1． 在一定范围内，进脱水机污泥浓度越高，处理效果越好。因此污水含水率应在97%—99%之间，PH值在6—9之间。
2． 常规污泥脱水要加絮凝剂，加药絮凝效果好的污泥容易处理。处理出来的污泥含水量较低（75%左右）
3． 污泥脱水一般采用高效阳离子絮凝剂,但对于采用阳离子絮凝剂效果不佳的污水,可以采用碱式氯化铝(PAC)+阴离子絮凝剂.
4． 造纸厂和酒精厂污泥黏度低，纤维素含量高，同时絮凝效果好，处理量比较大。
5． 对于生活污水而言，初沉池污泥黏度低，加药絮凝效果好，容易处理。生化污泥属于比较黏的，处理量不如初沉池，且处理出来的污泥含水量较高（83%左右）
6． 生化污泥如果很长时间不处理，由于自身厌氧发酵，黏度更高且絮凝效果更差。
7． 电厂的粉煤灰容易处理，因为粉煤灰极易絮凝，且比重大，所以处理含水率低。
8． 氢氧化镁和氢氧化铝等金属类胶体废水用带机处理效果不太好。
9． 含油、油漆、汽车表面处理等污水用其它脱水机效果不好，用立毛纤维带机效果较好，因为污泥和滤带分离容易。
To use the belt press, the relationship of sewage character, disposal effect and amount
1, In some range, the condense higher, the effect better. So the moisture should be in 97%-99%, PH between 6-9.
2, Sewage dehydrating should be add PAM, the effect better, the disposal easier. The moisture of the sewage is lower.
3, Sewage dehydrating is to use cation PAM, if the effect normal, it could use PAC and anion PAM.
4, For paper making and alcohol making factory, viscosity low, fibrin content high, and the effect is perfect, the amount is large.
5, For the city sewage, viscosity low, effect is perfect.
6, For the city sewage, if biochemical sewage viscosity high, the moisture is high.
7, If biochemical sewage is not disposal at a long time, it would ferment, the effect worse.
8, The fly ash of power station is easy to disposal.
9, The effect of disposal ferrous magnesium oxide and hydrated alumina sewage is normal.
10, The effect of oil, oil paint, car surface treatment sewage is not good if use other press, they should use filter cloth press.
