摘要
用两段厌氧发酵,降低了造价。用厌氧生物膜法,增加厌氧菌接触反应面,提高了处理效果和沼气产气率。用A/O系统技术处理氪氮,处理效果显著。为禽粪水处理,提供了高效、简便和可靠的处理技术。
The poultry excrement water from a large poultry farm, among which COD_(cr) was 10,000—30,000mg/l, BOD_5 2,000—4,000mg/l, and NH_3-N 500—1,000mg/l respectively. By using two-stage anaerobic fermentation—A/O system to treat such high-concentrated poultry excrement water. The result showed that the rewoval rate of COD_(cr) was>94％, BOD_5>90％ and NH_3-N>70％ respectively, and also increased the production of methane and decreased the cost of construction.
