Embodiment 1

[0050] The invention provides a liquor brewing wastewater treatment system. The wastewater is collected by a pipe network and then collected into a grid well for pretreatment. After removing the distiller’s grains and large particles of suspended matter in the wastewater, it is lifted by a lift pump to a regulating tank to balance the water quality and volume; The wastewater in the adjustment tank flows into the coagulation sedimentation tank to remove fine suspended solids and colloidal particles, and the coagulation sedimentation tank is added with coagulants polyacrylamide and polyaluminum chloride. The concentrations of polyacrylamide and polyaluminum chloride are respectively 15g / m 3 And 150g / m 3 , Use the adsorption and coagulation effect of the coagulant to remove the fine suspended solids and colloidal particles in the wastewater, while adding sodium hydroxide to adjust the pH of the wastewater to 7; the wastewater in the coagulation sedimentation tank overflows into the ...

[0053] The invention provides a liquor brewing wastewater treatment system. The wastewater is collected by a pipe network and then collected into a grid well for pretreatment. After removing the distiller’s grains and large particles of suspended matter in the wastewater, it is lifted by a lift pump to a regulating tank to balance the water quality and volume; The wastewater in the adjustment tank flows into the coagulation sedimentation tank to remove fine suspended solids and colloidal particles, and the coagulation sedimentation tank is added with coagulants polyacrylamide and polyaluminum chloride. The concentrations of polyacrylamide and polyaluminum chloride are respectively 20g / m 3 And 200g / m 3 , Use the adsorption and coagulation of the coagulant to remove the fine suspended solids and colloidal particles in the wastewater, while adding potassium hydroxide to adjust the pH of the wastewater to 7.5; the wastewater in the coagulation sedimentation tank overflows into the in...

Embodiment 3

[0056] The invention provides a liquor brewing wastewater treatment system. The wastewater is collected by a pipe network and then collected into a grid well for pretreatment. After removing the distiller’s grains and large particles of suspended matter in the wastewater, it is lifted by a lift pump to a regulating tank to balance the water quality and volume; The wastewater in the adjustment tank flows into the coagulation sedimentation tank to remove fine suspended solids and colloidal particles, and the coagulation sedimentation tank is added with coagulants polyacrylamide and polyaluminum chloride. The concentrations of polyacrylamide and polyaluminum chloride are respectively 22g / m 3 And 200g / m 3 , Use the adsorption and coagulation of the coagulant to remove the fine suspended solids and colloidal particles in the wastewater, and add sodium hydroxide to adjust the pH of the wastewater to 8; the wastewater in the coagulation sedimentation tank overflows into the intermediate...

Abstract

The invention provides a Baijiu brewing wastewater treatment system. The wastewater treatment system is composed of a grid well, an adjusting tank, a coagulation precipitation tank, a middle water tank, an up-flow type anaerobic sludge bed reactor, a first-grade anoxic tank, a first-grade aerobic tank, a second-grade anoxic tank, a second-grade aerobic tank, a secondary sedimentation tank and a disinfection tank, which are connected in sequence. By adopting the Baijiu brewing wastewater treatment system provided by the invention, the process operation cost is low and the treatment effect is stable; after treated wastewater is detected, all indexes of final output water are lower than requirements of Discharge Standard of Water Pollutants for Fermentation Alcohol and Baijiu Industry (GB27631-2011); the wastewater can be directly discharged into a sewage treatment plant and is further treated.

Description

Technical field [0001] The invention relates to the field of wastewater treatment, in particular to a liquor brewing wastewater treatment system. Background technique [0002] my country's liquor culture is extensive and profound. As a special commodity that meets people's material and spiritual needs, liquor products are closely connected with the culture of the place of origin. Drinking is not only a material enjoyment, but also an emotional carrier for people to express their feelings, enhance friendship, and expand communication. It is an indispensable adjustment in interpersonal relationships. According to statistics, in 2015, there were 1,563 liquor companies above designated size nationwide, with a total output of 13.128 million kiloliters of liquor and a sales revenue of 555.886 billion yuan; the cumulative export volume of liquor products was 16,188.83 kiloliters, and the total export volume was 449 million US dollars. However, liquor production creates a lot of waste w...
