污泥堆肥过程中无机磷浸提形态研究

采用强制通风静态好氧堆肥与自然通风好氧堆肥相结合的堆肥方法，研究了不同秸秆填充物料对污泥堆肥中的NH4 Cl-P、Al·P、Fe—P、0一P、Ca-P含量的影响。结果表明：污泥堆肥的NH4 Cl-P、Al-P、Fe—P和O-P含量在快速堆腐阶段先降低后升高，并在后腐熟阶段趋于稳定。堆肥结束时，受“浓缩效应”影响，污泥堆肥的NH4 Cl-P、Al-P、Fe—P、O-P和Ca—P含量分别比初始值增加了1．15％～29．27％、14．29％-37．59％、8．21％～30．24％、15．98％～23．71％和160．71％-202．45％；堆肥中无机磷以NH4Cl-P、Al-P和O-P为主，分别占无...

Summary:采用强制通风静态好氧堆肥与自然通风好氧堆肥相结合的堆肥方法，研究了不同秸秆填充物料对污泥堆肥中的NH4 Cl-P、Al·P、Fe—P、0一P、Ca-P含量的影响。结果表明：污泥堆肥的NH4 Cl-P、Al-P、Fe—P和O-P含量在快速堆腐阶段先降低后升高，并在后腐熟阶段趋于稳定。堆肥结束时，受“浓缩效应”影响，污泥堆肥的NH4 Cl-P、Al-P、Fe—P、O-P和Ca—P含量分别比初始值增加了1．15％～29．27％、14．29％-37．59％、8．21％～30．24％、15．98％～23．71％和160．71％-202．45％；堆肥中无机磷以NH4Cl-P、Al-P和O-P为主，分别占无机磷总量的17．39％～23．47％、47．27％～53．91％和24．82％-25．29％。小麦秸秆段＋污泥处理通过提高Al-P和O-P含量而显著增加了污泥堆肥的无机磷含量。

The objective of this study is to investigate the transformation of inorganic phosphorus forms during co-composting of sewage sludge and straws in aerated static pile composting system and natural ventilation fermentation system. The results showed that the content of NH4 Cl- P, Al-P, Fe-P, O-P of sewage sludge compost first decreased and then increased during the rapid composting stage, and tended to be stable during the maturity stage. Because of concentration effect, the content of NH4 Cl-P, Al-P, Fe-P, O-P and Ca-P of sewage sludge compost in- creased by 1.15 % -29.27 % ,14.29 % -37.59 % ,8.21% -30.24 % ,15.98 % -23.71% ,160.71% -202.45 % ,respectively , by the end of the experiment. NH4Cl-P, Al-P and O-P formed the chief institutions of inorganic phosphorus of sewage sludge compost, and they occupied 17.39 % -23.47 % ,47.27 % - 53.91% and 24.82 % -25.29 %, respectively. The total inorganic phosphorus content of compost which consisted of sewage slu
