Embodiment Construction

[0029] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0030] Such as figure 1 or figure 2Shown, this mud silt processing method, the steps of this method are as follows: one, mud silt is transported in the slurry pool, the mud silt that flows in the slurry pool is filtered in the slurry pool, and the rubbish that diameter is greater than 3mm is pulled out The machine 6 clears out the slurry pool, and the mud sludge after filtering is fully stirred in the slurry pool; two, the mud sludge left in the slurry pool and fully stirred is transported to the conditioning tank-9 by the self-priming pump 24 for conditioning Add polymeric alumina (PAC for short) and water into tank one 9, and mix the mud sludge in conditioning tank one 9 with polyalumina and water and then fully stir i...

Abstract

The invention provides a method for treating mud silt, and belongs to the technical field of mud treating methods. The method for treating mud silt solves the problems that an existing method for treating mud silt is long in time and high in cost. The method for treating mud silt includes the steps that firstly, mud silt is conveyed into a mud collecting pool, mud silt flowing into the mud collecting pool is filtered in the mud collecting pool, garbage with the diameter larger than 3 mm is removed out of the mud collecting pool through a scooping machine, and the filtered mud silt is fully stirred in the mud collecting pool; secondly, polymerized aluminum oxide and water are added; thirdly, polyacrylamide and water are added; fourthly, fully-stirred mud silt acquired in a second conditioning tank is conveyed into a filter press through a screw pump; fifthly, filter-pressing water obtained after dehydration of the filter press is drained, and mud silt forms mud cakes; sixthly, the mud cakes are conveyed outside through a conveyor belt. The method is mainly used for treating waste mud generated in the pile foundation construction process, treating efficiency is high, and treating cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mud treatment methods, and relates to a mud sludge treatment method. Background technique [0002] At present, only lakes and rivers have silt in our country, and the annual collection amount can reach at least 70 million tons. Adding the silt from urban sewers, the annual total collection amount can reach more than 100 million tons. Collecting silt is beneficial to dredging rivers, preventing water nutrient and purifying urban environment. [0003] In addition, building piling (pile foundation) technology is a cutting-edge technology in the non-excavation method. As one of the main systems of mud-water piling (pile foundation), the mud treatment system directly affects the construction progress and quality. [0004] For the processing of mud sludge, there are several processing methods in the prior art: the one is to directly pour into the sea. Doing so pollutes marine resources and has been expressly ...
