Ecological landscape type integrated garbage and sewage treatment system for villages and small towns

Abstract

The invention relates to the technical field of sewage treatment, in particular to an ecological landscape type integrated garbage and sewage treatment system for villages and small towns. The system comprises a grille well, an aeration adjustment pool, a garbage transfer station, a reinforced ecological pool and a plurality of earthworm natural decomposition pools connected in series, wherein the grille well is connected with the aeration adjustment pool through a sewage pipe, the aeration adjustment pool is connected with a flat-flow water distributor in the reinforced ecological pool through a pipeline, and the reinforced ecological pool is connected with the earthworm natural decomposition pools through pipelines; the earthworm natural decomposition pools are connected with one another through the sewage pipe; a gas collection pipeline is connected with a gas collection fan and is connected with the aeration adjustment pool through the gas collection fan and a gas pipeline, a water collection pit is connected with the aeration adjustment pool through a leachate pipe, and a rotary fan is connected with the aeration adjustment pool and an aeration pipe in the reinforced ecological pool through a pipeline. The system integrates garbage treatment and sewage treatment, has the environment beautifying function and treats rural garbage very well.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated village and town ecological landscape garbage sewage treatment system. Background technique [0002] Traditional village and town garbage transfer and sewage treatment are usually built separately, occupying a large area, wasting space, and bad operation will cause bad smell. Most of the existing rural sewage adopts integrated (glass fiber reinforced plastic, PE or carbon steel) A 2 O Process equipment directly discharges water or adds artificial wetland behind, traditional A 2 The O process does have the effect of nitrogen and phosphorus removal in theory, but due to various reasons such as investment costs and operation management, it is often difficult for most rural sewage to reach the first-class standard of urban sewage treatment plants after construction or commissioning and operation. .

[0002] Traditional village and town garbage transfer and sewage treatment are usually built separately, occupying a large area, wasting space, and bad operation will cause stench

Most of the existing rural sewage adopts integrated (glass fiber reinforced plastic, PE or carbon steel) A 2 O Process equipment directly discharges water or adds artificial wetland behind, traditional A 2 The O process does have the effect of denitrification and phosphorus removal in theory, but due to various reasons such as investment costs and operation management, it is often difficult for most rural sewage to reach the first-class standard of urban sewage treatment plants after the completion or commissioning and operation stage of ammonia nitrogen and total phosphorus.

Most of the garbage transfer stations in villages and towns have a lot of peculiar smell in the transfer stations, and the garbage leachate produced has not been treated, polluting the environment

Generally speaking, the current village and township garbage transfer and sewage treatment have the following problems: 1. The separate construction of village and township garbage transfer stations and sewage treatment stations occupies a large area of ​​land; 2. The garbage transfer station produces a large odor; The leachate produced by the sewage is very polluting and has not been treated; 4. After the treatment of village and town sewage, most of the nitrogen and phosphorus are difficult to maintain for a long time to meet the first-level standard of urban sewage treatment plants; 5. The village and town garbage transfer stations and sewage treatment stations will produce certain waste. Odor or even stench; 6. A large amount of sludge will be generated, which requires regular cleaning, which costs manpower, sludge treatment and transportation costs, and if it is not cleaned regularly, it will affect the indicators of the discharge water, and the total phosphorus will often exceed the standard; 7. Most of them cannot play a landscape role
