Application number 201610093882. X Application date 2016. 02. 19 Applicant Xiamen Kelinda Environmental Technology Co., Ltd. Address 361000 No. 20, Neizhongli, Neilin Village, Xinglin Street, Jimei District, Xiamen City, Fujian Province Inventor Huang Hui Zhang Name of invention A treatment process for electroplating comprehensive wastewater Summary The present invention belongs to the field of wastewater treatment, and specifically relates to a treatment process for electroplating comprehensive wastewater. The specific steps of the process are: (1) Primary reaction: the electroplating comprehensive wastewater is sequentially broken, coagulated, and adjusted to pH 10. 5〜11. 5. After flocculation, precipitation treatment, solid-liquid separation, the supernatant (2) Secondary reaction: The primary effluent is broken down, coagulated, and adjusted to pH 10. 5〜11. 5. Adsorption enhancement reaction, polyacrylamide flocculation, precipitation treatment, After solid-liquid separation, adjust the pH value of the supernatant to 6~9 to meet the discharge standard. After the electroplating comprehensive wastewater is treated by this process, the content of heavy metals and COD in the discharged water is much lower than the water quality after the traditional process, and reaches the limit standard in Table 3 of GB21900-2008 "Electroplating Pollutant Discharge Standard". |
