METHOD OF INTEGRATION OF CONCENTRATION-DEHYDRATION AND AEROBIC AIR-DRYING OF SEWAGE SLUDGE

摘要

A kind of following steps for integrating concentration and aerobic air drying dehydrated sludge: (one), which is adjusted, passes through organic reagent (3); (2) concentration (5) is remaining because of organic reagent for gravity; (3) it adjusts and passes through inorganic reagent (7); (step d) is mechanically dehydrated (8); (5) it is crushed dispersion (10); F air-dries (11) aerobicly. This method have the advantage that: (I) improves thickening efficiency sludge with improved settling property sludge, reduces concentration time, reduces its volume concentration pond; (II) is to reduce its volume dewatered sludge correspondingly, to reduce succedent heat treatment loads; (III) is dry with low energy consumption; Low speed is mobile in the drying process for (IV) mud granule, stablizes, to generate reliably in no powder; After (V) dry exhaust gas can reach environment-friendly type standard discharge,Washing; (VI) output mud granule is not compact, is conducive to using as succedent resources.
