At present, there are many disadvantages in sludge deep dewatering, so it is necessary to find a suitable sludge conditioner, which does not need to add iron salt and lime, but also can increase sludge production and improve sludge reduction efficiency. Reduce the volume of sludge cake produced by sludge dewatering and reduce the disposal pressure; Reduce operating costs. According to the specific process of deep dewatering of sludge disposal, Works Chemical uses sludge conditioner and a small amount of dewatering agent to simulate the deep dewatering process in laboratory experiments, and remarkable results have been achieved:

(1) The amount of sludge conditioner is only 3-4%, and the resulting sludge conditioner cost is only 140 yuan /tDS, which only accounts for 40% of the original sludge conditioner cost, and the sludge conditioner quickly penetrates the sludge, the reaction is fast, the operation is simple and convenient, the mud cake moisture content after press filtration is lower, and the moisture content and shear strength meet the landfill standards.

(2) The experimental formula is adopted without adding lime, and the pH of the sludge after conditioning with the sludge conditioner is 8.0. Because the pH is greatly reduced, it does not corrode the equipment, helps to reduce the release of ammonia in the sludge, and there is no lime powder dust, and the working environment does not harm the health of employees.
