Problems solved by technology

On December 24, 2014, the applicant applied for "Method for Preparing Organic Fertilizer Using Sugar Filter Mud" (Application No.: 201410813376), "A Method for Energy-saving and Environmental Protection Treatment of Municipal Sludge" (Application No.: 201410813331) and "A Method for Producing Decomposed Organic Raw Materials Using Livestock Manure" (Application No.: 201410813377) and other six patents on organic solid waste treatment and resource utilization. These patents can achieve the above technological breakthroughs, but the realization of the process route fixed assets The investment cost is high, and the practical popularization and use will be subject to certain restrictions. There are certain difficulties in the rapid promotion and application of large areas in the society. It is difficult to realize the environmental protection treatment and resource utilization of a large amount of organic solid waste in the society in the short term.

Embodiment 1

[0045] see figure 1 Shown is the process flow diagram of Embodiment 1 of the method for preparing fertilizer from organic solid waste in the present invention. In this example, the method of using organic solid waste to prepare fertilizer is to roll the sugar filter sludge with a water content of 75% into a pan with a size of 3500mm in length, 2000mm in width, and 350mm in height, and the bottom and surrounding areas are uniform. In the air-permeable fermentation tray, the fermentation trays containing the sugar filter mud are stacked into stacks for aerobic fermentation for 20 days, and after they are decomposed and dried into decomposed organic materials with a water content of less than 40%, they are mixed with large, medium and trace amounts required by plants. Nutrient elements are combined to produce organic-inorganic compound fertilizer products. Its production steps are as follows:

Embodiment 2

[0056] see figure 2 Shown is the process flow diagram of Embodiment 2 of the method for preparing fertilizer from organic solid waste in the present invention. In this example, the method of using organic solid waste to prepare fertilizer is to mix sugar filter mud with a water content of 70% and bagasse / pith with a water content of 45% to adjust the water content to 67.5%, and after rolling, put the The inner size of the tray is 2000mm in length, 1200mm in width, 200mm in height, and the bottom and surrounding sides of the fermentation tray are air-permeable, and then the fermentation trays containing sugar filter mud and bagasse / pith mixture are stacked into trays for aerobic fermentation for 12 days After being decomposed and dried into decomposed organic material with a water content of less than 25%, it is combined with large, medium and micronutrient elements required by plants to produce organic-inorganic compound fertilizer products. Its production steps are as follo...

Embodiment 3

[0068] see image 3 Shown is the process flow diagram of Embodiment 3 of the method for preparing fertilizer from organic solid waste in the present invention. In this embodiment, the method of utilizing organic solid waste to prepare fertilizer is to roll the sugar filter mud with a water content of 70%, and then sprinkle and mix dry powdered sugar filter mud on the surface of the sugar filter mud (fermentation reuse) material), put it into a fermentation tray with a length of 1000mm, a width of 300mm, and a height of 100mm, and the bottom and surrounding sides of the fermentation tray are all ventilated, and then the fermentation trays containing the sugar filter mud are stacked for a total of 3 days. After primary aerobic fermentation and secondary aerobic fermentation, after decomposing and drying into decomposed organic material with a water content of less than 30%, it is combined with large, medium and micronutrient elements required by plants to produce organic-inorgan...

Abstract

The invention relates to a method for preparing fertilizer by using organic solid waste. According to the method, the organic solid waste with 75%-50% of water content is crushed and/or rolled and is loaded in ventilated fermentation trays, then the fermentation trays filled with the organic solid waste are stacked for aerobic fermentation for 3-20 days, the organic solid waste is composted and dried into a composted organic material with lower than 40% of water content, and the composted organic material is applied directly as organic fertilizer or is matched with macronutrients and secondary and trace nutrient elements required by plants for production of fertilizer products. With adoption of the method, the fertilizer can be prepared from the organic solid waste in more environment-friendly, efficient and low-cost manners.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly treatment and resource recycling of sugarcane sugar-making organic waste, and in particular relates to a method for preparing organic fertilizers by utilizing organic solid waste such as sugar-making filter mud and bagasse. Background technique [0002] According to the data released by the authoritative department, the organic solid waste discharged by the whole society of our country is more than 4 billion tons every year. The main characteristics of these organic solid wastes are that they are rich in organic matter and some other nutrients, and at the same time have a high water content, averaging between 70% and 80%. direct use. If such a large amount of organic solid waste is not handled properly, it will be one of the main pollution sources of the social ecological environment; if it is treated in an energy-saving and environmentally-friendly manner and ferti...
