Special bacteria for leachate deodorization of garbage treatment plant and using method thereof

Abstract

The invention provides special bacteria for leachate deodorization of a garbage treatment plant and a using method of the special bacteria for the leachate deodorization of the garbage treatment plant. The special bacteria for the leachate deodorization of the garbage treatment plant are characterized by comprising bacillus subtilis, moss bacteria, polymyxin, aspergillus, nocardia and water, and have a large number of microorganisms which can degrade target pollutants and survive in the pollutants independently while taking effects and use toxic substances as a sole carbon source when other nutrients reach minimum values, furthermore, the special bacteria can reproduce and metabolize the pollutants in an environment of compounds which are often combined together with some heavy metals. The special bacteria for the leachate deodorization of the garbage treatment plant disclosed by the invention can be used for waste reduction, deodorization and inhibition on forming harmful microorganisms of other pathogenic bacteria and the like of city garbage landfills, and further can be used for treating leachate generated in the burying process to lower the concentration of BOD, COD, ammonia, phosphorus, nitrite and surfactants.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a special bacteria for deodorizing leachate of a garbage treatment plant and a method for using the same. Background technique [0002] With the acceleration of urbanization and the continuous improvement of residents' living standards, the amount of municipal solid waste is also increasing rapidly. According to incomplete statistics, more than 200 cities across the country have been surrounded by domestic garbage. The annual output of domestic waste in cities and towns in my country is about 100 million tons, and the stockpile over the years has exceeded 700 million tons. Due to the huge amount of garbage, all parts of our country have begun to build garbage treatment plants to deal with the generated garbage, which greatly relieves the pressure on urban development caused by the huge amount of garbage. However, before treatment in the treatment plant, garbage is accumulated in...

Problems solved by technology

However, before being processed by the treatment plant, the garbage is piled up in the treatment plant. The long-term accumulation of garbage will cause the leakage of landfill leachate. The landfill leachate has a serious odor. If it is not treated effectively, the landfill leachate will It will seep into the ground, and the landfill leachate that seeps into the ground will enter the groundwater layer, which is extremely likely to cause considerable pollution to the urban water environment, and is even more harmful to urban sewage.
