【摘要】：工业企业生成的大量废气、废水对我国环境造成了严重污染,缓解方式为采用高效空气净化装置和污水处理装置。该文针对低温等离子体易产生副产物氮氧化物和臭氧,光催化对可见光响应弱、光量子利用效率低的缺点,设计了一种高效能的空气净化装置,以达到减少副产物排放,提高净化能效的目的。通过实验研究了单独低温等离子体、单独光催化及2种技术协同情况下对污染物甲醛去除效果的影响,并对比了三者作用时的降解率。实验结果表明,风管为九宫格形与风管为普通方形相比,有利于提高光催化去除甲醛的效率;2种技术协同后可有效提高污染物甲醛的去除效果,同时减少氮氧化物的排放,提高净化能效,并可将臭氧变废为宝用以工业废水处理。
[Abstract]:A large amount of waste gas and waste water produced by industrial enterprises have caused serious pollution to the environment of our country. The methods of mitigation are high efficiency air purification device and sewage treatment device. In this paper, nitrogen oxide and ozone, the by-products of low temperature plasma, are easy to be produced. Due to the weak response of photocatalysis to visible light and the low efficiency of quantum utilization of light, a highly efficient air purifying device is designed to reduce by-product emissions and improve the efficiency of purification. The effect of photocatalysis alone and two technologies on the removal of formaldehyde was studied. The results showed that the air duct was H5 home page and the air duct was square. It is beneficial to improve the efficiency of photocatalytic removal of formaldehyde and can effectively improve the removal efficiency of pollutant formaldehyde, reduce the emission of nitrogen oxides, improve the efficiency of purification, and turn ozone into a treasure for industrial wastewater treatment.
