Seed crystal regeneration system
According to the seed crystal regeneration system, a raw water input pipeline conveys supersaturated calcium sulfate wastewater to an adjusting and pre-settling unit, and the adjusting and pre-settling unit is used for homogenizing and equalizing the received supersaturated calcium sulfate wastewater; the destabilization unit is used for destabilizing the homogenized and homogenized supersaturated calcium sulfate wastewater to reduce the saturation degree of calcium sulfate, so as to obtain a calcium sulfate sludge mixed solution; the reaction unit is used for carrying out reaction treatment on the received calcium sulfate sludge mixed liquid conveyed by the destabilization unit so as to regulate and control the pH value; the buffer unit is used for carrying out buffer storage on the calcium sulfate sludge mixed liquid subjected to pH regulation and control; the pressure stabilizing unit is used for carrying out flow stabilizing treatment on the calcium sulfate sludge mixed liquid conveyed into the seed crystal regeneration unit; and the seed crystal regeneration unit is used for performing seed crystal regeneration on the received calcium sulfate sludge mixed liquid. According to the method, the effective utilization rate of the seed crystal is increased, calcium ions and sulfate ions in raw water are efficiently removed, the dosage of the initial calcium sulfate seed crystal and the dosage of the subsequent softening agent are reduced, and the operation cost in the whole destabilization process is reduced.
一种晶种再生系统，原水输入管路将过饱和硫酸钙废水输送到调节预沉单元，调节预沉单元用于对接收的过饱和硫酸钙废水进行均质均量；脱稳单元对均质均量后的过饱和硫酸钙废水进行脱稳处理以降低硫酸钙饱和度，得到硫酸钙污泥混合液；反应单元对接收的脱稳单元输送的硫酸钙污泥混合液进行反应处理以调控pH；缓冲单元用于对调控pH后的硫酸钙污泥混合液进行缓冲存储；稳压单元对输送至晶种再生单元中的硫酸钙污泥混合液进行稳流处理；晶种再生单元用于对接收的硫酸钙污泥混合液进行晶种再生。本发明提高晶种的有效利用率，实现对原水中钙离子和硫酸根离子高效去除，降低初始硫酸钙晶种和后续软化药剂投加量，有助于降低整个脱稳过程中的运行成本。
