Abstract
The invention discloses a treating method for organic waste water. The method comprises the following steps: A, collection of organic waste water; B, primary neutralization of organic waste water: a step of pumping and transferring organic waste water to a neutralization reagent-feeding tank 1 and heating an alkaline agent in the neutralization reagent-feeding tank 1; C, primary photocatalysis of organic waste water: a step of adding a Fenton reagent into a photocatalytic reactor 1 and allowing organic waste water in the photocatalytic reactor 1 to undergo degradation under ultraviolet irradiation; D, secondary photocatalysis of organic waste water: a step of adding the Fenton reagent into a photocatalytic reactor 2 and allowing organic waste water in the photocatalytic reactor 2 to undergo degradation under ultraviolet irradiation; E, secondary neutralization of organic waste water: a step of pumping and transferring organic waste water in the photocatalytic reactor 2 to a neutralization reagent-feeding tank 2, adding limewash into the neutralization reagent-feeding tank 2, carrying out stirring and adding an aluminum polychlorid solution; F, coagulation reaction; G, discharging: a step of separating clear water at an upper layer and sunken sludge.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for treating organic waste water. Background technique [0002] At present, the treatment methods of organosilicon wastewater include physical and chemical methods, chemical methods, biological methods and their combined processes. Among them, the advanced oxidation method has been widely used because of its high treatment efficiency and strong operability, especially the photocatalytic oxidation method for refractory biodegradable Organic matter has a higher removal capacity. Since the main production raw materials are organosilicon monomers and benzene series substances, the biodegradability of wastewater is extremely poor and the acidity is extremely strong, so conventional biochemical processes cannot be used for treatment. According to the quality of the wastewater, the photocatalytic oxidation method is used for pretreatment, and a good treatm...
