Biological Waste Treatment at Elevated Temperatures and Salinities

摘要: The subject of waste treatment at elevated temperatures and salinities is, perhaps, best introduced by briefly reviewing the history, technology, fundamentals under ordinary conditions climate water quality. biological liquified human wastes as an essential municipal activity has been a development last 100 years, initiated primarily in Northwestern Europe Northeastern United States response to stream pollution epidemics cholera other water-borne diseases brought about indoor plumbing discharge wastewaters into drainage channels, streams, rivers, lakes, sea. processes were designed first remove large floatable settleable solids from streams screening sedimentation dispose these separate systems burial, drying, incineration, or fermentation. In late 1800’s, it became evident that physical removal was often not sufficient colloidal soluble organic materials also had be removed if depletion life-giving dissolved oxygen waters receiving avoided. During this period, aerating controlled time temperature, aerobic microbial growth would occur which most biologically degradable matter incorporate particulate biomass removal.
