastewater discharge. [0003] According to a classification treatment device for industrial sewage provided by the patent document with the application number CN202010880696.7, the product includes a sedimentation tank and a treatment tank, and the outer wall of the sedimentation tank is fixedly connected to the position near the top with a water inlet pipe, and between the sedimentation tank and the treatment tank A water-passing pipe is arranged between them, a water outlet pipe is fixedly connected to the lower middle of the out...
