Dynamic sewage flocculation evaluation device

Abstract

The invention relates to a dynamic sewage flocculation evaluation device, which comprises a sewage pump, a material pumping pump, a sewage storage tank, a flocculating agent preparation tank, a sewage head tank, a flocculating agent head tank, a coagulating basin, a flocculation basin, a settling basin, a buffer basin and a clarifier basin. The coagulating basin, the flocculation basin, the settling basin, the buffer basin and the clarifier basin are sequentially communicated, the coagulating basin and the flocculation basin are separated through a movable retaining plate, the flocculation basin and the settling basin are separated through a movable retaining plate, a motor-driven stirrer is installed in the coagulating basin, a reverse flocculation retaining plate is installed in the flocculation basin, an orthokinetic flocculation retaining plate is installed in the settling basin, and a water purification filter device is installed in the clarifier basin. The dynamic sewage flocculation evaluation device solves the problems that the existing flocculating agent evaluation methods are all still water flocculation settling methods and are not suitable to actual requirements of a sewage treatment process, is the evaluation device of dynamic sewage flocculation effects, can detect flocculation performance of the flocculation agent under dynamic water state, can truly reflect using effects of the flocculation agent and is suitable to the field of sewage treatment.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a dynamic sewage flocculation evaluation device. Background technique [0002] Sewage generally includes domestic sewage and industrial sewage. From 2005 to 2011, the national sewage treatment capacity increased from 79.9 million tons per day to 141.54 million tons per day, with an average annual increase of 11%; the sewage treatment rate increased from 52% to 74%, with an average annual increase of 5.2%. With the acceleration of urbanization and the improvement of people's living standards, the discharge of urban domestic sewage continues to increase. In 1999, my country's urban domestic sewage discharge surpassed industrial wastewater for the first time, becoming the main source of pollution of the water environment, and the demand for domestic sewage treatment industry is huge. In 2011, the urban domestic sewage discharge amounted to 41.97 billion tons, a year-on-year...
