Switchable fermentation device for sewage treatment

Abstract

The invention provides a switchable fermentation device for sewage treatment. The switchable fermentation device comprises a sewage flow channel, a first grating, a second grating, a transmission unit, composting boxes and a fermentation unit, wherein the fermentation unit comprises a plurality of lifting module capable of vertically accommodating composting boxes and lifting the composting boxes and a sequence adjusting module for adjusting the vertical arrangement sequence of the composting boxes. According to the invention, the actions of discharging materials at a bottom layer everyday and adding new materials at an upper layer everyday in a dynamic intermittent composting process can be completed, and the sequential position of each composting box can be adjusted according to a composting fermentation condition, so it is guaranteed that the composting boxes which leave the fermentation unit are composting boxes having undergone thorough fermentation and can be discharged in sequence according to fermentation degrees.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a switchable fermentation device for sewage treatment. Background technique [0002] Sewage treatment refers to the process of purifying, treating and reusing polluted water after use. Sewage treatment methods include physical treatment, chemical treatment and biological treatment. Which treatment method to use is determined according to the type of sewage, but no matter what kind of sewage treatment method requires solid-liquid separation, solid waste includes sludge, domestic Garbage, kitchen waste, etc. This type of garbage has a large volume, high water content, and a large proportion of organic matter. In the prior art, it will be dried, incinerated and landfilled or composted. Among them, composting is economical and practical, and the composted solid waste can be turned into fertilizer for orchards and farmland. [0003] Composting treatment refers to the method of deco...

Problems solved by technology

[0005] When fermenting with box composting, the water content, pH value, oxygen content and even the proportion of non-organic matter in the material will affect the rate and effect of fermentation. The fermentation speed of different boxes cannot be completely consistent. The lower layer has not been fermented, and the upper layer may have been The complete fermentation is completed, and the materials that have been fermented continue to be stacked, which may lead to local anaerobic
