Problems solved by technology

[0002]At present, conventional urban sewage treatment facilities require large investment, high operating costs, and complex operation management, making it difficult to meet the sewage treatment requirements of small towns in mountainous areas
In recent years, the falling water aeration technology for sewage treatment has developed rapidly. For example, 200910104686.8 "Subsurface Flow Constructed Wetland Sewage Treatment System Utilizing Falling Water Aeration and Oxygenation" and 200510123147.0 "Anaerobic Falling Water and Oxygenation Artificial Wetland combined small-scale sewage phosphorus and nitrogen removal method" and 200910104273.X "a sewage treatment method suitable for small towns in mountainous areas", etc., but the above-mentioned falling water aeration sewage treatment technology structures are all concentrated in plants and require special land for sewage plants. It occupies a large area; and does not have the function of sewage transportation

Embodiment Construction

[0022] see figure 1 , figure 2 , Figure 3A and Figure 3B and Figure 4 , The falling water aeration type sewage treatment channel is composed of a perforated cover plate 1 , fillers and a channel main body 8 . A plurality of partition walls 2 and 3 are arranged along the water flow direction in the channel main body 8, and the channel main body is divided into a plurality of processing units. The height of the bottom of each processing unit decreases successively. Oxygenation is strengthened, and there is a water outlet 5 under the partition wall 3 to prevent short flow. Between the adjacent partition wall 2 and the partition wall 3 is a stepped canal bottom 6 with a certain slope. And the canal bottom 6 in each treatment unit is also a stepped structure with at least one step downwards, and the lowest step of each treatment unit is a water collection stagnation area 7 . Granular iron-rich and calcium-rich fillers 10 are set in the water flow collection retention area...

Abstract

The invention discloses a drop-aeration sewage transportation treatment channel, and the channel comprises a channel main body, fillers, and an opening cover plate. The channel adopts stepped drop; a partition wall is disposed in the channel main body part, and the channel main body is divided into several treatment units; hole openings are disposed on the partition wall; a certain gradient is disposed at the channel bottom; the channel is filled with suspending fillers; the opening cover plate is disposed on the channel main body. The channel integrates the two functions of sewage transportation and purification as a whole, and has the advantages of simple process, high treatment efficiency, no operation energy consumption, less land occupation, low investment and convenient management.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a water drop aeration type sewage transport and treatment channel. Background technique [0002] At present, conventional urban sewage treatment facilities require large investment, high operating costs, and complex operation and management, making it difficult to meet the sewage treatment requirements of small towns in mountainous areas. In recent years, falling water aeration technology for sewage treatment has developed rapidly. Wetland combined small-scale sewage phosphorus and nitrogen removal method" and 200910104273.X "a sewage treatment method suitable for small towns in mountainous areas", etc., but the above-mentioned falling water aeration sewage treatment technology structures are all concentrated in plants and require special land for sewage plants. It occupies a large area; and it does not have the function of sewa...
