CHEMICAL FIXING METHOD FOR LIQUID SLUDGE BY POZZOLANIC REACTION |
摘要 |
<p>A liquid aqueous sludge is transferred into a cylindrical-conical tank and agitated by blowing in air through a downwardly extending tube. A closed circulation of sludge is established between this main tank and a reagent tank by means of a recycling pump. The reagent tank overflows into the main tank. Chalk is added to the reagent tank and a pozzolanic material is added to the main tank. When the mixture of dilute sludge, chalk and possolanic material is homogeneous, it is transferred to a filter press by means of a further pump. The filter cake is collected for final storage or discharged to set slowly.</p> |
