求翻译：根据DLVO理论，增加的负表面电荷将会不断增加靠近表面的静电斥力，同时不断降低各种絮凝物的结合能力，因此，高负电荷的絮状物往往具有较低的絮体强度和絮凝能力，污泥絮凝性增强，絮体增大更容易沉降。是什么意思？

According to DLVO theory, increased negative surface charge will increase near the surface electrostatic repulsion, at the same time decreasing ability of flocculation and, therefore, high negative charge Floc tends to have lower strength of aggregates and flocculating capacity of sludge flocculation enhancements increase Floc easy settlement.
