More Information
Summary:The invention discloses a terrace type landfill leachate treatment system. The terrace type landfill leachate treatment system comprises a water collecting pond, a coagulative precipitation tank, an advanced oxidation pond, a transparent greenhouse biochemical pond and a biochemical pond which are sequentially arranged, wherein the coagulative precipitation tank, the advanced oxidation pond and the transparent greenhouse biochemical pond are arranged in a terrace type structure from top to bottom. The terrace type landfill leachate treatment system is high in environmental adaptability and good in sewage treatment effects, and by means of physical and chemical coagulation, advanced oxidation and transparent greenhouse biochemical treatment, achieves an effluent COD (chemical oxygen demand)removal rate up to 90%, an ammonia nitrogen removal rate up to 95% and a suspended solid removal rate up to 98%, and produced sludge is applicable to resource reclamation. By taking terrain gravity difference as the driving
