河湖淤泥的粒径极细,中值粒径一般为微米级。表1、表2、表3所列的数据表明,淤 泥中颗粒粒径在75微米以下的极细淤泥广州市猎德涌淤泥占67.2%、云南滇池淤泥占 99.5%、武汉黄孝河淤泥占67.9%。这种高比例极细粒径的情况使得淤泥的固化十分困难, 且固化后具有的强度很低。 The particle size of river and lake silt is very fine, and the median particle size is generally micron. The data listed in Table 1, table 2 and table 3 show that the very fine silt with particle size below 75 microns accounts for 67.2% of Guangzhou Liede Chung silt, 99.5% of Yunnan Dianchi lake silt and 67.9% of Wuhan Huangxiaohe silt. This high proportion of very fine particle size makes the solidification of sludge very difficult, and the strength after solidification is very low. 另一方面,河湖淤泥含有大量的有机成分,这从另一个角度给淤 泥的固化带来困难。因此,淤泥固化前需要进行调质处理,营造出淤泥极细颗粒能快速固化 的环境条件,降低淤泥极细颗粒固化的不利因素,使其极细颗粒间能紧密粘结或发生团聚, 从而能快速有效地进行固化。这就是本发明的宗旨。 On the other hand, river and lake silt contains a lot of organic components, which makes it difficult to solidify the silt from another point of view. Therefore, it is necessary to carry out conditioning treatment before sludge solidification to create the environmental conditions for the rapid solidification of very fine sludge particles, reduce the adverse factors for the solidification of very fine sludge particles, so that the very fine particles can be closely bonded or agglomerated, so as to solidify quickly and effectively. This is the purpose of the invention. |
