| Abstract: |
| The status of wastewater pollution prevention and control project in typical lead smelting enterprises is investigated through on-site investigation, discussion, questionnaires and expert consultation. The research results show that the construction cost of waste acid treatment facilities is about 8500~12270 yuan / T D, the running cost is about 21.5~36.8 yuan /t, the construction cost of acidic wastewater treatment facilities is about 5000~5800 yuan / T D, and the running cost is about 3.7~5.7 yuan /t. The cost of waste acid treatment in wastewater treatment of lead smelting enterprises is much larger than that of acidic wastewater. The construction cost is about 1.5~2 times of acid wastewater treatment, and the running cost is about 4~6 times of that of acid wastewater. The main reason is related to the concentration of acid and pollutant. |
