Experimental device for studying improvement of water quality of water body by intermittent aeration and use method of experimental device

Abstract

The invention belongs to the technical field of water quality improvement, and particularly relates to an experimental device for researching improvement of water quality by intermittent aeration and a use method thereof. The device comprises an upstream water distribution area, a main body reaction area and a downstream water return area which are sequentially connected, a water outlet of the downstream water return area is provided with a water return peristaltic pump, and the water return peristaltic pump lifts water flowing to the downstream water return area to the upstream water distribution area through a water return pipeline to form circulation; the main body reaction area comprises an aeration area and a deposition area which are integrally arranged from top to bottom, an aeration device and a water body sampling device are arranged in the aeration area, a sludge sampling device is arranged in the deposition area, the water body sampling device and the sludge sampling device are symmetrically arranged on the front wall and the rear wall of the main body reaction area, and a plurality of groups of water body sampling devices and sludge sampling devices are arranged in the vertical direction of the front wall and the rear wall. The invention aims at improving the water quality of the damaged river, provides a set of complete experimental device and research method for improving the water quality of the damaged river, and has great significance for protecting the water environment of the river.

Description

technical field [0001] The invention belongs to the technical field of river water quality improvement, and in particular relates to an experimental device and a use method for studying intermittent aeration to improve water quality. Background technique [0002] The development of human society is closely related to rivers. The natural functions of rivers include hydrological functions, geological functions and ecological functions. Rivers are one of the most important ecosystems on the earth. In recent years, my country has made great progress in water environment protection. The input of exogenous pollutants in most river water environments has been effectively controlled. At this stage, the focus of improving river water quality should be how to solve the endogenous pollution of river ecosystems. direction. [0003] The purpose of improving the water quality of damaged rivers is not only to restore the polluted rivers to their original state, but to make the rivers meet ...

Problems solved by technology

However, in the face of the diversity and complexity of the river ecological environment, how to use a unified experimental device to study the changeable river ecosystem is still one of the problems that plague scholars in related fields at home and abroad.
