METHOD OF TREATING WASTE WATER SLUDGE SEDIMENT BEFORE DEHYDRATION FILTRATION

摘要

FIELD: waste water treatment. SUBSTANCE: invention is designed for use in fur dehydration shops, on waste disposal plants, and at domestic sewage biochemical treatment stations. Sediment is treated by a coagulant based on aluminum hydroxochlorides immediately before transferring it on vacuum filter without special stirring. Coagulant consumption is 5.0-6.0% based on the weight of solid substance of the sediment being treated. Dehydrated sediment can be used as fertilizer. EFFECT: reduced investment volume.
