有机-无机复掺絮凝剂对渣土废泥浆脱水效果影响
|
摘要
针对地铁盾构出来的大量渣土废泥浆污染环境,不便施工的现状,本文将渣土废泥浆作为研究对象,通过上清液浊度、絮体含水率以及絮体大小等指标研究有机-无机复掺絮凝剂对渣土废泥浆絮凝效果影响。研究结果表明:(1)含水率为99%的渣土废泥浆,复掺PAC和APAM、PAC和CPAM的最佳掺量分别是0.02%+2.0×10~(-4)%、0.02%+5.0×10~(-4)%;(2)含水率为98%的渣土废泥浆,复掺PAC和APAM、PAC和CPAM的最佳掺量分别是0.06%+7.0×10~(-4)%、0.06%+9.0×10~(-4)%;(3)含水率为97%的渣土废泥浆,复掺PAC和APAM、PAC和CPAM的最佳掺量分别是0.12%+7.0×10~(-4)%、0.12%+1.4×10-3%。
At present,the mud disposal from subway pollutes the environment seriously and has negative effect on construction. The mud disposal will be regarded as the research object in this test. The flocculation effects of organic-inorganic composite flocculant on the mud disposal are researched. The results show that:( 1) When the water content is 99%,the optimal dosage of PAC and APAM is 0. 02%and 2. 0 × 10~(-4)%,the optimal dosage of PAC and CPAM is 0. 02% and 5. 0 × 10~(-4)%;( 2) When the water content is 98%,the optimal dosage of PAC and APAM is 0. 06% and 7. 0 × 10~(-4)%,the optimal dosage of PAC and CPAM is 0. 06% and 9. 0 × 10~(-4)%;( 3) When the water content is 97%,the optimal dosage of PAC and APAM is 0. 12% and 7. 0 × 10~(-4)%,the optimal dosage of PAC and CPAM is 0. 12%and 1. 4 × 10~(-3)%.
