Abstract

The invention discloses a physical and chemical treatment system for hazardous waste. A shaft sleeve is rotatably arranged on the inner wall of the flow sensor cover, and a shaft rod is connected to the flow sensor shaft sleeve by axial sliding. The upper end of the shaft of the flow sensor extends to the outside of the cover. The cover of the flow sensor is provided with a through hole for the shaft to slide axially and is sealed with the shaft. Push the vane that drives the shaft sleeve to rotate. The shaft of the flow sensor is covered with a spring. One end of the spring of the flow sensor is connected to the shaft sleeve, and the other end is connected to the side wall of the shaft. The lower end of the shaft of the flow sensor extends into the basket filter element. The bottom is provided with an impeller, and the side wall of the shaft rod of the flow sensor is provided with bristles in contact with the inside of the basket filter element.

Description

technical field [0001] The invention relates to the technical field of waste liquid treatment, in particular to a hazardous waste liquid physical-chemical comprehensive treatment system. Background technique [0002] Hazardous wastes are of various types, with complex components and large fluctuations in properties. At present, the technologies adopted at home and abroad mainly include heat treatment, physical and chemical treatment, comprehensive utilization and solidification landfill. For liquid hazardous waste with low calorific value and low COD value, physical and chemical treatment is often used. [0003] The Chinese patent with the application number: 201721109881.6 discloses a physical and chemical treatment system for hazardous waste, including a storage unit for classified storage of hazardous waste raw materials, for comprehensive reactions of acid-base neutralization, reduction and chemical precipitation unit, flocculation sedimentation unit, demulsification u...
