光催化治理技术在城市绿色生态住宅项目的应用

On application of photocatalytic treatment in urban green residences

随着城市生态文明建设和居民对居住环境要求的不断提高,“绿色生态小区”建设成为现代城市住宅规划和建设的趋势。“绿色生态小区”中,有机污染物(化肥、农药、抗生素、腐殖质等)、致病菌、病毒等成分复杂并且难以生化降解,对水安全造成极大影响,而室内外的NO_(x),SO_(x),VOCs,CH_(2)O等有毒气体治理是公认的环境治理难题。光催化氧化技术能够对这些毒害作用物质进行有效降解,且操作条件简单、使用成本较低,非常适合城市绿色生态小区环境修复治理。主要介绍了光催化技术在城市水体和气体典型污染物治理领域的研究进展及其在城市绿色生态小区项目建设中的应用前景。

Along with urban ecological civilization and the increasing demands for the living environment of residents, the paper indicates the construction of green residential complexes turns to be the tendency of the modern urban residence planning and construction, illustrates the organic pollutants including fertilizers, pesticides, antibiotics, and humus, pathogenic bacterium and virus are hard to be biochemically degraded due to their complicated components, which will impact the water safety, while indoor and outdoor poisonous gases including NO_(x),SO_(x),VOCs,CH_(2)O are commonly regarded as the problems for the environmental treatment, clarifies photocatalytic treatment can effectively degrade the poisonous chemicals with its easy operation, lower cost, so it can be popularly adopted in the treatment of the green residential complexes in cities, and mainly introduces the research development of the technique in the urban water bodies and gas pollutants treatment and its application prospect for the green residential complexes in cities.
