摘 要

为微生物载体针对饮用水的深度处理问题，本课题通过对生物活性炭和生物陶粒技术的对比研究，尤其针对在低温和常温条件下，生物陶粒对滤后水中残留有机物的去除能力的研究。试验打破了以活性炭为深度处理单一填料的格局，采用了以陶粒作的深度处理技术。通过试验研究，达到了去除水中有机污染物、消毒副产物的前体物，提高饮用水水质的目的。
活性炭具有微孔丰富、比表面积大、吸附能力强等特点，是很好的水处理滤料，所以一直以来都用活性炭作为深度处理材料，但是活性炭具有造价昂贵，强度比较低，易破碎，反冲洗周期短等缺点。陶粒由于比表面积大、孔隙率高、挂膜效果好、价格低廉而日受青睐.试验还对生物陶粒和生物活性炭净水效能进行了比较，从对COD、氨氮、浊度的处理效果的比较，可以看出活性炭的去除率稍高于陶粒，但是差是很大别并不。从运行费用上进行比较，生物陶粒具有更大的优势。综合两方面的比较，陶粒完全可以在适当情况下取代活性炭成为生物载体作为深度处理滤料本章在净水效能上把活性炭与陶粒进行对比，并进行经济分析比较，综合两方面因素，确定选用陶粒代替活性炭进行深度处理的可行性[57]。

摘 要
Micro-organisms for the carrier for advanced treatment of drinking water problem, this issue through the BAC and bio-ceramic technology, comparative study, especially during low-temperature and room temperature conditions, the bio-ceramic filter for the water after the removal of organic residues in the capacity of research . Test broke the activated carbon to deal with the depth to fill a single pattern, so as to the use of ceramic for the advanced treatment technology. Experimental research through to the removal of organic pollutants in the water, disinfection by-products of the precursors to improve the quality of drinking water.

Microporous activated carbon with a rich, large surface area, such as strong absorption characteristics of a good water filter, it has been used as activated carbon to deal with the depth of material, but the cost of activated carbon with high intensity is relatively low and easy to break anti - Wash cycle and shorter shortcomings. As the ceramic surface area, porosity, biofilm effective and inexpensive and popular day. Test also bio-ceramic and biological activated carbon water purification performance are compared, from the COD, ammonia, turbidity deal with the effects of The comparison can be seen slightly higher than the removal of carbon-ceramic, but the difference is no other greatly. From the cost of running the comparison, the bio-ceramic with a greater advantage. Comprehensive comparison of the two, the ceramic can be replaced, where appropriate, be activated as a carrier of biological filter media to deal with the depth of water purification in this chapter on the effectiveness of the activated carbon and ceramic compared, and economic analysis, the Composite factors to determine Selection of ceramic in place of activated carbon to deal with in-depth feasibility [57].
