| titleOfInvention | A treatment process for tunnel construction wastewater |
| abstract | The invention relates to the technical field of water pollution control. The purpose is to provide a tunnel construction wastewater treatment process that can effectively improve the efficiency of wastewater treatment. The technical solution adopted in the present invention is: a tunnel construction wastewater treatment process, including the following steps: A. First-level natural settlement treatment: the wastewater is passed into the grit chamber, and the wastewater is preliminarily removed through natural precipitation during the flow process. Large particle impurities in wastewater; B. Pre-flocculation and post-coagulation aid treatment: the wastewater that has undergone primary natural settlement treatment is pumped into the flocculation settler by the first pump, and flocculant is first added to the wastewater to form preliminary flocculation After solidification, add a coagulant to the wastewater to form larger flocs with nets and bridges, which are easier to settle; C, secondary natural settlement treatment; D, sludge concentration treatment; E, sludge dehydration treatment. The invention can greatly improve the treatment speed and treatment effect of tunnel construction wastewater. |
