Deep treatment system of wastewater

The invention discloses a deep treatment system of wastewater, comprising: a tank arranged in a filler component; dirt-absorbing plants planted on the filler component; an inflow component arranged atthe upper end of the filler component; a collection pipeline arranged at the bottom of the tank and used to collect treated water. The filler component comprises: a filter filler layer allowing plantgrowth, a gravel contact oxidizing filler layer arranged below the filter filler layer, and a support and drainage filler layer arranged below the filter filler layer. The three treatment modes, dirt-absorbing plant absorption, filler filtering and bio-contact oxidization, supplement each other, overall filtering effect is improved, the treatment effect is far better that that under the nationalgrade I standard A, close to the standard for five types of water; operational energy consumption is low, and operation is automated and stable. 本发明公开了种深度处理污水系统，包括：池体，设置于池体内的填料组件，种植于填料组件上的吸污植物，设置于填料组件上端的进水组件，设置于池体底部并用于收集处理后的水的收
