3B dye sulforhodamine Method of Wastewater Treatment

Should vote _JJ 【l volume 4.0mL. Then change the dosage of lime experiment, the data presented in Table 10. Lime dosage and COD, removal rate curve in Figure 5. Test data show that the wastewater back to adjust the pH value of water can achieve good control effect. From the above Figure 5, Table 10 shows 1O% FeS solution in volume suitable wastewater per 50mL adding 4.0mL, 10% milk of lime suitable inputs for the 18 ~ 20mL. 5 g lime dosage Chi stem / mL10% lime dosage and. . D. Removal rate curve table to determine lime dosage of 10 test data obtained 5OmL 1.6 mixture of sewage sedimentation test adding 10% FeSO, 4.0mL; 10% milk of lime 20mL, stir and then add a small amount of 0.1 % polyacrylamide solution, poured l00mL cylinder subsidence, recorded data are presented in Table ll, curve shown in Figure 6. Table l1 coagulation sludge settling test data sheet ll,[link widoczny dla zalogowanych], and Figure 6 shows that the overall sludge volume can be 1 / 3 dollars, the basis for engineering design. Test the water pH value of 1.7 out to adjust the water 50mL, pH value of 12.20, adding 1mo1L ~ HC1. Adjust pH 6.0 to 9.0. Record 1too1. LHC1 consumption. Results: Each. 50mL water 1lnol · LHCl14mL can be used to control pH value dropped to 8,0.2 stupid process 5045E40 Qiang 3530 deposition time of 6 ∞ / 0 Figure 6, the volume of sludge settlement and settlement process when the pilot asked the conclusions in accordance with the relationship,[link widoczny dla zalogowanych], arranging process process (see Figure 7) for engineering design ● capsule '1 'Lu,[link widoczny dla zalogowanych], ● ● 3 Deng and et al: Acid Red 313 Pi pick the method of treating wastewater of 1273 concluded outside a flow chart in Figure 7 with pink raw wastewater with high alkalinity water back to 2: l mixture, the initial startup or alkaline lye with the degree of dyeing wastewater by appropriate mixing ratio. 2 coagulation with FeSO solution,[link widoczny dla zalogowanych], milk of lime, followed by the addition of polyacrylamide, respectively, and pay attention to control of pH and mixing intensity, settling time should be greater than 3 1h appropriate. 4 in the drainage and waste acid can be discharged. Can achieve the following targets: CODc100 ~ 200mg · L a color <100 times, pH = 8 ~ 9.
