[0036] Below in conjunction with accompanying drawing 1, the present invention is further described in detail through specific embodiments, the following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0037] The treatment methods of container washing wastewater include pretreatment, physicochemical treatment, biochemical treatment, advanced treatment and sludge treatment in turn. The treatment processes are as follows:
[0038] 1. Pretreatment: Pretreatment includes grease trap and conditioning pool.
[0039] The main purpose of the pretreatment of the present invention is to remove large suspended solids and floating oil substances, and to adjust the water quality and quantity, which is beneficial to the subsequent stable treatment.
[0040] The grease trap is used to remove suspended solids and oil slicks in the wastewater. Since the density of oil is smaller than that of water, when the oily wastewater fl...
