| Abstract: | Test of pre-treatment of waste leachate using coagulating sedimentation method was introduced,the test used Fe2(SO4)3 of 0.1%concentration as coagulant,the quantity of coagulant inputing,pH,agitation time and speed,sedimentation time etc. were studied,the result showed that while the quantity of coagulant inputing is 0.5 kg/m3,pH is 10,agitation speed is 110 r/min,agitation time is 60 s,the best treatment effect was achieved,removing rate of CODCr is 25%,removing rate of SS 89%. |
