Embodiment 1

[0033] The invention provides a treatment method for winery wastewater, which is used to treat production wastewater and domestic sewage produced by wineries, such as figure 1 As shown, the wastewater is first mixed with the domestic sewage treated by anaerobic fermentation and then anaerobic treatment is performed. After the anaerobic treatment, the mixed wastewater is aerated, and the water is discharged after sedimentation. Further explanation, the COD concentration in the mixed wastewater is 1000-1800mg / L, the BOD concentration is 850-1000mg / L, and the SS concentration is 200-450mg / L. The production wastewater here mainly includes wine fermentation wastewater and cleaning wastewater generated after cleaning production equipment. Fermentation wastewater mainly includes organic acids, sugars and their transformation substances, and cleaning wastewater mainly includes cleaning agents, disinfectants, etc.

[0034] Such as figure 1 As shown, after the production wastewater is...

Embodiment 2

[0047] The basic content of embodiment 2 is the same as embodiment 1, and its difference is that the processing object of this embodiment is the wastewater produced by a certain winery in Yongning County, Yinchuan City. The winery has an annual output of 990 tons of wine, and the main production period of the project is mainly concentrated in September-October each year. After accounting, the domestic water consumption of the project is about 216m 3 / a, if the domestic sewage accounts for 80% of the water consumption, the domestic sewage production is 172.8m 3 / a. The production wastewater of the project mainly comes from production line equipment (tank) cleaning, ground washing and bottle washing in the filling line. Among them, the production line equipment (tank) cleaning water is 343m 3 / a, the water consumption for ground flushing is about 146m 3 / a, the water consumption of bottle washing in the filling line is about 80m 3 / a, natural gas boiler water 200m 3 / a.

Abstract

The invention relates to the field of food enterprise wastewater treatment, in particular to a method for treating wine chateau wastewater. The method comprises the following steps: mixing wastewaterwith domestic sewage which is added with a disinfectant and is subjected to anaerobic fermentation treatment, carrying out anaerobic treatment, and carrying out aeration treatment. By combining anaerobic treatment and aeration and utilizing the action of anaerobic bacteria, organic matters are hydrolyzed, acidified and methanated, so that the organic matters in the wastewater are removed, the biodegradability of the wastewater is improved, the subsequent aerobic treatment is facilitated, the operation is stable, the treatment efficiency is high, the process flow is simple and convenient, the energy consumption is low, and meanwhile, the zero emission of the wastewater is realized.

Description

technical field [0001] The invention relates to the field of waste water treatment in food enterprises, in particular to a treatment method for winery waste water. Background technique [0002] Wine is an alcoholic beverage made from fermented grape juice. Its production process is as follows: grape raw material sorting, crushing, separation, clarification, fermentation (adding distiller's mother), raw wine storage, blending, and canning. Winery wastewater is composed of production wastewater and domestic sewage. The production process mainly produces fermentation wastewater and cleaning wastewater. Fermentation wastewater mainly includes organic acids, sugars and their transformation substances, and cleaning wastewater mainly includes cleaning agents and disinfectants. This type of winery wastewater has the characteristics of small discharge, high concentration of organic matter, and strong seasonality, which has a significant impact on the environment. [0003] At presen...
