Complex flocculant PASS has the abilities of neutralizing electric charge and flocculating. The experimental results show: it is feasible that the emulsion wastewater can be treated into qualified discharging water. The dosage of flocculants and pH value have been optimized by coagulation experiments. In addition the mechanism for emulsion wastewater has been studied by using Perron timed complex colorimetric method and neutralization method. Aiming at characteristics of high concentration and high CODCr emulsion wastewater the technology that emphasized on coagulation-precipitation twice has been proposed in this paper.

本文采用复合型絮凝剂处理乳化液废水，研究结果表明，乳化液废水的处理过程包括凝聚脱稳及吸附絮凝，其中絮凝是决定混凝效果的关键性步骤，复合型絮凝剂聚硅酸硫酸铝是一种既具有较强的电中和能力，又具有优异的絮凝性能的无机混凝剂，通过对乳化液废水药剂筛选实验，实验结果表明聚硅酸硫酸铝对乳化液废水是比较合适的混凝剂，并确定了药剂的最佳投药量、最佳pH值条件等操作参数，针对乳化液废水的特点，综合国内外研究成果和经验，提出了二次混凝沉淀处理方案，该方案具有处理设备结构简单、运行管理简便等优点。

Through the experiments on hydration of AH in the following sulphate（Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4）, dissoluble sulfate hydrate origining from hydration process of AH affects it's hydrous rate, hydrous rate of AH does not connect with Z/R of cation in stimulation, theory that Z/R affect hydrous rate of AH does not exist. Third, hydration of AH in dissoluble sulfate complies with dissolve-nucleate -grow theory, concentration of Ca~2+ from dissolving of CaSO_4 is higher than one of CaSO_4·2H_2O, calcium sulphate dihydrite gets a motivity of crystallization. dissoluble sulfate takes the following function: double-salt or dissoluble sulfate hydrate from hydration of AH in it becomes heterogeneous particle and a kind of nucleation catalyzer, and reduces surface barrier when DH becomes crystal because the crystal of DH precedently appears in uneven place. Results indicate hydration of AH does not conform with double-salt theory, but it conform with this mechanism: dissolve-nucleate-grow, formation of DH is an uneven nucleation and crystalizaion process.

通过对CaSO_4在Na_2SO_4 、K_2SO_4 、Rb_2SO_4 、Cs_2SO_4 、(NH_4)_2SO_4溶液中水化过程，以及CaSO_4·2H_2O、CaSO_4与以上硫酸盐反应速度、产物的研究，说明复盐理论不正确；CaSO_4在（Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO_4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4）溶液中水化，水化过程中硫酸盐水合物的析晶影响着无水硫酸钙水化，与激发剂阳离子Z/R值大小无关，阳离子的Z/R参数影响水化率的规律并不存在； 3、无水硫酸钙在可溶性硫酸盐中的水化按照溶解-成核-生长理论进行，CaSO_4达到溶解平衡时Ca~2+的浓度大于CaSO_4·2H_2O溶解平衡的Ca~2+的浓度，CaSO_4·2H_2O获得结晶的驱动力，可溶性硫酸盐起到形成晶核的作用：水化过程与CaSO_4生成复盐或析出水合物所形成的细小物相，作为异质微粒使母相中存在不均匀性，这些不均匀性有效地降低成核时的表面能位垒，使CaSO_4·2H_2O晶核优先地在这些具不均匀性的地方形成，因此这些物质起成核催化剂作用。
