Improvement to red mud mainly is to be used for building and therefrom to extract utility at present, and through a large amount of experimental study work, the comprehensive utilization of Bayer process red mud does not still have substantial progress.The application of red mud from sintering process aspect construction material entered the large-scale production stage, and accumulated the knowhow of decades.Because molasses alcohol waste liquid produces certain seasonality is arranged, its utilization mainly is to do on chemical fertilizer and the feed, is in addition to extract some utilities, has also obtained some and has fully utilized preferably.But some method is subjected to seasonal control bigger, is not effectively brought into play.Though some method effect is pretty good, cost is higher relatively.Hence one can see that, and at present some is comparatively feasible to the processing of red mud and molasses alcohol waste liquid, but it is higher or be subjected to seasonal effect also to exist cost, makes to use to be subjected to certain restriction.
Summary of the invention
The purpose of this invention is to provide and a kind ofly handle red mud and molasses alcohol waste liquid simultaneously, and make and for the high-quality soil of plant growing the utilization of molasses-spirit not to be subject to seasonal restrictions, reduce red mud piling up land occupation resource, the low-cost method that reduces environmental pollution.
A kind of aluminium manufacturer mine tailing red mud that the present invention relates to and molasses alcohol waste liquid fermentation system high-quality soil, it is characterized in that the process residue that stays after aluminium manufacturer is with extraction aluminium such as Bayer process, sintering process is a red mud, Main Ingredients and Appearance is for having silico-calcium matter composition, irony composition, aluminium matter composition.Molasses alcohol waste liquid is that the waste liquid that produces behind the raw material production alcohol is done with molasses in sugar refinery, and the outer more organic substance that contains dewaters.Red mud is alkalescence, and pH value is at 9-11, and molasses alcohol waste liquid is acid, pH value is at 3-6.5, and red mud mixes in varing proportions with molasses alcohol waste liquid, the two acid-base neutralization, be placed in the cement tub and add saccharomycete and bacterium, on cover film to the uniform temperature after fermentation, make high-quality soil.
Concrete steps are:
(1) Bayer process red mud and molasses alcohol waste liquid are 8 with weight ratio: 1-5: 5 ratio mixing and stirring;
(2) place step (1) gained mixture cement tub or other containers under daylight, add that to account for weight of material percentage be that ferment bacterial classification or the anaerobic bacteria of 1-10% stirs, top Complex lid plastic film, play water proof and insulation effect, allow material ferment, the temperature of mixture is 60-100 ℃ in the control flume;
(3) open film after leaving standstill a couple of days, add again after stirring that to account for weight of material percentage be that ferment bacterial classification or the anaerobic bacteria of 1-10% stirs, above Complex lid plastic film, play water proof and insulation effect, allow material ferment, the temperature of mixture is 60-100 ℃ in the control flume;
(4) repeating step (2), (3) 1 to 2 times are made soil after 10 days-30 days.
Technology of the present invention is simple, needs equipment few, handles two kinds of harmful substances simultaneously, and is with low cost, but generalization is strong in the application, is subjected to the restriction in season few, and the soil of making can be used for ploughing or restore vegetation, plays the protection environment, controls the purpose of harmful mitigation.
