After 60 days, the increase order of the fast available potassium is: blue standard lime mud field (160.2mg/kg)>moist sandy land (156.4mg/kg)>lime mud field (138.4mg/kg)> the yellow mud field (107.1mg/kg).
The contaminationmainly comes from lime procedure and washing and neutralization procedure whichform large amount of the alkaline wastewater for gelatin plant (1400t/t gelatin, pH>11)of high concentration of Ca2+( 800~930mg/L) and protein ( COD1000~2000mg/L,TN140-300mg/L).
Lime fly-ash gravel with three grade filling gradation raise compactibility by vibrating compaction method,in the condition of content of Sio2,Fe2O3,AI2O3 in fly-ash in according with the requirement,the fineness of fly-ash in main factor to effect strength and frost resistance.
Under the conditions of 5% burnt lime addition,digestion of burnt lime for 10 mins and granulation for 5 mins,the tumble index was increased from 63.43% to 65.23%,productivity from 1.671 t/(m2·h) to 1.894 t/(m2·h).
The present paper reported the results of the experimental study for the lime dissolution in the slags of CaO-CaF_2-SiO_2 System The result shows that there are some disagreements between the phase diagram of CaO-CaF_2-SiO_2 system and the investigated value.
Electron plasma induced by a focused femtosecond pulse (130 fs, 800 nm) in quartz, fused silica, K9 glass, and Soda Lime glass was investigated by pump-probe technology.
The electron relaxation processes are different: lifetime is about 170 fs in pure quartz and fused silica, and about 100 ps in K9 and Soda Lime glass.
In fixed-bed combustion of coal, the retention rates of selenium volatiles were between 11.6% and 50.7% using lime.
In the circulating fluidized-bed combustion of coal, the content of selenium in ash from the chimney was reduced to one-fourth of its original value and that in leaching water from the chimney decreased by two orders of magnitude using lime.
The thermal (phonon) conductivity of the investigated soda-lime silicate glasses increases slightly (～27-30%) with temperature from ambient up to around the glass transition.
