Embodiment 1

[0036] An integrated solid fertilizer-liquid fertilizer production facility, comprising an aerobic composting bin (5) and an anaerobic fermentation chamber (1), the top of the aerobic composting bin is provided with a light-transmitting plate (8), and a vent is opened on the side ( 17), the bottom is laid with a ventilation pipeline (3), the ventilation pipeline is connected to the blower (14) outside the compost bin, the pipeline is covered with porous filler material (4), and the compost raw materials are laid evenly and loosely on the filler material , the top of the compost layer is covered with heat-absorbing cloth (7), and the anaerobic fermentation chamber is connected with the aerobic compost bin through the feed pipe (2);

[0037] The blower switch is controlled by the control box (15). When the temperature of the compost layer exceeds 60°C or the ventilation interval exceeds 30 minutes, the blower starts to work and lasts for 15 minutes;

[0038]The aerobic compostin...

Embodiment 2

[0048] An integrated production method of solid fertilizer and liquid fertilizer (using crop straw as raw material):

[0049] The first is to start the compost bin: spread fresh wood chips evenly on the ventilation pipeline laid in the bottom of the compost bin, and then chop the straw (chopped to about 1~3cm, and remove stones, plastic waste and other debris at the same time ) mixed evenly with aerobic strains and placed in the compost bin, and finally covered with heat-absorbing cloth on the top of the pile.

[0050] After the start-up is successful, the temperature in the compost bin will gradually increase under the action of microorganisms, and the blower will intermittently blow air into the compost bin under program control to provide oxygen for fermentation; Sunlight forms a greenhouse in the compost bin, which helps to increase the temperature of the composting process. On the one hand, the heat-absorbing cloth plays a role in heat preservation and heat absorption of ...

Abstract

The invention relates to a solid fertilizer-liquid fertilizer integrated production facility and method. The solid fertilizer-liquid fertilizer integrated production facility comprises an aerobic composting silo and an anaerobic fermentation room, wherein the side of the aerobic composting silo is provided with a ventilating opening, and the bottom part is paved with a ventilating pipeline; a temperature sensor is arranged in the composting silo, and the ventilating pipeline is connected with a blower outside the composting silo; a porous filler is paved on the pipeline, and the on and off ofthe blower are controlled by temperature and time jointly so as to feed air into the composting silo. The top part of the composting silo is provided with a light-transmitting plate, and heat-absorbing cloth covers the top part of a composting layer so as to have a heating and heat insulation effect on a compost body. The anaerobic fermentation room is connected with the aerobic composting silo through a feeding pipe; percolate generated during composting enters the anaerobic fermentation room through the feeding pipe; after fermenting, the percolate can be used as the fluid fertilizer or microorganism inoculum to be sprayed on the composting layer. The solid fertilizer-liquid fertilizer integrated production facility has the advantages that an improved idle household biogas digester is utilized to produce fertilizer, resources are saved, and environment protection is achieved.

Description

technical field [0001] The invention provides a method for coupling aerobic composting and anaerobic fermentation to treat rural agricultural waste and rural organic domestic garbage, belongs to the technical field of waste resource utilization, and specifically relates to a solid fertilizer-liquid fertilizer integrated production facility and production method. Background technique [0002] As the yield per mu of crops has increased year by year, the application of chemical fertilizers and pesticides has also increased significantly. However, excessive use of chemical fertilizers and pesticides has also caused irreversible damage to the ecological environment. Therefore, reducing the use of chemical fertilizers and pesticides is imperative. However, due to the reasons of production efficiency and cost, organic fertilizers have not been used in rural areas to replace chemical fertilizers on a large scale. At the same time, the amount of domestic garbage and agricultural w...
