Fruit juice processing wastewater treatment process

Abstract

The invention relates to the technical field of fruit juice wastewater treatment, and discloses a fruit juice processing wastewater treatment process, which comprises: 1, removing large impurities andpomace from fruit juice wastewater through a corrosion-resistant grid, feeding the wastewater into a water collection tank, pumping the wastewater into an adjusting tank by using a filtration pump, and placing a volcanic rock biological filtration material into the adjusting tank to adjust the water quality; and 2, enabling water discharged from the adjusting tank to flow into a UASB reactor. According to the invention, the UASB reactor and a hydrolytic acidification tank are matched to carry out double anaerobic-aerobic treatment; the process has the advantages of high organic load, short hydraulic retention time, good effect, good energy-saving effect and improved treatment efficiency. A glass fiber reinforced plastic grid is sleeved with polypropylene double-layer filter cloth, large impurities can be blocked through the grid, and small impurities can be blocked through the polypropylene double-layer filter cloth.

Description

technical field [0001] The invention relates to the technical field of fruit juice wastewater treatment, in particular to a fruit juice processing wastewater treatment process. Background technique [0002] Juice is made of high-quality fresh fruit as raw material, which is processed and prepared by selecting, washing and squeezing. Juice produces a large amount of high-concentration organic wastewater during the production process. Wastewater mainly comes from fruit washing, crushing, juicing and container cleaning. Wastewater mainly contains a large amount of pomace, sugars and organic acids. Generally, the COD is around 10,000mg / L. The traditional treatment process has the following disadvantages: 1. The work process is long; 2. The system has a large amount of dosing; 3. It occupies a large area and the cost of civil construction is high; 4. The treatment effect is unstable; 5. The sludge cannot be effectively used. Therefore, it is necessary to develop a low-cost, hig...
