摘　　要：为了解基于不同净化原理的室内环境空气甲醛净化方法的净化性能以及协同净化的效果,选取常用的净化原理代表性产品(活性炭、光触媒净化产品、生物酶甲醛清除液)作为研究对象,基于环境舱进行了甲醛净化性能测试。结果表明:(1)活性炭的原料特性影响其甲醛净化能力,净化效果表现为椰壳活性炭>果壳活性炭>竹木活性炭;日常所用光源的不同对光触媒净化产品的甲醛净化效果影响不大;生物酶甲醛清除液的净化效果取决于其稀释比例。(2)3种净化方法中基于物理吸附法的活性炭的甲醛净化性能最优,基于光催化氧化法的光触媒净化产品次之,之后是基于生物酶降解法的生物酶甲醛清除液。(3)净化产品的联用均提高了甲醛去除率,但提高程度有限。活性炭分别与光触媒、生物酶联用时表现出比光触媒与生物酶联用更高的甲醛去除率。研究结果对设计和开发具有高效甲醛净化能力的新型复合材料具有一定参考价值。In order to understand the formaldehyde purification performance and the effect of collaborative purification of formaldehyde purification products based on different purification principles in indoor ambient air,typical products(activated carbon,photocatalyst purification product,biological enzyme formaldehyde removal solution)were selected as research objects,and formaldehyde purification performance tests were carried out in the environmental chamber.The results showed that:(1)the raw material characteristics of activated carbon affected its formaldehyde purification ability,and the purification effect was shown as coconut shell activated carbon>fruit shell activated carbon>bamboo and wood activated carbon.The difference of the light source used in daily life had little effect on the formaldehyde purification effect of photocatalyst purification product.The purification effect of the biological enzyme formaldehyde removal solution depended on its dilution ratio.(2)Among the three purification methods,the formaldehyde purification performance of activated carbon based on physical adsorption method was the best,followed by photocatalyst purification product based on photocatalytic method,and the biological enzyme purification product based on biological enzyme degradation method showed the worst formaldehyde purification performance.(3)The synergistic use of purification products improved the formaldehyde removal effect,but the improvement rate was limited.When activated carbon was used in combination with photocatalyst and biological enzyme,it showed a higher formaldehyde removal rate than joint use of photocatalyst and biological enzyme.This study had reference value for the design and development of new composites with efficient formaldehyde purification ability.
