摘要:
A method of enhancing nitrogen and phosphate fertilizer recovery and, particularly, to using sewage sludge and corn stover to enhance nitrogen and phosphate fertilizer recovery. The methods can further use ferric chloride as a catalyst to further enhance nitrogen recovery. The fertilizer can be produced by hydrothermally carbonizing a mixture including about 20% of sewage sludge and about 30% of corn stover.
