选用天然风化煤和pH 3.63的酒厂废弃物酒糟、MV菌剂为活化剂,与PB、PC微晶化磷矿粉在30℃下发酵研究对枸溶性磷的活化效果。结果表明,MV菌剂促进微晶磷矿粉有效P的溶解,且磷矿粉变细解磷效果增强;酒糟、风化煤促进微晶磷矿粉有效磷的溶解;MV菌条件下的酒糟、风化煤有利于微晶磷矿粉的活化,有效磷含量在25d达最高;酒糟对微晶磷矿粉的活化效应2∶1>1∶1,25d枸溶性磷J6、J8、J2和J4分别比对照J净增长了1.63%,1.42%,1.32%及1.22%;MV菌条件下风化煤参与的发酵,25d处理F6、F8、F4和F2枸溶性磷分别比对照F增长了2.15%,2.13%,1.82%和1.77%。
We use naturally weathered coal and wine distiller ’s grains with pH value of 3.63, MV agent as activator, and PB, PC microcrystalline phosphate rock at 30 ℃ to study the effect of citric acid soluble phosphorus. The results showed that the MV agent promoted the effective P dissolution of microcrystalline phosphate rock, and the effect of dephosphorization of phosphate rock was enhanced. The lees and weathered coal promoted the dissolution of available phosphorus from microcrystalline phosphate rock. Weathering coal is beneficial to the activation of microcrystalline phosphate rock, and the effective phosphorus content reaches the highest at 25d. The activation effect of lees on microcrystalline phosphate rock is 2:1> 1:1, 25d, respectively. The soluble phosphate 6, J8, J2 and J4 Compared with control J, the net growth of F6, F8, F4 and F2 increased by 2.63%, 1.42%, 1.32% and 1.22% respectively compared with control J; %, 1.82% and 1.77% respectively.
