Abstract

The invention relates to a mud dewatering and curing construction device and method and relates to the field of mud treatment. The device comprises a mud pool, an inorganic flocculation pool, an organic flocculation pool and a filtering device. A mud pump is installed in the mud pool, and a smashing rod is rotationally connected to the position, close to the mud pump, of the mud pool; crushing sheets are fixedly connected to the peripheral wall of the crushing rod, and the mud pit is fixedly connected with a first motor for driving the crushing rod to rotate; the mud pit is rotationally connected with a rotating shaft synchronously rotating with the crushing rod, and the rotating shaft is connected with a crushing assembly; the output end of the slurry pump is connected with a first sedimentation tank connected with the inorganic flocculation tank, the first sedimentation tank is connected with a second sedimentation tank connected with the organic flocculation tank, and the second sedimentation tank is connected with the filtering device. The device has the effect of ensuring that the slurry pump normally pumps slurry, it is ensured that the slurry is fully flocculated and agglomerated, and the working efficiency of slurry dehydration and solidification is improved.

Description

technical field [0001] The present application relates to the field of mud treatment, in particular to a construction device and method for mud dehydration and solidification. Background technique [0002] At present, it is a sludge treatment method that removes water from fluidized primary, concentrated or digested sludge and converts it into semi-solid or solid sludge. After dehydration, the moisture content of the sludge can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dewatering equipment. Further dehydration of the sludge is called sludge drying. , the moisture content of dried sludge is less than 10%, and the dehydration methods mainly include natural drying method, mechanical dehydration method and granulation method, among which natural drying method and mechanical dehydration method are suitable for sewage sludge. The granulation method is suitable for coagulation and sedimentation of sludge. [0003] T...
