摘要

Electrocoagulation was investigated for the treatment of agro-industry wastewaters,namely,meat processing,cereal products,food beverages and abattoir.Initial studies were carried out to check the performance of each of the agro-industry wastewaters(in terms of COD removal).The total cost(including,electrical power consumed,chemicals and consumption of electrodes)of the treatment varied between 0.95 and 4.93 m~(-3).Abattoir wastewater resulted in higher COD removal of 85-86%.Subsequent studies were performed in details on the selected abattoir wastewater.Bipolar mild steel electrode gave higher soluble COD removal(82%).Likewise,percent soluble COD removal as a function of pH and conductivity confirmed no need of acidification and electrolyte addition.The coupling of electrocoagulation with flocculation process resulted in effective removal of organics(82% total COD removal),inorganics(with the exception of nitrogen),pathogen destruction and solids and turbidity removal.Thus,electrocoagulation-flocculation process can be envisaged as an effective treatment process for decontamination of agro-industry wastewaters.
