Embodiment Construction

[0012] Such as figure 1 Shown: a trough composting method for aquaculture sewage and solid waste without odor discharge. The aquaculture sewage of the farm 1 is collected in the closed sewage pool 6 through the hidden pipe, and the solid waste is collected outside the farm through the inclined collection channel The composting pool 7 located below the ground level in the composting workshop 2 on one side; the sewage pool is set under the inclined collection channel, and the aquaculture sewage is introduced into the composting pool through the collection channel with a pump; the ratio of solid waste, aquaculture sewage and auxiliary materials in the composting system is adjusted Carry out aerobic composting; auxiliary materials can choose rice bran, mushroom dregs, plant ash, and traditional Chinese medicine dregs.

[0013] The aquaculture sewage and solid waste in the composting tank are turned over. The turning can be done manually or mechanically. At the same time, the compo...

Abstract

The invention relates to a composting method for the sewage and the solid waste on a large-scale breeding farm, and discloses a groove-type composting method for the non-stink-discharging breeding sewage and the solid waste. The breeding sewage of the breeding farm is collected into an enclosed sewage pool through a concealed pipe; the solid waste is collected into a composting pool positioned under a horizontal plane in a composting workshop on one outer side of the breeding farm; the sewage pool is arranged below an inclined collecting channel; the groove-type composting method comprises the following steps: drawing the breeding sewage into the composting pool through the collecting channel by a pump; adjusting the proportion of the solid waste, the breeding sewage and auxiliary materials in a composting system to carry out aerobic composting; raking the breeding sewage and the solid waste in a composting groove; meanwhile, aerating the composting groove through an aerating opening formed in the bottom of the composting groove; discharging the collected waste gas generated in the composting groove into the soil loaded with plants, which can be used as deodorant or fodder, outside the workshop. The groove-type composting method further eliminates stink discharge amount, increases oxygen discharge amount, and beautified environment.

Description

technical field [0001] The invention relates to farms, in particular to a composting method for sewage and solid waste gas in large farms. Background technique [0002] With the development of large-scale aquaculture, one of the consequences is the separation of aquaculture and planting links, and the generation and treatment of a large amount of aquaculture waste has become a major issue for the sustainable development of aquaculture. Relevant data show that the annual production of livestock and poultry manure in my country is 2.5-3 billion tons (fresh weight), and this figure will also increase along with the further development of my country's livestock and poultry breeding industry. According to statistics, the current utilization rate of livestock and poultry manure in my country is less than 50%, and a large part is directly discharged into the environment without treatment, which not only causes a great waste of organic resources, but also pollutes the surrounding wa...
