Embodiment 1

[0020] The present invention provides the following technical solutions: a method for treating sweet rice wine production wastewater, comprising the following steps:

[0021] A. First, the sweet rice wine production wastewater is discharged into the sedimentation tank after coarse filtration, and the flocculant is dropped into the sedimentation tank for sedimentation treatment;

[0022] B. Pump the upper water body after settlement to the degradation tank for microbial degradation;

[0023] C. Discharge the water body degraded by microorganisms into the purification pool, and put the purification agent into the purification pool for purification treatment;

[0024] D. Finally, the purified water is filtered through a fine filter and discharged to the outside for reuse.

[0025] In this embodiment, a coarse filter is used for the coarse filtration in step A, and the coarse filtration removes large particles of impurities that are not easy to settle in the wastewater.

Abstract

The invention discloses a method for processing production wastewater of sweet yellow rice wine which comprises the following steps: A, firstly, coarsely filtering production wastewater of sweet yellow rice wine, discharging the wastewater into a sedimentation tank, and adding a flocculating agent into the sedimentation tank for sedimentation; B, pumping a settled upper water body into a degradation tank for microbial degradation; C, discharging a water body subjected to microbial degradation into a purification tank, and adding a purifying agent into the purification tank for purification treatment; and D, finally filtering the purified water through a fine filter screen, and discharging the filtered water to the outside for reuse. The method provided by the invention is simple to operate, can effectively remove harmful substances in the wastewater, greatly reduces the SS content in the wastewater, has high BOD and COD removal rate of the processed wastewater, and reaches the specified discharge standard.

Description

technical field [0001] The invention relates to the technical field of treating yellow rice wine production wastewater, in particular to a method for treating sweet rice wine production wastewater. Background technique [0002] Sweet rice wine is a national traditional fine wine for migratory birds in the history of our country. The ligament development of the rice wine industry has also brought about serious environmental pollution problems. The waste water discharged from the production of rice wine has high organic pollutant content and high oxygen consumption. Entering the river will seriously pollute the water body, posing a serious threat to industrial and agricultural production, residents' life and aquaculture. Some rice wine factories use a combination of anaerobic and aerobic biochemical treatment systems to treat wastewater. [0003] The waste water from the production of sweet rice wine mainly comes from washing water, flushing water, cooling water and rice dist...
