Integrated white wine production waste water treatment device

Abstract

The invention relates to waste water treatment, in particular relates to an integrated white wine production waste water treatment device which is convenient to transport, easy and convenient to operate and manage, low in running cost and good in treatment effect. The integrated white wine production waste water treatment device comprises a flocculation stirring region, an inclined plate sedimentation region, a hydrolysis acidifying region, an air floating region, a biological contact oxidization region, a vertical flow sedimentation region and a sand filter region. The waste water treatment method comprises the following steps of: adding lime into the original waste water; adjusting the pH of the waste water until the waste water to be neutral; adding flocculating agent for flocculation and sedimentation; removing granular alumen ustum to improve the biochemical property of the waste water; performing anaerobic hydrolysis, and degrading large-molecule organics in the waste water into small-molecule organics to improve the biochemical property of the waste water again; performing coagulation and air floating treatment on the waste water subjected to anaerobic hydrolysis; performing aerobic biological treatment on effluent; and finally performing vertical flow sedimentation and sand filtering treatment, and discharging the effluent. The integrated white wine production waste water treatment device has a compact structure and is convenient to convey and manage, safe to operate, low in running cost, high in waste water treatment capacity and suitable for waste water treatment matched with white wine production; and the organics elimination rate is high.

Description

technical field [0001] The invention relates to wastewater treatment technology, in particular to integrated treatment equipment for liquor production wastewater. Background technique [0002] Liquor production wastewater is a kind of high-concentration organic industrial wastewater, which is mainly composed of distillation pot bottom water, flushing water, fermentation tank seepage water, underground wine storage seepage water and fermentation tank blind ditch water generated during the liquor brewing process. The discharge of liquor wastewater is large. According to statistics, about 15-25 tons of wastewater is produced for every ton of liquor produced. The average annual discharge of liquor wastewater in my country is about 100 million tons. Liquor production wastewater COD, BOD 5 It has high and SS values, complex components, and acidic pH, which belongs to high-concentration organic wastewater. Wastewater has a high color and mainly contains low-carbon alcohols (ethan...

Problems solved by technology

Coagulation-sedimentation method is an effective pretreatment method, which can improve the removal rate of organic matter and the biochemical properties of wastewater, but it will be accompanied by a large amount of sludge, and the water quality after treatment is still difficult to meet the standard, and other processes are required for further treatment, and the cost is relatively high. High; membrane separation method and activated carbon adsorption method have a high removal rate of SS in wastewater, but the treatment cost is high, and cleaning is difficult; chemical oxidation method has a good removal effect on refractory organic matter, and effectively improves the biochemical efficiency of wastewater However, its complex operation process is not conducive to popularization and application; anaerobic biological method has the advantages of high load, high efficiency, low energy consumption, and energy recovery, etc., but it requires high operation and management technology; aerobic biological method Can greatly reduce COD and BOD 5 , but limited removal of phosphate and nitrogen
