| 摘 要： | 采用添加促发剂和增素剂的方法，对城市污水厂污泥进行了除臭去水增有机质效果研究。结果表明，随着促发剂的添加，污泥粘稠度明显下降，水分含量降低近50％。气味由腐臭味慢慢转变为无臭味，但最后现出酸臭味；在24％的促发剂条件下，随着增素剂的量逐渐增加，污泥变得越来越松散；气味由酸腐味转变为泥草味，直至带有氨味的转变。在养分上，处理后有机质、全氮、五氧化二磷、氧化钾的含量范围分别为49．68％-63．89％，2．216％-3．630％，1．428％-1．696％，1．077％-1．467％。综合各种堆肥处理，以污泥＋24％促发剂＋16％-24％增素剂处理效果较好。

| Abstract: | The sludge from urban wastewater treatment plant,compost effect has been evaluated by using the method of adding Fermentation accelerant and increased nutrient agent here.Results indicated as following: as Fermentation accelerant adding from 8% to 40%,sludge viscosity consistency and water content is decline trend.The sludge odor from rot slowly change to no odor but turned out acid odor at the end of composting;In the condition of 24% of Fermentation accelerant,as increased nutrient agent adding from 8% to 32%,the sludge composting became increasingly loose and water slowly reduced;its odor change from rot to mud grass odor,until with ammonia odor.In the nutrients,full nitrogen content,five oxidation second phosphorus content,oxidation potassium content,oxidation calcium content of the deferent treatment compost ranged respectively for 49.68%~63.89%,2.216%~3.630%,1.428 %~1.696%,1.077%~1.467 % at the end of composting.Comprehensive variety of composting effect,added 24% of the Fermentation accelerant and 16% of increased nutrient agent or added 24% of the Fermentation accelerant and 24% of increased nutrient agent to the sludge are better than other treatments. |
