摘要：

Distillery industries are responsible for the generation of ecotoxic wastewater called spent wash. They discharge their untreated wastes directly into the natural environments which cause various adverse effects on soil, water, air and health. It contains caramel, melanoidin and much more toxic chemicals. Melanoidin is a recalcitrant pigment responsible to give brownish colour to spent wash. The level of Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) are key indicators of wastewater characteristics and treatment. In the current investigation, we introduced a new biocarbon is generated using a novel medicinal plant Garland daisy (Glebionis coronia – Asteraceae). The removal capacity of the biocarbon is significantly enhanced by interfacing with inert silica as support material. The dirt free distillery wastewater was introduced into the batch reactor system and biosorption process is carried out at room temperature of 30 ±2°C.The results indicated that, 98.5% of organic load is removed with biocarbon dose rate of 2.5g/100 mL at 180 min equilibrium time. The higher growth of fodder grass and leafy vegetables such as Coriandrum sativum L. and Amaranthus caudatus in a pilot project are observed.
