The coagulant polyaluminium chloride treatment of fruiting fruits wastewater experimental results? Liangguo is a traditional folk food with a long history in our country. Today, the rapid development of the food industry, this product is still ahead of the domestic market with its unique flavor. China is still the country that produces preserved fruits. In recent years, the preserved fruits industry has brought considerable economic benefits to the people. However, some environmental pollution problems have also arisen at the same time: waste water, juice and sugar liquid generated during the processing of preserved fruits are often drained as waste water, and most of the domestic cold fruit waste water is directly discharged into the rivers without being directly processed , Causing the river to have a serious stench. After the sun and the moon accumulate, a large amount of cold fruit and waste water will infiltrate into the farmland, which will make the farmland become salinized and the output of grain will drop. Nowadays, the environmental problems caused by domestic cold fruit waste water discharge have become more and more serious. The treatment of such waste water has been researched and handled by the professionals. At present, there are few technologies for the research of cold fruit and waste water, so it is necessary to develop a strong and practical fruit and fruit waste water treatment technology. At present, PAC coagulation pretreatment is mainly used for the treatment of cold fruit wastewater, which can not only reduce the density of suspended solids and organic pollutants in the waste water, but also reduce the environmental hazard of discharged sewage. At present, in view of the pollution caused by Liangguo wastewater, which has become a serious problem of environmental management, the properties of waste water discharged from Lianguo fruit factory have been studied. The study found that the use of coagulation and sedimentation process of fruiting fruits is quite effective, and, in order to strengthen the coagulation pre-treatment effect of cold fruit wastewater, researchers with coagulant polyaluminum chloride treatment. The experimental results show that the non-soluble organic matter in the cold fruit wastewater is often negatively charged, and the high-valent cation in the polyaluminum chloride solution can reduce the charge on the particle surface, reduce the electrostatic repulsion force, increase the chances of agglomeration and settling of the organic particles, Organic matter in waste water decreases. Therefore, after polyaluminum chloride coagulation, sedimentation and filtration and other treatment, can make the water become clear. Moreover, the treatment of polluted wastewater with polyaluminum chloride process COD treatment effect is better, after coagulation sedimentation after treatment, the COD removal efficiency of wastewater can reach 86.19%, effluent COD up to the discharge standards. Today, polyaluminium chloride coagulant for cool fruit wastewater treatment technology has been more mature, in addition to only applied to physical and chemical treatment, the domestic processing of lagoon wastewater also introduced biochemical treatment. Moreover, the study found that physicochemical treatment with biochemical results better. At present, biochemical treatment of waste water with physical and chemical treatment has been promoted in the water treatment industry.
