Description
Technical field
The invention belongs to the sand fixing technology field, relate to a kind of sand-fixation agent, complex ecological sand-fixation agent that particularly a kind of domestic sludge is processed and preparation method thereof and application.
Background technology
The method of tackling quicksand has three kinds, promptly machinery fix the sand, chemical sand-fixing and vegetative sand control.Machinery fixes the sand as sand-protecting barrier, straw checkerboard barrier etc. are set, the characteristics instant effect, but drop into greatlyyer, be not suitable for using on a large scale; Chemical sand-fixing forms a kind of impervious film at Shamian Island, and then plays the effect of Shamian Island fixed, and characteristics are instant effects, are convenient to mechanized, but have high input; Vegetative sand control: mainly be at the edge of the desert or innerland plantation protection forest or on Shamian Island, carry out the plant skinning, reduce the wind speed in desert, prevent that the desert from playing sand, and then reach the purpose of fixing the sand, plant is checked winds and fixed drifting sand, and to have a cost low, effective.
The result of study of defending and controlling sand both at home and abroad shows, in the measure of each item Prevention Technique, uses the most general with controlling sediment by plant.Utilize the plant in treating drift sand, sixty-four dollar question is how to make plant on drift sand, become to live and preservation.As everyone knows, many plants must be under the protection of sand-protecting barrier, could on active sand dune, grow.But abominable for natural condition, suffer the drift sand infringement seriously to need the local place that fix the sand rapidly, vegetative sand control is difficult to play effect in short duration, even by the dust storm deflation totally.
Mud be pollutent be again a kind of resource; And a large amount of mud is the environmental problem that solution is badly in need of in China; Existing sludge of sewage treatment plants is normally carried out landfill, burning disposal, and these several kinds of treatment processs are land occupation not only, has high input; Also pollute the environment, it is the best outlet of sludge treatment that the disposal of mud is combined with recycling.Abundant organic matter, nitrogen, phosphorus, potassium are contained in the sewage work especially mud of domestic sewage factory, are the good organic sources of manure, are suitable as very much the fertilizer of plant; If mud and sand-fixation agent are combined; Not only can reduce the environmental pollution that causes because of mud, reduce environmental stress, can also produce sand-fixation agent product with high added value; And plant-growth is had very big promoter action, can strengthen sand-fixing effect.
Summary of the invention
Be to solve the weak point that prior art exists, primary and foremost purpose of the present invention is the complex ecological sand-fixation agent that provides a kind of domestic sludge to process.
Another object of the present invention provides the preparation method of above-mentioned sand-fixation agent.
The present invention also aims to provide the application of above-mentioned sand-fixation agent.
