Description

A changeable fermenting installation for sewage treatment

Technical Field

The invention relates to the field of sewage treatment, in particular to a switchable fermentation device for sewage treatment.

Background

The sewage treatment refers to the process of purifying, treating and recycling the polluted water body after use. The sewage treatment method includes a physical treatment method, a chemical treatment method and a biological treatment method, and the treatment method is determined according to the type of sewage, but solid-liquid separation is required in any sewage treatment method, and solid waste includes sludge, domestic waste, kitchen waste and the like. The garbage has large volume, high water content and large specific gravity of organic matters. In the prior art, drying, burning and landfill or composting treatment is carried out on the raw materials. Wherein the composting treatment is economical and practical, and the solid garbage after composting can be changed into the fertilizer for orchards and farmlands.

The composting treatment refers to a method for decomposing, decomposing and converting organic matters in the garbage into stable humus-like soil under the condition of manual control through the biochemical action of microorganisms, and the composting treatment is divided into aerobic composting and anaerobic composting, wherein the aerobic composting is a method for decomposing the organic matters by aerobic bacteria through turning and forced air supply to stabilize the organic matters.

The aerobic compost is divided into aerobic static compost, intermittent aerobic compost and continuous aerobic compost according to the process. The intermittent aerobic composting has the advantages that the materials are divided into a plurality of layers, and are cut in layers and discharged evenly, the intermittent aerobic composting has the characteristics of short fermentation period, simple treatment process and the like, the materials in the fermentation bin are fermented and decomposed from bottom to top in sequence, the decomposed bottommost layer is discharged every day, and the topmost layer is added with new materials every day. The period of static aerobic fermentation is greatly shortened due to the heat transfer from bottom to top and the inoculation of microorganisms.

When box compost is used for fermentation, the water content, the pH value, the oxygen content and even the proportion of non-organic matters of the materials can influence the fermentation speed and the fermentation effect, the fermentation speeds of different boxes cannot be completely consistent, the lower layer is not fermented, or the upper layer is completely fermented, and the materials after the fermentation are continuously stacked, so that local anaerobism can be caused.
