Technical Field
The invention relates to the technical field of environmental protection, in particular to a flue gas dearsenification reactor and a flue gas dearsenification method.
Technical Field
With the increase of sewage discharge and the improvement of sewage treatment rate, the sludge output is increasing day by day, the sludge treatment is under great pressure, and the sludge incineration technology has the advantages of reduction, harmlessness, resource utilization and the like, so that the sludge incineration technology is widely popularized and used in recent years. However, the sludge contains arsenic in high concentration, which has a high toxicity and carcinogenicity, is discharged in the form of smoke gas when incinerated, and poses serious threats to the environment and human health.
The existing flue gas arsenic treatment technologies mainly comprise an adsorption method, an oxidation method and a treatment method by utilizing the existing air pollutant control device. Wherein, the adsorption method can be influenced by the combustion environment and the operation condition to cause the condition of instability or low, and the adsorbent is difficult to regenerate and becomes dangerous waste, the subsequent treatment cost is high and the secondary pollution is easy to cause. The oxidation method needs to consume a large amount of reagents, has high operation cost, and has difficult separation and recovery of arsenic in reaction products due to complex smoke components. The treatment effect and the stability of the existing air pollutant control device are influenced by actual working conditions such as the characteristics of the control device, the components of a burning substrate, the temperature of a hearth and the like, and the removal efficiency is unstable.
The biological method for treating the heavy metal is to remove the heavy metal by utilizing the flocculation, metabolism, enrichment, adsorption and other actions of microorganisms. The sulfate reducing bacteria can oxidize organic compounds by taking sulfate as a terminal electron acceptor, and hydrogen sulfide generated in the process can form metal sulfides with high chemical stability with heavy metals, so that the sulfate reducing bacteria can be widely researched in treatment of heavy metal industrial wastewater and treatment of heavy metal polluted soil. Meanwhile, the biological method has the advantages of small secondary pollution and low cost, and is widely applied to industrial waste gas purification, but is only limited to the treatment of nitrogen oxides, sulfur oxides and volatile organic compounds in the waste gas. The anti-sulfidation membrane bioreactor utilizes the characteristics of sulfate reducing bacteria and exerts the advantage of biological method for treating waste gas, has the advantages of simple process, low operation cost, high arsenic flue gas treatment efficiency and the like, and is an environment-friendly, economic and technically feasible purification means.
