Embodiment Construction

[0016] The main body of the provided pumping aerator 4 is a straight cylinder, the inlet 3 of the pumping aerator is located at the bottom of the reservoir (lake), the outlet 5 of the pumping aerator is close to the surface layer of the reservoir (lake), and is located at the bottom of the biological contact oxidation device 30, The outlet 5 of the pumping aerator is in a horizontal direction. The pumping aerator 4 is fixed on the bottom of the reservoir (lake) with an anchor pier. The provided biological contact oxidation device 30 is composed of biological filler 14 , upper and lower supports 17 , 13 of biological filler and floater 20 of biological filler. The biological filler is a fibrous central rope type three-dimensional elastic filler, which is vertically suspended and fixed between the upper and lower supports of the biological filler. The planes of the upper and lower brackets are circular, and are composed of a series of radial angle steels 18 and circular round s...

Abstract

The present invention discloses one kind of combined water quality improving apparatus with aerating water and biological contact oxidation. The combined water quality improving apparatus includes water sprinkling aerator in the lower part, biological contacting oxidation stuffing unit in the upper par, and air distributing system in between. The water sprinkling aerator inflates oxygen into water with compressed air and distributes lower layer water to biological contacting oxidation stuffing area, and the air distributing system collects the tail air and distributes it to the biological stuffing area. The present invention is used in mixing upper and lower water layers in reservoir or lake to aerate water, oxidize and degrade organic matter, and oxidize and eliminating Fe and Mn.

Description

technical field [0001] The invention relates to a water quality improvement device, in particular to a water quality improvement device combining a hydraulic mixing aeration device and a biological contact oxidation device. Background technique [0002] Reservoirs and lakes have large capacity, large water depth, and low fluidity, which bring some negative impacts. Due to the large water depth and low fluidity, it is easy to form water stratification phenomenon, that is, in summer, the water body with high temperature and light density is stably distributed in the upper layer, and the water body with low temperature and high density sinks to the bottom of the reservoir (lake); in winter, the opposite is true. Water bodies with extremely low temperature (less than 4°C) and light density are distributed in the upper layer of the water body, while water bodies with higher temperature (close to 4°C) and high density sink to the bottom of the reservoir (lake), resulting in relati...
