| 中文摘要 |
| 向污水处理厂的剩余污泥中投加相对于干污泥重量0.5%的SFC,在0.4bar的真空度下过滤,污泥的合水率由99.5%降至75%,污泥的体积降至原来的1/50,燃烧热值增大70倍,污泥比阻减少一倍多,而且泥饼的剥离性能好,滤液澄清度高. |
| 英文摘要 |
| 0.5% SFC with respect to the weight of dried sludge was added 10 excess sludge taken from a sewage plant. After filtering at a vacuum of 0.4 bar, the water ratio of the sludge was decreased from 99.5% to 75%; its volume reduced to 1/50; its colosific value increased to 70 times of the original value; its specific resistance reduced to 1/2 or less with a better stripping property; and, the clarity at filtrate was high. |
