Background For some manufacturers producing fruit juices, jams, jellies, fruit cans (e.g., citrus cans), beet sugar, alcohol, coffee, textiles, bioethanol processed from beet or citrus, etc., waste water containing large amounts of pectin is produced during the production process. Because the pectin content in the wastewater is higher, pectin can cause the wastewater to be slightly acidic, and fruit acid is generated after fermentation, so that the pH value of the wastewater is reduced, the concentration of organic matters in the pectin-containing wastewater is also higher, and the direct discharge does not meet the environmental protection requirement. In order to meet the environmental protection requirement, pectin, organic matters and the like in the wastewater are required to be treated so that the quality of the effluent reaches the standard.
