NOVELTY - Sewage water pre-processing method of artificial wetland comprises building a water planting tank with leakage-proof treatment; fixing plants in planting baskets by flexible material according to different planting densities; then fixing planting baskets on light material; and guiding sewage or wastewater after screening and settling process to flow into water planting tank, and then putting prepared plants into the tank, so that discharged water directly flows into or is directly pumped into artificial wetlands.    USE - Sewage water pre-processing method of artificial wetland.    ADVANTAGE - The method can quickly and efficiently remove large amount of suspended solid and half of organic matters in the sewage water, which may block the artificial wetlands. It can obviously improve the dissolved oxygen content in the sewage water flowing by water planting tank, improve the pollutant removing ratio of the wetlands, reduce the occupied area of artificial wetlands and reduce the investment for sewage water processing equipment and operation cost.    DETAILED DESCRIPTION - Sewage water pre-processing method of artificial wetland comprises:    (A) building a water planting tank with leakage-proof treatment, in which the tank is rectangular or square, is not greater than 0.1 m deep, and has a slope that is not less than 0.2%;    (B) controlling the feeding water force load to 0.01-0.5 m3/m2.day so as to define the length and width of the water planting tank to define the hydraulic retention time according to the field condition;    (C) washing off the soil on roots of aquatic or terrestrial plants in young period; according to types of plants, fixing plants in planting baskets by flexible material according to different planting densities; then fixing the planting baskets on light material; or directly fixing the plants on a light plate material floating on the surface of water; or directly planting in sewage water; and    (D) guiding the sewage or wastewater after screening and settling process to flow into the water planting tank; and then putting the prepared plants into the water planting tank, so that the discharged water of the water planting tank directly flows into or is directly pumped into artificial wetlands.
