Preparation process of carbon method lime sludge fermenting bacteria soil for improving acid soil

Abstract

The invention belongs to the utilization of lime sludge in sugar manufacturing by a carbon method. The process comprises the following steps of: casting molasses alcohol waste mash to an excrement alcaligene bacteria liquid according to the inoculum size which is 0.5% of waste mash liquid, introducing air to ferment, wherein the PH value of the excrement alcaligene fermenting waste mash reaches about 5; further, mixing Cellulomonas flavigena bacteria liquid to fresh bagasse according to the inoculum size which is 0.5% of the fresh bagasse, and uniformly mixing; then, mixing the waste mash after fermentation of excrement alcaligene bacteria according to 10% of sludge amount, the inoculated bagasse according to 30% of sludge amount with lime sludge; uniformly mixing, composting to ferment, controlling the fermenting temperature at about 40 DEG C; and when the pH value of the mixed bacteria soil reaches about 8, obtaining the carbon method lime sludge fermenting bacteria soil. The bacteria soil is applied to red soil, so that red soil is loosened, and rhizospheric microorganisms of crops increase actively so as to accelerate growth of root systems of the crops and stem leaves. The bacteria soil solves the problem that red soil is hardened due to the lime sludge generated by sugar manufacturing by the carbon method applied to the acidic red soil, and the production of crops is increased.

Description

technical field [0001] The invention relates to the development and utilization of carbon filter sludge in sugar factories with carbonation process technology, in particular to a process for preparing carbon filter sludge bacteria soil by treating Alcaligenes faecalis fermentation liquid. Background technique [0002] my country is one of the earliest countries to use sugarcane to make sugar, with a history of more than 2,000 years. At present, the domestic sugarcane sugar production processes mainly include sulfurous acid method (also called sulfurous method) and carbonic acid method (also called carbon method). After the sugarcane is harvested, the leaves, shoots, and roots are removed first, and then pretreated, broken into flakes or filaments, so that the sugarcane fiber tissue is torn, the sugar cells are fully broken, and the cane juice is further squeezed out. At this time, it is necessary to press The sugarcane juice is cleaned, the purpose of which is to clarify th...

Problems solved by technology

The main way out of the filter mud is as agricultural fertilizer. However, when this untreated filter mud is applied to acidic red soil, although it can also produce some beneficial effects and increase the yield of crops, this kind of filter mud is used in farmland. Medium application often causes soil compaction, requiring farmers to constantly loosen the soil, which greatly increases the workload of farmers, so farmers basically do not accept this untreated filter mud

However, due to the good quality of the sugar obtained by carbon-based sugar production, which is a necessary raw material for enterprises such as beverages and pharmaceuticals, and the preference of some people for carbon-based sugar, so far, some enterprises still use carbon-based sugar production. The carbon filter sludge is unavoidable

For example: a sugar company in Yunnan Province still uses the carbon method to produce sugar, and the annual discharge of the filter mud produced is about 12,000 tons. Over the years, it has accumulated more than 300,000 tons of filter mud, which is piled up like a mountain and cannot be used.
