Abstract

The invention relates to a method of using sludge to process nutritional soil. The nutritional soil comprises, by weight, 55-65% of the sludge, 15-25% of organic matter, 5-15% of coconut tree fiber, 0.1% of sludge fermentation agent, 0.1% of EM, 2-4% of perlite, 1-3% of vermiculite and 3-8% of nutritional soil conditioner. The method includes following steps: step 1, weighing raw materials; step 2, fermenting for the first time; step 3, turning, and fermenting for the second time; step 4, cooling, and adding materials; step 5, making the nutritional soil. The method has the advantages that theproblem of sludge treatment is solved, and the sludge is recycled, so that environment is protected; the nutritional soil is richer, more diverse and more comprehensive in nutrition; cost is saved, and compared with existing nutritional soil, cost of the nutritional soil is lowered substantially; the method is simple in step and convenient for popularization.

Description

technical field [0001] The invention relates to the technical field of sludge processing nutrient soil, in particular to a method for sludge processing nutrient soil. Background technique [0002] Sludge (except industrial sludge) is a kind of easily corrupt and smelly paste produced in the process of sewage treatment. It enriches the pollutants in sewage, contains a large amount of nutrients such as nitrogen and phosphorus, organic matter, virus microorganisms, Toxic and harmful substances such as parasite eggs and heavy metals will cause serious harm to the environment if they are not effectively treated and disposed of. The water content of sludge produced by urban sewage treatment plants is ≥80%, and most of the sludge is acidic, with a pH value of 4-6.5, so it is not suitable for direct use. [0003] According to the survey, 80% of the sludge in our country has not been effectively treated, and even a large part of it is directly discarded in public environments such a...
