原水铅质量浓度超标168倍以下,采用预加碱强化混凝的应急处理工艺能使滤后水中铅稳定达标,沉淀出水中铅质量浓度低于0。
2) presharpen technique
预加碱染色法
3) alkalify
['ælkəlifai]
碱化;加碱
4) alkaline pretreatment
碱预处理
1.
Particle size distributions and its biochemical methane potential(BMP) of the sludge generated from a wastewater treatment plant(WWTP) in Ji nan city were studied in order to learn the effect of alkaline pretreatment on the sludge BMP.
以济南某生活污水处理厂的污泥为研究对象,考察碱预处理对污泥粒径和产甲烷潜力(BMP)的影响。
2.

对桉木木片在制浆前的碱预处理和热水预水解提取半纤维素的工艺进行了研究。
5) alkali pretreatment
碱预处理
1.
Effect of alkali pretreatment on selective oxidation of cotton fibers;
碱预处理对棉纤维选择性氧化的影响
2.
The results show that unbleached acetosolv pulps have low brightness compared with other pulps, oxygen delignification of acetosolv pulps needs higher NaOH charge, and alkali pretreatment of acetosolv pulps could reduce the consumption of NaOH in oxygen delignification and avoid the serious drop in pulp viscosity.
对三倍体毛白杨乙酸浆进行了TCF漂白的初步研究,发现与其他浆种比较,乙酸原浆具有较低的白度;乙酸浆进行氧脱木素时需要高的碱用量才能得到低的卡伯值,进行碱预处理可以降低氧脱木素段的碱用量,避免纸浆粘度较大程度的降低;并研究了漂白前后纸浆物理强度的变化。

补充资料：预加氯
分子式：
CAS号：
性质：又称预加氯。指在原水(或污水)的混凝、沉降和过滤处理之前的初次加氯过程。其目的是：杀菌灭藻，抑制微生物的滋长；分解水中有机物质；破坏水中胶态物质的稳定，便于混凝去除；将还原物质氧化成高价化合物，以防止腐蚀和污染水质，并利于从水中将其分离；辅助混凝过程；减少臭味等。
