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、木炭、沸石和各种土壤在MSL多土层系统中的作用。沸石LYR通过强化氨离子固定、硝化和反硝化作用，对脱氮起重要作用。然而，沸石作为氢氧化铁的载体在固磷方面并没有表现出优越的性能。土壤物种差异不大。长期处理较高浓度的垃圾表现出一定的土壤物种差异。在供试的三种土壤中，安迪生土、黑土表现最好，黄棕壤、红壤次之，沙质土、玛莎土表现最差。2、MSL系统具有应用于高浓度养猪场废水处理的潜力。最佳曝气量显著降低了BOD和P。但是，如果T-N浓度高于500ppm，则处理不稳定，效果较差。需将T-N稀释至100-200ppm以下。3、国内…长期现场处理更多的MSL废水已经成功地持续了8年。在曝气控制最优的情况下，MSL出水BOD<15ppm，T-N<15ppm，T-P<2ppm。建立了简单的曝气控制方法。24小时曝气时透明度、BOD、SS、T-N、NO_3-N、NH_4-N、T-P、pH和ORP的动态系统变化，透明度和pH可能是最简单的曝气管理指标。4、MSL系统成功应用于泰国曼谷Kasetsart大学食堂餐饮废水的处理。与该地区广泛使用的传统土壤入渗系统相比，MSL系统的处理性能有了很大的提高。5、通过对水稻土和菜园土的改良试验，发现MSL在长期生物处理废水过程中形成了IAP-沸石、铁磷铵沸石。较少
