沉砂调节水解酸化池2出水自流进入第一级UASB＋AF厌氧池池底区的布水器，布水器将污水分布予高活性厌氧污泥床和厌氧复合床反应区，从而对污水中的高浓度有机物进行处理，处理后的污水流入调压池，再依次经第二级DSFF厌氧池、调压池和第三级AF厌氧池处理；在三级厌氧池内厌氧菌的作用下分解污水中的大部分有机物；处理后的污水流至人工湿地；The effluent from sand settling adjustment hydrolysis andacidification tank 2 flows into the water distributor in the bottom area of the first-stage UASB+AF anaerobic tank. The high-concentration organic matter in the tank is treated, and the treated sewage flows into the pressure regulating tank, and then goes through the second-level DSFF anaerobic tank, the pressure regulating tank and the third-level AF anaerobic tank for treatment; in the third-level anaerobic tank, anaerobic bacteria Under the action of decomposing most of the organic matter in the sewage; the treated sewage flows to the constructed wetland;

人工湿地通过模拟和强化自然湿地功能，将污水有控制地投配到湿地填料，湿地表面种植水生植物，污水沿一定方向流动的过程中，在填料、植物及微生物的物理、化学和生物的三重作用下，污水中污染物质通过填料过滤、植物吸收、微生物吸附降解来实现对污水的高效净化，污水中有机污染物和杂质在植物、土壤的吸附吸收作用下基本上在该段被去除，出水可直接用于农灌；By simulating and strengthening the functions of natural wetlands, constructed wetlands distribute sewage to wetland fillers in a controlled manner, and aquatic plants are planted on the wetland surface. During the process of sewage flowing in a certain direction, the physical, chemical and biological effects of fillers, plants and microorganisms occur. Under the action, the pollutants in the sewage are efficiently purified by the filler filtration, plant absorption, and microbial adsorption and degradation. The organic pollutants and impurities in the sewage are basically removed in this section under the adsorption and absorption of plants and soil. Can be directly used for agricultural irrigation;

人工湿地出水进入污泥沉淀池6，经污泥沉淀池6沉淀后的清水自流进入过滤池7，去除污水中残存的有机物；过滤池7过滤后的水进入回用水池9中进行蓄水。The effluent from the constructed wetland enters thesludge sedimentation tank 6, and the clean water after sedimentation in thesludge sedimentation tank 6 flows into thefilter tank 7 to remove the residual organic matter in the sewage; the filtered water in thefilter tank 7 enters thereuse tank 9 for water storage.

在另一个实施方式中，采用土地替换湿地。In another embodiment, land is used to replace wetlands.

本实用新型将物理与生化组合在一起，二者优势互补，同时将髙效厌氧与湿地或土地相结合，污染物去除率高，出水质好；其耗能低、产气量好，产生沼气作燃料，实现产能增效，减少污染。The utility model combines physics and biochemistry, and the advantages of the two complement each other. At the same time, the high-efficiency anaerobicity is combined with the wetland or the land. It can be used as fuel to increase production capacity and reduce pollution.

本实用新型，还可有其它多种实施方式，在不背离本实用新型精神及其实质的情况下，熟悉本领域的技术人员可根据本实用新型作出各种相应的改变和变形。The present utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the present utility model without departing from the spirit and essence of the present utility model.
