Example Embodiment

[0022] figure 1 This is a process flow chart of the juice processing wastewater treatment process of the present invention, which specifically includes the following process steps:

[0023] 1. The wastewater flows into the regulating tank first, which is equipped with a stirrer, and the wastewater is fully stirred to achieve a balanced water quality and quantity;

[0024] 2. The water treated in step 1 enters the air flotation tank, and is degummed by the air flotation process to remove suspended solids. In this embodiment, the air flotation degumming process uses a direct ultra-fine air flotation machine, and the hydraulic retention time is generally 0.5 to 1 hour. Directly remove more than 80% of suspended matter and about 40% of organic matter;

[0025] 3. The water treated by the air flotation process enters the anaerobic reaction tank, which is equipped with an upflow anaerobic sludge bed reactor, through anaerobic fermentation and decomposition, to further reduce the organi...

Abstract

A process for treating the sewage generated by preparing fruit juice includes such steps as regulating pH value and flow, air floating for degumming, anaerobic fermenting decomposing, aerobic treating, mud-water separation, biologic treating, physical filtering and disinfecting. Its advantages are high-effect to remove organic substances (pectin) and low cost.

Description

technical field [0001] The invention relates to a wastewater treatment process, in particular to a fruit juice processing wastewater treatment process containing high-concentration organic pectin. Background technique [0002] Juice production process, especially apple juice production process, the waste water mainly comes from washing, crushing, juicing and other processes. The waste water contains a large amount of crushed fruit chips and pectin, with high concentration of organic matter, high content of suspended matter, low pH value, and water quality. characteristics such as large changes. This wastewater must be treated to meet national standards before it can be discharged. The existing juice processing wastewater treatment process generally uses anaerobic sedimentation tanks for core treatment. The treatment effect for this wastewater containing high concentrations of pectin-like organic matter is not ideal, and the effluent quality is difficult to meet the discharg...
