Harmless resourceful treatment system for vinasse waste and method for producing humic acid

Abstract

The invention discloses a harmless resourceful treatment system for vinasse waste. The system comprises a vinasse waste conveyer belt, a vinasse waste delivery pipe and a treatment device, wherein thetreatment device consists of a crusher, a homogenizer, an anaerobic fermentation tank, an aerobic fermentation tank, a multiphase separator, an extraction and separation device and a carbonization device; the homogenizer is used for delivering the mixed and emulsified materials to the anaerobic fermentation tank through a connection pipe; the liquid outlet of the aerobic fermentation tank is communicated with the feeding port of the multiphase separator through a connection pipe; and intermediate carbon generated by the extraction and separation device via extraction is delivered into the carbonization device through a connection pipe. Compared with the prior art, the system carries out harmless treatment and resourceful utilization on the vinasse waste in the wineries, thereby thoroughlyrealizing harmless discharging of the vinasse waste after the treatment and discharging no harmful substances in the treatment process. According to the system, the sludge is recycled to produce high-value humic acid products and biochar raw materials, thereby greatly improving the economy and solving the environment pollution problems of the sludge factories.

Description

technical field [0001] The invention relates to the field of coal mining waste treatment, in particular to a harmless resource treatment system for distiller's grain waste and a method for producing humic acid. Background technique [0002] Distiller's grains and distiller's grains wastewater are organic wastes with high concentration, high temperature and high suspended matter. It mainly contains residual starch, crude protein, cellulose, various inorganic salts and bacterial protein and other substances. Most of the current treatment methods use distiller's grains as fertilizer or feed after anaerobic and aerobic fermentation, which has low utilization efficiency, and distiller's grains wastewater cannot be effectively utilized, and the waste gas and waste liquid produced by fermentation are difficult to treat. Contents of the invention [0003] The purpose of the present invention is to provide a solution to the above problems, a treatment system for the harmless resou...
