| titleOfInvention | A kind of method of wastewater treatment |
| abstract | The embodiment of the invention discloses a kind of method of wastewater treatment, for handling acrylic acid wastewater and acrylic ester wastewater, comprise the following steps：1) acrylic acid wastewater, is extracted with extractant, extraction phase and raffinate phase is obtained, distillation extraction phase or be that 20%~50%NaOH solution is stripped extraction phase to reclaim acetic acid with mass fraction；2), by step 1) in raffinate phase mixed with acrylic ester wastewater, obtain composite waste, adjust the pH value of composite waste to 10~14, flocculant is added thereto, carry out first time separating treatment, obtain the first separating liquid；3), to step 2) obtain separating liquid in add initiator, 0.5~3h of polymerisation at 50~100 DEG C, carry out second of separating treatment, obtain the second separating liquid.The method of the present invention, can process for producing acrylic acid and acrylate are produced simultaneously organic wastewater, operating cost is low, simple to operate. |
