Abstract
The invention relates to a riverway sludge resource utilization method. The method realizes resource utilization of the sludge after the river dredging to fire clay bricks in certain conditions of aperture and pressure by use of the sludge and other added components. The method provided by the invention has the advantages that the utilization technology is simple and convenient to operate; the resource utilization rate of the sludge is high; the resource utilization is economical and feasible; the problems of no place for storing a great quantity of sludge, environmental pollution and the like can be solved; and the resource utilization method deserves popularization.
Description
Technical field
The present invention relates to the method that a kind of riverway sludge resource utilization is used.
Background technology
In recent years, be to solve the black smelly pollution problem that waits in river course, government has started a large amount of desilting work, though largely can solve pollution of river problem, also cause desilting simultaneously after a large amount of mud do not have secondary environmental problems such as place stacking.Seek the outlet of final riverway sludge, become the extremely urgent hot issue that needs solution of government.
Summary of the invention
The objective of the invention is to realize the efficient application method of riverway sludge resource utilization, the integrated processes that utilizes mud to cooperate with other added ingredientss, the resource utilization application purpose of realization riverway sludge, proposition is economical, feasible riverway sludge utilizes method.
Efficient application method to the riverway sludge resource utilization is carried out according to the following steps; With mud 60～80 weight parts, kaolin 5～10 weight parts, water glass 5～10 weight parts, silica sand 3～10 weight parts, feldspar 2～10 weight parts; Grind above-mentioned raw materials with ball mill, make above-mentioned each component aperture at 150～200 orders., under normal temperature condition, evenly stir at normal temperature, mix more than 48 hours.The employing vacuum pump is a power, and pressure-controlling is at 0.1～0.6MPa, the mixing raw material after being squeezed into.Adopting the preparation method of common brick to carry out sintering mixing raw material prepares clay brick, obtains the clay brick finished product.Because of in the clay brick sintering process; Added materials such as kaolin, water glass, silica sand, feldspar, the sintering procedure of clay brick is simpler and easy, and finished product has small aperture; Has good acoustically effective; Individual light weight, thermal conductivity are little, have high-intensity performance, can directly be used for industries such as building.
The characteristics of this method are to utilize technology, method simple, easy to operate, and the recycling rate of mud is high, and is economical, feasible, and can solve a large amount of mud does not have problems such as place stacking and contaminate environment, is a kind of method that is worthy to be popularized.
Embodiment
