Problems solved by technology

At present, its application is becoming more and more widespread, but the clogging problem of constructed wetlands is becoming more and more an obstacle to its application. Clogging is a common natural effect in all high-load and high-ammonia-nitrogen wastewater filtration systems. It is manifested in two aspects: first, clogging The layer is a good biological filter, which can improve the treatment efficiency of wetlands. Moderate mechanism pore clogging can expand the unsaturated flow area inside the wetland treatment system and improve the treatment effect; secondly, clogging will make the hydraulic performance of wetlands worse, Thus affecting the water flow path, and ultimately affecting the treatment effect and operating life of the wetland

Abstract

The invention relates to a three-stage treatment device and method of high-ammonia / nitrogen wastewater in an alternate-flow artificial wetland. The three-stage treatment device comprises a nanometer aeration ablation device, wherein a nanometer aeration disc connected with a nanometer aeration machine is arranged inside the nanometer aeration ablation device and located above a sludge outlet; the alternate-flow artificial wetland is connected to a surface-layer turbulence screen filter by virtue of a water outlet pipe; a water outlet of a water storage tank of the surface-layer turbulence screen filter is connected with a cyclone desanding device by virtue of a hydraulic pump; a sludge outlet is formed in the bottom of the cyclone desanding device, a stirrer is arranged at the top of the cyclone desanding device, impellers and paddles of the stirrer incline upwards and the upper part of the cyclone desanding device is connected with a backwash pump. The invention also discloses a three-stage deep treatment method of high-ammonia / nitrogen wastewater effluent by virtue of the combined device.

Description

technical field [0001] The invention relates to a combined device for treating high-ammonia-nitrogen wastewater in three stages by alternating flow artificial wetlands. [0002] The present invention also relates to a method for advanced treatment of high-ammonia-nitrogen wastewater with three-stage effluent by utilizing the above-mentioned combined device. Background technique [0003] Constructed wetlands refer to man-made, controllable and engineered wetland systems, which are designed and constructed to treat high-ammonia wastewater by optimizing the combination of physical, chemical, and biological actions in the wetland ecosystem. At present, its application is more and more extensive, but the clogging problem of constructed wetlands has become an obstacle to its application. Clogging is a common natural effect in all high-load and high-ammonia wastewater filtration systems. It is manifested in two aspects: first, clogging The layer is a good biological filter, which ...
