Embodiment Construction
[0013] The present invention will be further described in detail below with reference to the drawings and specific embodiments. However, it should not be understood that the scope of the above-mentioned subject matter of the invention is limited to the following embodiments.
[0014] Such as figure 1 As shown, the flue gas and dust generated by the combustion of boiler coal are collected and sent to the high-efficiency desulfurization and dust removal tower; at the same time, the production wastewater is precipitated after anaerobic and aerobic reaction, and the precipitated wastewater in the sedimentation tank is supplemented with clean water, and then in the water After adding the desulfurization and dust removal agent, it is sent to the desulfurization and dust removal tower to form water mist; the desulfurization agent in the water mist and the SO in the flue gas 2 When the acidic substance reacts to form a precipitate, at the same time, the water mist and the smoke are fully...

Abstract
The invention relates to a waste water and flue gas dust treatment process. The flue gas dust is collected in a high-efficiency desulfurization and dust removal tower; at the same time, a desulfurization and dust removal agent is added to the waste water that has undergone anaerobic and aerobic reactions to form water mist and sent to the desulfurization The dust removal tower is in full contact with the flue gas and dust. After the wastewater reacts in the high-efficiency desulfurization and dust removal tower, it enters the settlement ditch to settle, and the supernatant is settled in the artificial wetland before being discharged up to the standard; the flue gas treated in the high-efficiency desulfurization and dust removal tower is sent to the windshield to meet the standard discharge. By combining the waste water treatment line with the flue gas and dust treatment line and making comprehensive use of each other, multiple effects are achieved: using waste water to treat flue gas, saving desulfurizers for treating flue gas and saving treatment of flue gas Clean water for gas consumption. Use flue dust and flue gas to treat wastewater, reduce CODcr and SS of wastewater; save the cost of purchasing activated carbon decolorization adsorption beds for wastewater treatment by several million yuan.
Description
Technical field [0001] The invention relates to a process for treating waste water and flue gas and dust. Background technique [0002] At present, many chemical companies mostly adopt wastewater treatment processes: wastewater→anaerobic→aerobic→sedimentation→discharge. After the anaerobic-aerobic reaction, the wastewater has certain CODcr, color and suspended solids (SS), such as The alcohol production line used by the applicant has wastewater CODcr80-100mg / L, chroma 90-100 times, and SS80-100mg / L. Direct discharge of color and suspended solids through sedimentation is difficult to meet the national first-level emission standards. In order to meet the national first-level emission standards, activated carbon decolorizing adsorption beds or other facilities must be put in before the discharge, and only after treatment can it reach the national first-level emission standards. But its investment is very large, which makes wastewater treatment cost very high. [0003] At the same t...
