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，沸石和各种土壤的作用在MSL，多土壤层，系统中。通过增强铵离子固定，硝化和否定性，沸石层对于去除氮的去除至关重要。然而，沸石并未显示出作为用于磷酸盐固定的铁氧化铁载体的优越特征。土壤物种的差异不是戏剧性的。长期治疗相对较高的浓度废物显示出一些土壤物种的差异。 Andizoku土壤，Kuroboku土壤表现出最佳性能，Calyey Ultisols，红色的土壤，接下来是Sandy Entisols，Masa土壤，在经过测试的三种土壤中表现出最差的性能。2，MSL系统显示出施加高浓度的高浓度猪手术的潜力。最佳曝气大大降低了BOD和P。但是，如果T-N浓度高于500 ppm，则治疗不稳定且差。对T-N的稀释小于100-200ppm。3，长期对国内的现场治疗……MSL的更多废水成功持续了8年。如果充气受控最佳，则MSL显示出小于15ppm BOD的处理水的质量，小于15ppm的T-N和小于2ppm的T-P。建立了控制曝气的简单方法。 24小时曝气的开关显示透明度的动态和系统变化，BOD，SS，T-N，NO3-N，NH4-N，NH4-N，T-P，pH，pH和ORP。透明度和pH值可能是On-Off Aeration Management的最佳简单指标。4，MSL系统成功地应用于Kasetsart Cafok，Thkkok，Thkkok，Thkk，bangk，bangk，bang，bang，成功地应用于餐厅和洗手间水的处理。 MSL系统显示了比较该地区广泛使用的传统土壤浸润系统的治疗性能的显着改善。5，IAP-沸石，磷酸铵铁沸石在MSL长期生物废水处理过程中形成了IAP-Zeolite在IAP-Zeolite的长期生物废水处理过程中，通过Amendment to Amentment to rocess of Rice Sobles和蔬菜，IAP-Zeolite在土壤中表现出了极好的土壤调节物。较少的
