Description
Technical Field
The invention belongs to the field of environmental management materials, and particularly relates to flexible artificial soil and a preparation method thereof.
Background
The re-greening treatment of mines is the target of environmental treatment in many polluted areas. The traditional soil greening method usually adopts the modes of sowing grass seeds or manually moving soil and covering soil. Because the soil of the mine is barren and has larger pollution, the survival rate of the mode of sowing the grass seeds is extremely low, and the method belongs to 'eating by the sky'; the mode of manual soil moving and soil covering often causes ecological damage of soil taking areas, and forms the situation of pollution treatment. In sharp contrast to this: the current situation of sludge treatment is not optimistic, more than 2800 sewage treatment plants are built in China, and in the next 10 years, thousands of sewage treatment plants are newly built in China, the sewage treatment capacity of cities and towns in China reaches about 343 billions of cubic meters, the production amount of dewatered sludge is nearly 2200 million tons, and 80% of sludge is not properly treated. The existing treatment mode is sludge dewatering and then landfill, but because the sludge has the unique characteristic of meeting hydrated mud, the sludge is often re-slimed in the soaking process of rainwater, and the serious safety risk can be caused.
Therefore, if the sludge can be applied to the mine greening treatment, the treatment pressure of the sludge can be reduced, and the mine environment can be obviously improved.
Disclosure of Invention
The invention aims to provide flexible artificial soil to realize the application of sludge in mine greening.
In the scheme, the flexible artificial soil comprises the following raw materials in parts by weight: 80-100 parts of sludge, 10-15 parts of a refuse landfill fiber covering material, 2-4 parts of carboxymethyl cellulose, 1-2 parts of sodium carboxymethyl starch and 3-5 parts of modified bentonite; the refuse landfill fiber covering material comprises the following raw materials in parts by weight: 5-30 parts of straw, 5-30 parts of paper, 5-20 parts of paper pulp sludge, 20-50 parts of kaolin, 0.01-0.1 part of eucalyptus bark and 0.01-0.5 part of microbial strain solution; the microbial strain solution is spore strain solution.
The beneficial effect of this scheme: the scheme selects the sludge as the base material and is matched with the carboxymethyl cellulose, the sodium carboxymethyl starch and the modified bentonite, so that the flexible artificial soil has better adhesion seepage-proofing capacity for garbage substances such as plastics, rubber and the like while meeting the spraying requirement, and has the function of locking nutrient substances and water. The straw, the eucalyptus bark and the paper pulp sludge in the refuse landfill fiber covering material form a water-gas channel to play a role in loosening the soil; simultaneously, the requirements of the covering on environmental protection, ecology and degradability are met. The decomposition of organic matters in the sludge is realized by utilizing spore strain solution in the refuse landfill fiber covering material, the sludge structure is improved, and the odor of the sludge is prevented. According to the scheme, the sludge modification is realized by mixing the raw materials; meanwhile, the plants decompose, absorb and efficiently utilize the nutrient components in the sludge, so that the waste is changed into valuable, and the resource utilization of industrial wastes is realized; achieving the effect of treating waste by waste.
The process for preparing a fibrous cover material for landfill refers to the patent of applicant with application number CN201410623770.1 entitled fibrous cover material for landfill.
Further, MP033 modified bentonite is selected as the modified bentonite. The MP033 modified bentonite has excellent thixotropy and thickening effect.
