Experimental Study on Efficient Purification of Wastewater from a Quarry in Zhejiang
In order to solve the problem of large turbidity and fine particle size of suspended solids of quarry wastewater,efficient purification ex-periments were conducted on this wastewater with single organic flocculant,inorganic flocculant,regulator type and dosage,and optimizing agent com-bination.The results showed that under the combined reagents of regulator CaO 200 g/m3,inorganic flocculant PAC 2.5 g/m3,and organic flocculant PAM-new 12 g/m3,the wastewater turbidity was 97.30 NTU,which met the wastewater"zero discharge"production reuse requirements and industrial wastewater discharge standards.
