Embodiment

[0021] As shown in Figure 1: the main body of the pumping aerator (4) is a rigid straight cylinder, the inlet (3) of the pumping aerator is trumpet-shaped, and the outlet is a sliding cylinder (5), which can automatically float with the change of the water level , the diameter of the lower part of the sliding cylinder is smaller, and the diameter of the upper part is enlarged. The compressed air pipe (1) is connected to the lower end of the water pumping aerator (4). The pumping aerator is fixed on the bottom of the reservoir (lake) with an anchor pier (2). A straight air guide cylinder (8) with both ends open is installed in the enlarged diameter part of the sliding cylinder (5) of the pumping aerator, and an air storage cover (7) with an open lower end and a closed top is buckled upside down on the upper part of the air guide cylinder. , the diameter of the air storage cover (7) is greater than the diameter of the air guide cylinder (8), and is fixed by welding with at leas...

Abstract

The invention discloses a water source quality improving apparatus which includes water lifting-aerating apparatus, distributing system. The water lifting-aerating apparatus connects an active carbon absorbing apparatus which loads active carbon by distributing system. The water lifting-aerating apparatus lifts the lower water body to the surface by compressing air to form water body cycle mixing and transport and distribute to the active carbon area. The contamination is removed by active carbon adsorption. The water lifting-aerating apparatus charges oxygen to the water body at the same time. The distributing system collects and distributes the offgas of the water lifting-aerating apparatus to the active carbon area to float the active carbon in order to make the water body flow through the active carbon area and fully contact with it. The invention is used for charging oxygen into water body and removing contamination with a high concentration and reducing the chroma and smell in the composite reservoir or upper or lower water layer of lake. It solves the problem of water quality restoration in suit, which is polluted with a high strength or burstiness in water source reservoir.

Description

technical field [0001] The invention relates to a water quality improvement device, in particular to a water quality improvement device organically combined with a hydraulic mixing aeration device and an active carbon adsorption device. Background technique [0002] Water sources, 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...
