Unpowered underflow ecological sewage interception ditch system and construction method thereof
The invention relates to an unpowered underflow ecological sewage interception ditch system. The system comprises a ditch main body, and a filling bottom material supporting layer, a double-medium biological matrix layer and an ecological planting layer which are laid in the ditch main body, and submerged plants and emergent aquatic plants are planted on the ecological planting layer. The construction method comprises the following steps: constructing the ditch main body with an inverted trapezoidal structure; laying an impermeable layer on the bottom of the ditch main body and the side slope; paving concrete and mortar pebbles to obtain a filling backing material supporting layer; mixing natural zeolite, porous ecological bricks, a curing agent, phosphate and a microbial mixed powdery fungicide, and paving the mixture on the filling backing material supporting layer to obtain a double-medium biological matrix layer; laying an ecological planting layer on the double-medium biological matrix layer; planting emergent aquatic plants and submerged plants on the ecological planting layer. An appropriate biological inhabiting environment is established, and a good micro-ecological succession structure of pollutants, microorganisms, planktons and submerged/emergent aquatic plants is formed, so that the control on non-point source pollutants such as nitrogen and phosphorus in the rural planting industry is enhanced.
本发明涉及无动力潜流生态截污沟渠系统，包括沟渠主体以及铺设于沟渠主体内的填充底料支撑层、双介质生物基质层和生态种植层，生态种植层上种植沉水植物和挺水植物。施工方法：施工倒梯形结构的沟渠主体；沟渠主体底部与边坡上铺设防渗层；铺盖混凝土和浆砌卵石，得到填充底料支撑层；将天然沸石、多孔生态砖、固化剂、磷酸盐和微生物混合粉状菌剂混合配置，铺设于填充底料支撑层上，得到双介质生物基质层；在双介质生物基质层上铺设生态种植层；生态种植层上种植挺水植物和沉水植物。建立适宜的生物栖息环境，形成“污染物‑微生物‑浮游生物‑沉水/挺水植物的良性微生态演替结构，从而强化对农村种植业氮磷等面源污染物的控制。
