环保酵素对室内空气污染物和湖水生化成分含量的影响

Effects of Environment-friendly Ferments on Indoor Air Pollutants and Biochemical Components in Lake Water

为科学验证环保酵素对空气和污水的实际净化效果,采用国家标准方法,分析了喷洒环保酵素后室内空气污染物的含量变化以及添加环保酵素后湖水中叶绿素a(藻类)、氨氮、总磷的含量变化。结果表明:室内喷洒一定浓度一定量的环保酵素,对空气中甲醛含量没有显著影响,但能极显著降低苯、甲苯、二甲苯的含量,使其含量降低至无(P<0.01);对总挥发性有机物含量在一定时间内能发挥作用,使其含量降低至无,但一定时间后,其含量又会上升。环保酵素能极显著降低湖水中叶绿素a(藻类)、氨氮和总磷的含量(P<0.01);10%环保酵素对叶绿素a的处理效果最好;2%环保酵素对氨氮、总磷的处理效果最好。环保酵素的发酵原材料不同,对水体的处理效果也存在一定的差异。

In order to scientifically verify the actual effect of environment-friendly ferments on air purification and sewage treatment,this paper has determined the changes of indoor air pollutants after spraying environment-friendly ferments,and the contents of chlorophyll a,ammonia nitrogen and total phosphorus in the lake water added with environment-friendly ferments by the national standard method.The results showed that indoor spraying a certain amount of environment-friendly ferments at a certain concentration had no significant effect on the content of formaldehyde in the air,but could extremely significantly reduce the contents of benzene,toluene and xylene to zero(P<0.01);it could make the content of total volatile organic compounds reduced to zero over a certain period,then the content would rise again.On the other hand,environment-friendly ferments could extremely significantly reduce the contents of chlorophyll a in algae,ammonia nitrogen and total phosphorus in lake water(P<0.01);10%environment-friendly ferments have the best treatment effect on chlorophyll a;2%environment-friendly ferments have the best treatment effect on ammonia nitrogen and total phosphorus.There are some differences in treatment effects for water body due to different raw materials used in fermentation for environment-friendly ferments.
