【Abstract】 Compound flocuulant DDM-006 is developed for the alkali-washing wastewater in grease industry. It is cheap, convenient and effective. The best condition for treating the wastewater is defined by investigating the relationship between pH value, dose, temperature and COD-removal rate of wastewater. The best pH value is 3~5 and, when the pH value is 3, the COD- removal rate can come to 93.94%. The suitable dose of DDM-006 is 15～30mg/L, and in particular, at the point of 25mg/L, the COD-removal rate can reach 93.67%. The ideal temperature is 40℃～60℃ when the COD-removal rate is 92.98%.更多还原
