Rotary microporous aeration circular coil system for treating sewage

Abstract

The invention relates to a rotary microporous aeration circular coil system for treating sewage, belonging to the field of microporous aeration pipe equipment for treating the sewage. The rotary microporous aeration circular coil system is characterized in that: each microporous concentric circular coil group consists of a vertical rotating main pipe and a horizontal microporous concentric coil, wherein the horizontal microporous concentric coil is an integral coil which is formed by connecting a plurality of microporous concentric circular pipes from the inside out with microporous communicating pipes which are radially and uniformly arranged between the adjacent inner circular pipes and outer circular pipes at intervals; the central inner circular pipes of the coil are communicated with the vertical rotating main pipe through the microporous communicating pipes which are radially arranged at intervals; a plurality of microporous concentric circular coil groups are arranged intervals; and the upper ends of the rotating main pipes in all groups are connected with rotation drivers and control mechanisms respectively, and the lower ends of the rotating main pipes are communicated with gas transmission branch pipes respectively to form the rotary microporous aeration circular coil system. The rotary microporous aeration circular coil system greatly improves the aeration efficiency, ensures that oxygen dissolved in water bodies in a whole aeration tank is more uniformly distributed, reduces the operating cost of the aerobic process, and realizes the high-efficient and low-energy consumption operation of the aeration tank.

Description

technical field [0001] The invention relates to a rotary microporous aeration ring coil system for sewage treatment, which belongs to the field of microporous aeration pipe equipment for sewage treatment. Background technique [0002] As one of the important means of water pollution control, sewage treatment is of great significance to the improvement and improvement of water environment quality. At present, there are common problems in the operation of urban sewage treatment plants, such as excessive energy consumption and high operating costs. Many sewage plants are "affordable to build, but unaffordable to use". Studies have shown that an average of 80% of the energy consumption of urban sewage plants is concentrated in the necessary aerobic treatment process in the sewage treatment process. Improving the efficiency of the aeration system for aerobic treatment is the key to achieving high-efficiency and low-consumption operation of sewage plants. Commonly used aeration m...

Problems solved by technology

In the actual operation of the aeration tube, there are often the following problems: (1) The horizontal distribution of dissolved oxygen in the water body after aeration is uneven

The commonly used microporous aeration tubes are linear and all tubes are installed parallel to the same plane during installation, so the upward trajectory of the microbubbles generated by each aeration tube in the water is a straight line parallel to each other, so the agitation of the microbubbles in the longitudinal direction The force is not strong, and the turbulent diffusion of bubbles is weak, which leads to the uneven distribution of dissolved oxygen in the water body of the aeration tank in the longitudinal direction after aeration, which affects the treatment effect and increases the treatment energy consumption; (3) In actual installation, the micro The higher density of hole aeration pipe arrangement leads to higher investment

In order to solve the above-mentioned uneven distribution of dissolved oxygen in the water body after aeration, when the equipment is installed, in order to make the microporous aeration bubbles cover the entire aeration tank as much as possible, the method of increasing the arrangement density of the microporous aeration tubes is often adopted However, this will lead to an increase in engineering costs and the distribution of dissolved oxygen in the water body is still uneven from the actual operation effect of each sewage plant
