碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 93 / The shrimp culture is a very important aquaculture industry in our country. The high concentration of organic sludge produced by shrimp will cause environmental pollution. It will save energy resource and reduce cost if we can recycle organic sludge.
In present study, we control the anaerobic digestion tank under the hydrolysis and acidogenesis conditions to investigate the most suitable reaction time of organic solid waste to deal with hydrolysis and acidogenesis. Besides, the difference of dissolution efficiency for various solid components (carbohydrate, crude protein, crude lipid) and the variation of products (BOD, total ammonia nitrogen) concentrations during the experimental period were also determined.
The results show that 45.76 ±0.11 % of suspended solids and 73.30 ±0.15 % of volatile suspended solids can be removed at reaction time of 168 hr. Dissolution efficiency of organic matter components in sludge is in the order of carbohydrate＞crude protein＞crude lipid. The carbon/nitrogen (C/N) ratio in the products is between 4 to 5. It was the highest carbon/nitrogen ratio (5.34 ±0.04) at reaction time of 168 hr.
