An automatic sewage treatment system based on constructed wetland and its control method

Abstract

The invention discloses an automatic sewage treatment system based on a constructed wetland. The system comprises wetland plants, a drawer type sealed wetland box where various filtering matrixes are laid therein, a water inlet pipe, a water seepage pipe, a water storage cavity, a water outlet pipe, a controller, a detector and an electronic display screen. The water inlet pipe and the water seepage pipe are sequentially communicated with the water storage cavity, the wetland box and the water outlet pipe. The water storage cavity is communicated with the wetland box. Flow guide holes are formed in a flow guide plate. The electronic display screen is installed on the ground, and the controller and the detector are arranged in the electronic display screen and connected with the wetland box through signals. According to the automatic sewage treatment system based on the constructed wetland and a control method of the system, control and detection units and the like are adopted, and intelligence of the sewage treatment system is enhanced. Meanwhile, the nitrogen and phosphorus removal efficiency of the constructed wetland sewage treatment technology is improved, the problem that a traditional constructed wetland treatment technology cannot eliminate heavy metal pollution easily is solved, and workloads for later maintenance of the sewage treatment system are reduced.

Description

technical field [0001] The invention relates to the technical field of artificial wetland sewage purification and treatment systems, in particular to an automatic sewage treatment system based on artificial wetlands and a control method thereof. Background technique [0002] Constructed wetland is a ground similar to swampland that is artificially constructed and operated under control. Sewage and sludge are distributed to the artificially constructed wetland in a controlled manner. When sewage and sludge flow in a certain direction, they are mainly used It is a technology for treating sewage and sludge through the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. Its mechanism of action includes adsorption, retention, filtration, redox, precipitation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration of water and nutrient absorption, and the action of various animals. Constructe...
