Problems solved by technology
[0002] Wet desulfurization is often used in industrial production occasions, which can remove sulfur compounds in industrial waste gas, but at the same time, it will also produce a large amount of industrial wastewater, which needs further treatment before it can be discharged, otherwise it will cause environmental pollution, and untreated wastewater will flow into kills aquatic life in rivers
At present, there are many ways to treat wastewater, but the treatment efficiency is not high, and the effect of sulfur recovery and utilization cannot be achieved.

The present invention proposes a multi-stage treatment device for wet desulfurization wastewater. The treatment device is connected to one side of the desulfurization tower. The treatment device includes a plurality of reaction cylinders with open tops and a recovery cylinder in which the plurality of reaction cylinders are connected through conduits, and The filtering device and the first pump body are connected between adjacent reaction cylinders. A feed nozzle is provided on the top cover of the top port of the reaction cylinder, and the calcium compound can be added into the reaction cylinder through the feed nozzle. The filter device is connected to the water outlet, and the flocculent calcium sulfate produced in the reaction cylinder will stay in the reaction cylinder, and the free sulfate ions will enter the next reaction cylinder, so that adding calcium compounds many times can fully absorb the waste water. Sulfate ions are absorbed relatively thoroughly, and finally clear water that meets the discharge requirements can be obtained. The calcium sulfate remaining in the reaction cylinder is pumped into the recovery cylinder by the second pump body, and the calcium sulfate in multiple reaction cylinders can be recovered intensively.
Description
technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a multi-stage treatment device for wet desulfurization wastewater. Background technique [0002] Wet desulfurization is often used in industrial production occasions, which can remove sulfur compounds in industrial waste gas, but at the same time, it will also produce a large amount of industrial wastewater, which needs further treatment before it can be discharged, otherwise it will cause environmental pollution, and untreated wastewater will flow into Kills aquatic life in rivers. At present, there are many ways to treat wastewater, but the treatment efficiency is not high, and the effect of sulfur recovery and utilization cannot be achieved. In the process of wet desulfurization of industrial waste gas, quicklime is generally used to absorb sulfur in the waste gas. The waste water contains a large amount of calcium ions and sulfate ions. When we treat ...
