Laboratory sewage treatment equipment is based on the principle of multi-level ecological purification and nutrient cascade utilization. It integrates unit technologies such as hydrolysis and acidification, aquatic plant insulation and soilless cultivation, biological contact oxidation, plankton purification and constructed wetland technology, and is based on the ecological chain relationship. Sequentially, let the unit technologies of the five key links do their best, gradually degrade the pollutants in the wastewater into organic nutrients for heterotrophic microorganisms, and fully convert them into microorganisms, carbon dioxide and water in accordance with the relationship between the food chain, and finally achieve effective purification .

The effluent from the biological contact oxidation tank enters the sedimentation tank, and the suspended substances in the water are collected in the mud bucket area at the bottom of the tank under the action of physical sedimentation, and then are pumped by the sludge pump to the sludge drying tank to be dried, and then transported to the waste treatment station or through the waste treatment station. After the harmful chemical treatment, the effluent enters the ecological filter tank, and through the absorption and utilization of obligate microorganisms, the residual pollutants in the sewage are deeply reprocessed, and the NH 3 -N, P, SS, and color in the wastewater are further removed. The plankton is used to digest the sludge, and the amount of sludge produced is small, which solves the problems of siltation and trouble cleaning that are common in conventional constructed wetlands, and the system is not easy to be blocked.
