摘要
Because there are plenty of clay particles in the flush fluid of Pingguo Aluminum Mine, the consolidationtechnology in geotechnical engineering was adopted to carry out the disassociation of water and soil disassociation. Inthis method, vacuum method, electro-osmosis and chemical flocculation were used comprehensively to separate soilfrom flush fluid. The experiments of the method of "vacuum + electro-osmosis" for drainage was made. After pretreat-ing the flush fluid, suction pressure was offered by the sand well in the bottom and electro-osmosis was used to drainoff water. The results of the experiment show that the good effect can be obtained in drainage when the electric gradi-ent is greater than 8.3 V/cm and the quantity of sand well is more than 6. In industrial production, it is necessary to in-crease the quantity of sand well, to arrange the electrodes rationally and to set up an intermittent electric circuit. On thebasis of the experiments , the industrial feasible flow was put forward. It may be a helpful attempt to apply consolida-tion technology to the fields of the environmental protection and so on.
