项目摘要

1, The role of layrs of charcoal, zeolite, and various soils in MSL,Multi-Soil-Layring, system. Zeolite layr is important for nitrogen removal through enhancement of ammonium ion fixation, nitrification and denitrification. However, Zeolite did not show superior characteristics as a carrier of iron hydroxide for phosphate fixation. Difference of soil species was not dramatic. Long term treatment of relatively high concentration waste showed some difference of soil species. Andisols, Kuroboku soil, showed the best performaance, calyey Ultisols, Red soils, comes the next, sandy Entisols, Masa soil, showed the worst performance among the three soils tested.2, The MSL system showed the potential to apply high concentration piggery waste water treatment. Optimum aeration reduced the BOD and P dramatically. However, if T-N concentration is higher than 500 ppm, the treatment was not stable and poor. Dilution to T-N less than 100-200ppm was necessary.3, Long term on-site treatment of domestic … More waste water by MSL has been continued 8 years successfully. If aeration is controlled optimum, MSL showed the quality of treated water less than 15ppm of BOD,less than 15ppm of T-N and less than 2ppm of T-P.The simple way to control aeration was established. The on-off of 24hr aeration showed dynamic and systematic changes of Transparency, BOD,SS,T-N,NO3-N,NH4-N,T-P,pH,and ORP.The transparency and pH may be the best simple indicators for on-off aeration management.4, The MSL system was successfully applied to the treatment of restaurant and toilet waste water treatment at Kasetsart University cafeteria, Bangkok, Thailand. The MSL system showed dramatic improvement of treatment performance comparing traditional soil infiltration system widely used in the region.5, The, IAP-zeolite, iron ammonium phosphate zeolite was formed during the long term biogenic waste water treatment by MSL The IAP-zeolite showed function as an excellent soil conditioner throug the amendment trials to rice soils and vegetable soils.

1、MSL（Multi-Soil-Layring）系统中的木炭、沸石和各种土壤层的作用对于通过增强铵离子固定、硝化和反硝化作用来去除氮具有重要作用，但是沸石并没有表现出优越性。不同土壤种类对高浓度废物的长期处理表现出一定的相对差异。 Andisols、Kuroboku 土壤表现出最好的性能，calyey Ultisols、Red 土壤次之，沙质 Entisols、Masa 土壤在测试的三种土壤中表现出最差的性能。 2、MSL 系统显示出应用高的潜力。养猪废水处理。最佳曝气可显着降低 BOD 和 P，但如果 T-N 浓度高于 500 ppm，则处理不稳定且稀释效果较差。 T-N 低于 100-200ppm 是必要的。3、MSL 对生活废水的长期现场处理已成功持续 8 年，如果曝气控制在最佳状态，MSL 表明处理后的水质量低于 15ppm。 BOD，T-N小于15ppm，T-P小于2ppm。建立了简单的曝气控制方法，24小时曝气的开关显示出动态和系统性。透明度、BOD、SS、T-N、NO3-N、NH4-N、T-P、pH和ORP的变化。透明度和pH可能是开关曝气管理的最佳简单指标。4、MSL系统成功应用泰国曼谷农业大学食堂的餐厅和厕所废水处理与该地区广泛使用的传统土壤渗透系统相比，MSL 系统显示出处理性能的显着改善。5、 IAP-沸石，磷酸铁铵沸石是MSL在长期生物废水处理过程中形成的。通过对水稻土和菜土的改良试验，IAP-沸石显示出了优异的土壤改良剂功能。
