Abstract
The present invention relates to a combined wetland system for wastewater treatment and a wastewater treatment technique thereof. The combined wetland system for wastewater treatment is formed by connecting a biological regulation pond with an aerobic degradation and microbial cultivation pond through pipelines, wherein the aerobic degradation and microbial cultivation pond is connected with a diversion channel through an artificial undercurrent wetland unit which is connected with a direct interface of an artificial surface-current wetland unit. The biological regulation pond is provided with a wastewater inlet, and the artificial surface-current wetland unit is provided with a purified water outlet. The present invention has the wastewater treating technology that wastewater is firstly put into the biological regulation pond for carrying out precipitation, biological absorption and transformation and then is put into the aerobic degradation and microbial cultivation pond for carrying out an aeration reaction, and then the wastewater is adsorbed by media of artificial undercurrent wetland and plants and is finally sent into the artificial surface-current wetland. The wastewater is purified in the process of the utilization of aquatic animals and plants and natural precipitation. The combined wetland system for wastewater treatment and a wastewater treatment technique thereof can stably treat wastewater in high efficiency and high quality, and also have the advantages of small occupation area and low construction and operation cost; the present invention can be widely applied to point-source wastewater treatment for cities and towns, rivers, water reservoirs, lakes, tourism holiday resorts, etc.
