概要	Wastewater treatment design is the comprehensive planning and engineering of municipal and industrial treatment plants to remove contaminants (organic matter, nutrients, pathogens, trace organics) from domestic and industrial wastewater. Modern treatment plants integrate preliminary screening, primary settlement, secondary biological treatment (activated sludge, trickling filters, lagoons), advanced treatment (membrane filtration, oxidation, absorption), sludge processing, and biosolids management. The design balances regulatory compliance, treatment performance, energy consumption, land use, and capital and operational cost.	Constructed wetland design is an environmental engineering approach that harnesses natural biological and chemical processes—microorganism metabolism, plant uptake, soil sorption, sedimentation—to treat wastewater, stormwater, and agricultural runoff. Developed systematically in the 1970s by German researchers Seidel and Kickuth, constructed wetlands operate with minimal energy input and create amenity and biodiversity co-benefits alongside treatment. The design process integrates hydrology, biogeochemistry, and landscape planning to optimize contaminant removal.
