intermixture

Excess sludge can be best hydrolyzed by the techniques of CaO ( 25%) and NaOH ( 5%). The protein content in the intermixture is higher, and the time of hydrolysis is shorter.

将CaO（25%，相对于干污泥的投加量）与NaOH（5%，相对干污泥的投加量）混合使用的效果最好，不仅水解时间短，而且所得水解液可过滤、蛋白质含量高。

Acting as moderator, the intermixture of strong alkali and weak base can stabilize pH values in the performance and can improve bleaching velocity, as well as the brightness of the pulp.

采用中强碱和弱碱混合物做缓冲剂，可使漂白过程的pH值既不过高，也不过低，对提高漂白速度和浆的白度有利。

The results indicated that the lowest concentrations of dyeing, electroplating, pesticide effluents and their intermixture, having significant effect on hatch and development of Penaeus chinensis embryos, were 1%, 0.4%, 1% and 0.5%, respectively;

结果表明，印染废水、电镀废水和农药废水及其混合物对中国对虾胚胎发育孵化有显著影响的最低浓度分别为1%、04%、1%和05%。
