固化处理方法是目前国内
固化处理方法是目前国内大规模处理疏浚淤泥的最适宜的处理方法。化学固化处理是在淤泥中添加固化材料,通过搅拌和混合,引起固化剂和水发生一系列物理化学反应,使其力学性质改变,从而可以改善淤泥的高含水率和低强度的性质,处理后的淤泥具有高强度、低渗透的性质。
Solidification treatment method is the most suitable treatment method
for large-scale treatment of dredged sludge in China. Chemical curing
treatment is to add curing materials to the sludge, which causes a
series of physical and chemical reactions between the curing agent and
water through stirring and mixing, so as to change its mechanical
properties, so as to improve the properties of high moisture content and
low strength of the sludge. The treated sludge has the properties of
high strength and low permeability.
淤泥固化剂可以分为高分子固化剂、化学固化剂和生物酶类固化剂。根据国情大多数采用复合型固化剂,它可以针对不同的加固目的而制定不用的配比。其优点就是成本低,而且取材方便,稳定性好。缺点就是早期强度不高。
Sludge curing agents can be divided into polymer curing agents, chemical
curing agents and biological enzyme curing agents. According to the
national conditions, most of them use composite curing agent, which can
formulate the proportion not used for different reinforcement purposes.
The utility model has the advantages of low cost, convenient material
selection and good stability. The disadvantage is that the early
strength is not high
