Biological Treatment of Concentrated Sugar Beet Wastes.

摘要

A study of the variables influencing a closed loop recirculating flume water system for conveying sugarbeets for processing was conducted at Longmont,CO. Settleable solids were removed by screening,addition of milk of lime and settling;the concentration of dissolved solids increased daily during the processing season. The increasing concentration caused no problem provided the pH was 10or greater and that the water temperature did not exceed 20C. A deep anaerobic pond received surplus system waters and the total system waters when operations ceased. Anaerobic digestion was aided by addition of nutrients and odors reduced by surface aeration. Water eventually met discharge standards,and was used the second year to fill the system.
