摘要

摘要: 酱香型白酒生产废水具有高渣砂、高悬浮物、高有机物浓度的特点，因此预处理工艺是其废水处理的关键环节。白酒酿造过程中产生的渣料、糠壳如不能高效去除，会导致后端废水处理工艺运行负荷高、设备严重损坏，甚至出水不能稳定达标。在贵州茅台股份有限公司下属中华污水处理厂进行了强化预处理测试，采用一种新型的网带式固液快速分离设备考察了不同处理精度下的渣砂拦截效果、处理能力、能耗物耗水平，并对废水资源化进行了可行性评估。结果表明，网带式固液快速分离设备处理效果远优于现状预处理工艺，在不同的生产轮次和工况下对200 μm以上渣砂综合去除效率均可达到90%以上，且占地节省62%，吨水运行电耗降低80%，理论臭气产生量降低90%。另外，由于采用了极高精度的过滤网带，固液快速分离设备可对酒糟中的蛋白质、脂肪类物质进行有效回收，为酱香型白酒生产废水的绿色低碳运行提供了可行的技术支撑。

Abstract: The wastewater from the production of Sauce-flavored Baijiu is characterized by high concentrations of slag sand， suspended solids， and organic matter， and the pretreatment process is a key step in wastewater treatment. If the by-products such as dregs and husks generated during the Baijiu brewing process are not removed efficiently， they will impose an extremely high operational load on the subsequent wastewater treatment processes. Additionally， the presence of these by-products can cause severe damage to the equipment. The abrasion and clogging caused by slag sand and other substances may reduce the service life and efficiency of the equipment， resulting in frequent maintenance， higher replacement costs， and even unstable effluent quality. This study conducted a pretreatment enhancement test at the Zhonghua Wastewater Treatment Plant under Kweichow Moutai Co.， Ltd. Using an innovative mesh-belt solid-liquid rapid separation device， the study investigated the efficiency of slag sand removal， treatment capacity， and energy and material consumption at different treatment precision levels. It also assessed the feasibility of wastewater resource utilization. The results clearly showed that the mesh-belt solid-liquid rapid separation equipment offered significant advantages over the current pretreatment process. The comprehensive removal efficiency of slag and sand larger than 200 μm consistently reached over 90%. It not only ensured high removal efficiency for larger slag sand particles but also significantly contributed to the overall wastewater treatment process. Moreover， it saved 62% in land area， a significant advantage in terms of space utilization. In terms of energy consumption， it reduced electricity consumption for operating by 80%. In terms of environmental friendliness， it decreased theoretical odor generation by 90%. These findings provide valuable insights for improving the wastewater treatment efficiency of Sauce-flavored Baijiu production. Additionally， by using extremely high-precision filter meshes， the mesh-belt solid-liquid rapid separation device can effectively recover protein and fat from the dregs. This recovery process provides a valuable source of resources that can potentially be reused. It offers a feasible technical solution for the green and low-carbon operation of Sauce-flavored Baijiu production wastewater treatment plants.
