摘 要
近年来，随着国民经济突飞猛进的发展，居民生活质量也不断改善，尤其是
在居住方面，大量装修原料、家具以及家电设备持续涌入室内，造成了严重的室
内环境污染。同时，室外环境中工业废气、汽车尾气以及燃料燃烧产物的大量排
放，使得室外雾霾天气日益严重，致使室外新风不“新”，在这种情况下，即使对
室内增加新风量，室内空气品质也难以得到改善，反而进一步恶化了室内环境污
染，严重威胁着人体健康。为改善室内空气质量，出现了多种室内空气净化技术，
本课题通过综合比较分析现有的室内空气净化技术，提出了一种结合混合媒体的
加湿与电离室内空气净化技术。
本课题首先分别对单一的混合媒体中的 KOH 改性活性炭、活性高锰酸钾球
以及加湿和电离技术的基本净化机理及其对 SO2和甲醛的去除机理进行了理论
分析；然后在此基础上将混合媒体、加湿、电离相结合，设计了去除气体污染物
的整体净化方案，并对该组合技术的的特点与优势、以及其对 SO2和甲醛的协同
净化机理进行了分析；再次为了验证这三种技术的结合后的优势及其产生的 O3
浓度是否在国家标准控制范围内，在风道式空气净化性能测试台上测试了不同组
合方式下的过滤器对 SO2和甲醛的一次净化效率以及电离过滤器产生的 O3浓度；
最后为了研究该组合技术在空气净化器中的应用性，设计了一台应用该净化技术
的空气净化器样机，并依据《空气净化器》（GB/T 18801-2008）中的测试方法，
在30m³环境实验舱内测试了该样机对颗粒物 PM2.5 和甲醛的去除效果。
由风道式空气净化性能测试台中不同实验工况下测得的数据可知，在相同的
实验条件下，当释放的上游 SO2气体浓度在 0.6 mg/m³~3.0mg/m³时，混合媒体过
滤器相比于比单独的 KOH 改性活性炭过滤器，对 SO2的一次净化效率提高了
16.8%~17.4%；加湿过滤器与混合媒体共同作用后，对 SO2的一次净化效率在混
合媒体的基础上提高了 22.7%~25.8%；最后电离过滤器的加入，使得 SO2的一次
净化效率又提高了2.1%~3.9%。同样，当释放的甲醛气体的上游浓度在 0.2
mg/m³~1.0mg/m³时，混合媒体相比于单独的 KOH 改性活性炭，对甲醛的一次净
化效率提高了 9.2%~10.4%；加湿与混合媒体共同作用后，比单独的混合媒体对
甲醛的一次净化效率提高了 11.9%~13.7%；最后电离过滤器的加入，使得甲醛的
一次净化效率又提高了 2.4%~3.0%。由此可见，混合媒体相比于单独的 KOH 改
性活性炭有利于提高对 SO2/甲醛的一次净化效率，且加湿与电离的加入进一步
提高了混合媒体对 SO2/甲醛的一次净化效率。同时，测得电离过滤器产生的 O3
浓度为 0.027ppm，小于国家标准允许的 0.047ppm，在国家标准控制范围内，表
明该技术是安全的。由环境实验舱内空气净化器样机对 PM2.5/甲醛净化性能的测
试结果可知，净化器样机在 20min 内对 PM2.5 的去除率为 99.4%，洁净空气量为
457.7m³/h；在 52min 内对甲醛的去除率为 63.7%，洁净空气量为 35.1m³/h。与市
场上产品相比净化性能较高，具有很好的应用前景。
由上述比较分析可知，结合混合媒体的加湿与电离室内空气净化技术具有较
好的净化性能，且使用安全，在空气净化器样机中也具有良好的应用效果。相关
实验数据与研究成果为今后相关净化产品的研发与实际应用提供了一定的参考
与借鉴。

ABSTRACT
In recent years, with the rapid development of our national economy, people’s
living standard has been improved greatly, especially in the indoor living conditions, a
large number of decoration materials, furniture, and household appliance are brought
indoor, causing serious indoor pollution. In addition, a lot of emissions of industrial
waste gas, vehicle exhaust and fuel combustion products have made the outdoor haze
weather becoming more serious, causing outside air no fresh. In this case, even if we
do ventilation, it is hard to improve the indoor air quality. On the contrary, it causes
the indoor air quality even worsen and more harmful to human health. To improve the
indoor air quality, a variety of indoor air purification technologies have emerged. By
comparing and analysising the various kinds of purification technologies, this paper
proposes an indoor air purification technology of mixed media combined with
humidification and ionization.
Firstly, the basic purification mechanism of mixed media（KOH modified carbon
and activated potassium permanganate ball）,humidification and ionization technology
were analyzed respectively, including the purification mechanism purifying SO2 and
formaldehyde. Then, the characteristics and advantages and the mechanism of the
combined purification technology with mechanism of mixed media and
humidification and ionization were introduced, including the purification mechanism
of purifying SO2 and formaldehyde by the combined purification technology.
Furthermore, based on the introduction, the purification scheme of removing gas
pollution and the concrete implementation ways were presented. After that, in order to
validate the advantages of the combined purification method and the O3 concentration
produced by the ionization filter under the national standard control range, the
instantaneous purification efficiency on SO2 and formaldehyde with different kinds of
combinations and the O3 concentration produced by the ionization filter were tested
on the air duct test system. Finally, in order to study the applicability of the combined
purification technology on air cleaner, the paper designed and accomplished an air
cleaner applied with the combined purification technology, and tested its purification
performance on PM2.5 and formaldehyde in a 30m3 environmental chamber according
to the method specified in the《air cleaner》（ GB/T 18801-2008 ）.
According to the test data under different experimental designs on the air duct
test system ,at the same experimental conditions, when the upstream concentration of
SO2 was during 0.6mg/m3~3.0 mg/m3, the instantaneous purification efficiency of the
air filter filled with mixed media was 16.8%~17.4% higher than the air filter filled
with just KOH modified active carbon; and when the mixed media filter combined
with the humidifying filter, the instantaneous purification efficiency of the air filter
filled with mixed media was improved by 22.7%~25.8%; when the ionization filter
was working with the mixed media filter and the humidifying filter, the instantaneous
purification efficiency of the mixed media filter combined with the humidifying filter
was improved by 2.1%~3.9%. When the upstream concentration of formaldehyde was
during 0.2 mg/m3~1.0 mg/m3, the instantaneous purification efficiency of the air filter
filled with mixed media was 9.2%~10.4% higher than the air filter filled with just
KOH modified active carbon; and when the mixed media filter combined with the
humidifying filter, the instantaneous purification efficiency of the air filter filled with
mixed media was improved by 11.9%~13.7%; when the ionization filter was working
with the mixed media filter and the humidifying filter, the instantaneous purification
efficiency of the mixed media filter combined with the humidifying filter was
improved by 2.4%~3.0%. The results showed that to the instantaneous purification
efficiency for SO2 and formaldehyde, the mixed media was more beneficial than the
single KOH modified active carbon, and the mixed media combined with humidifying
was more beneficial than the single mixed media, and the mixed media combined
with humidifying and ionization more beneficial than the mixed media combined with
humidifying. At the same time, the tested O3 concentration produced by the ionization
filter was 0.027ppm, lower than the 0.047 ppm that allowed by the national standard,
which is in the scope of the national standard control.
The test results of the air cleaner which applied with the technology of the mixed
media combined with humidification and ionization technology in a 30m3
environmental chamber showed that, the removal rate of the air cleaner on PM2.5 was
99.4% in 20 minutes, and the clean air delivery rate was 457.7m³/h. On the other hand,
the removal rate of the air cleaner on formaldehyde was 63.7% in 52 minutes, and the
clean air delivery rate was 35.1m³/h. This result is higher than the most of air cleaner
products on the market, having a broad application prospect.
All in all, the technology of mixed media combined with humidification and
ionization is a kind of indoor air purification technology which owns good
purification performance and has a good application effect in the air cleaner.
Meanwhile, the research results provide an improved technology on purifying indoor
air pollution, and the related experimental data and research results can provide some
reference on the development and practical application of the future purification
products.
