人工湿地相比于传统的活性污泥法处理污水,具有生态效益好,运行成本低,操作管理简单等优点。但人工湿地的使用寿命,被堵塞问题所制约,很大程度上限制了人工湿地的发展。 Compared with the traditional activated sludge method for sewage treatment, artificial wetland has the advantages of good ecological benefits, low operating costs, and simple operation and management. However, the service life of constructed wetlands is restricted by the problem of clogging, which largely limits the development of constructed wetlands.
人工湿地可分为表面流人工湿地,垂直潜流人工湿地和水平潜流人工湿地,其中处理效果较好的为垂直潜流人工湿地和水平潜流人工湿地,垂直潜流人工湿地脱氮效果好,但去除有机物的能力较弱,水平潜流人工湿地去除有机物的能力强,但脱氮效果较差。为增强处理效果,出现了多种复合人工湿地,垂直—水平潜流人工湿地为一种,但处理效果仍难达到出水要求,尤其是脱氮效果差。 Constructed wetlands can be divided into surface flow constructed wetlands, vertical subsurface flow constructed wetlands and horizontal subsurface flow constructed wetlands. Among them, vertical subsurface flow constructed wetlands and horizontal subsurface flow constructed wetlands have better treatment effects. Vertical subsurface flow constructed wetlands have good denitrification effect, but the removal of organic matter The capacity is weak, and the horizontal subsurface flow constructed wetland has a strong ability to remove organic matter, but the denitrification effect is poor. In order to enhance the treatment effect, a variety of composite constructed wetlands have emerged, and vertical-horizontal subsurface flow constructed wetlands are one type, but the treatment effect is still difficult to meet the water discharge requirements, especially the denitrification effect is poor.

There is a water inlet at each place for two-point water intake. The water in the connecting channel can provide carbon source for the denitrification in the horizontal subsurface flow constructed wetland, and the bottom of the vertical subsurface flow constructed wetland is equipped with an aeration tube, which can enhance the system's performance. Treatment capacity, especially the improvement of nitrification effect.
与现有技术相比,本发明的有益效果是:(1)垂直潜流人工湿地底部增加曝气装置,可提高硝化速率,并且可减缓湿地的堵塞;(2)采用两点进水的方式,将一部分原水由连接渠通到后段的水平潜流人工湿地中,为水平潜流人工湿地提供碳源,提高反硝化效果,同时减轻垂直潜流人工湿地的负荷;(3)两种湿地复合使用,可提高污染物的综合去除率。 Compared with the prior art, the beneficial effects of the present invention are: (1) Adding an aeration device at the bottom of the vertical subsurface flow artificial wetland can increase the nitrification rate and slow down the blockage of the wetland; A part of the raw water is connected to the horizontal subsurface flow constructed wetland in the rear section through the connecting canal to provide carbon sources for the horizontal subsurface flow constructed wetland, improve the denitrification effect, and reduce the load of the vertical subsurface flow constructed wetland; (3) The combined use of the two wetlands can Improve the comprehensive removal rate of pollutants.

具体实施方式 detailed description
下面结合附图对本实用新型专利进一步说明。处理污水时,进水阀门1和进水支管阀门3处于开启状态,一部分污水通过布水干管2进入布水支管14,经布水支管14均匀布水后进水垂直潜流人工湿地4,处理后经垂直潜流人工湿地出水孔6,进入连接渠8与另一部分经进水支管7进入连接渠8的污水混合后由水平潜流人工湿地进水孔9进入水平潜流人工湿地10,经过处理后由水平潜流人工湿地出水孔12进入出水渠11,最后经可调水位出水装置13排出湿地。 Below in conjunction with accompanying drawing, the utility model patent is further described. When treating sewage, the water inlet valve 1 and the water inlet branch valve 3 are in the open state, and a part of the sewage enters the water distribution branch pipe 14 through the water distribution main pipe 2, and after the water is evenly distributed through the water distribution branch pipe 14, the water enters the vertical underflow constructed wetland 4, and after treatment After passing through the outlet hole 6 of the vertical subsurface constructed wetland, it enters the connecting channel 8 and mixes with another part of the sewage that enters the connecting channel 8 through the water inlet branch pipe 7. The outlet hole 12 of the subsurface constructed wetland enters the outlet channel 11, and finally discharges the wetland through the adjustable water level outlet device 13.
垂直潜流人工湿地4设有曝气装置,空气经曝气干管5进入曝气支管15,经曝气支管15的均匀布气后,进入垂直潜流人工湿地4,来提高微生物活性和溶解氧浓度,从而提高处理效果,尤其是增强硝化效果。而一部分污水不经垂直潜流人工湿地4处理而进入连接渠8与垂直潜流人工湿地4的出水混合后进入水平潜流人工湿地10,为水平潜流人工湿地10内的反硝化提供充足的碳源。当出水中氨氮含量高时,通过增大曝气来提高处理效果;当水平潜流人工湿地10出水中硝酸盐含量高时,通过调大进水支管阀门3来增加进入连接渠8的污水量以提高处理效果。 The vertical subsurface flow artificial wetland 4 is equipped with an aeration device, and the air enters the aeration branch pipe 15 through the aeration main pipe 5, and after being uniformly distributed by the aeration branch pipe 15, it enters the vertical subsurface flow artificial wetland 4 to improve microbial activity and dissolved oxygen concentration , so as to improve the treatment effect, especially to enhance the nitrification effect. And part of the sewage is not treated by the vertical subsurface flow constructed wetland 4 and enters the connecting channel 8 to mix with the effluent of the vertical subsurface flow constructed wetland 4 and then enters the horizontal subsurface flow constructed wetland 10 to provide sufficient carbon source for denitrification in the horizontal subsurface flow constructed wetland 10 . When the ammonia nitrogen content in the effluent water is high, the treatment effect is improved by increasing the aeration; when the nitrate content in the effluent water of the horizontal subsurface flow artificial wetland 10 is high, the amount of sewage entering the connecting channel 8 is increased by adjusting the valve 3 of the water inlet branch to increase Improve processing effect.
