Problems solved by technology

But there are also many problems: (1) High water content, reaching 70%-80%, increased energy consumption for incineration, high processing and operating costs, direct landfill is likely to penetrate the surface, enter the deep underground, and pollute groundwater
(2) The content of microorganisms and pathogens is high. If it is not treated and directly landfilled or discharged into the sea, it is likely to pollute the land, air and water.
(3) Containing heavy metals such as mercury, chromium, arsenic, etc., it is easy to pollute the soil if it is directly used without treatment, causing irreversible degradation of cultivated land and seriously polluting the environment
Conforms to "DL / T 808-2002 By-product ammonium sulfate produced by ammonia desulfurization in thermal power plants", and can be used as nitrogen fertilizer, but the appearance and quality of the product are different from the commercially available ammonium sulfate, making it difficult to popularize and apply

Abstract

The invention belongs to the field of environmental protection, and particularly relates to a high-nitrogen forest base fertilizer and a production method thereof, wherein the raw materials of the high-nitrogen forest base fertilizer comprise petrochemical residual activated sludge, waste fungus bran, power plant by-product ammonium sulfate, a composite passivating agent, soybean whey syrup, bran, a fermentation bacterial agent and a mineral raw material. The production method of the high-nitrogen forest base fertilizer comprises treatment on raw materials, material mixing, high-temperature fermentation, rear-laying composting, material drying and material adjusting. According to the present invention, the petrochemical residual activated sludge, the waste fungus bran and the power plant by-product ammonium sulfate are used as the raw materials to produce the high-nitrogen forest base fertilizer, such that the method belongs to the resource recycling field, is the efficient environmental resource recycling method with characteristics of simple production process, low investment cost and low energy consumption, can change the waste into the treasure, and provides significant environmental benefits and social benefits.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a high-nitrogen tree base fertilizer and a production method thereof. Background technique [0002] After the sewage is treated by the activated sludge method, the material deposited in the secondary sedimentation tank is called activated sludge, and the discharged part is called residual activated sludge. In addition to microorganisms, parasites, suspended matter and a small amount of toxic and harmful heavy metals and other harmful chemicals, petrochemical residual activated sludge also contains some nutrients such as nitrogen and phosphorus. The petrochemical surplus activated sludge belongs to industrial solid waste, and the final disposal of the petrochemical surplus activated sludge is a very complicated issue. The principle of my country's treatment and disposal of industrial solid waste is "harmless, reduced, and resourceful". In recent years, countri...
