Abstract

The invention belongs to the technical field of wastewater treatment and particularly relates to a high-efficiency oil eliminator and an oily wastewater pretreatment system with the high-efficiency oil eliminator. The high-efficiency oil eliminator comprises at least two stages of air floatation treatment devices. An air floatation treatment device at each stage is communicated with an adjacent air floatation treatment device along a water flowing direction. A sludge hopper is arranged on the side of each air floatation treatment device. A sludge scraper which is used for scraping floating sludge in the air flotation treatment device to the sludge hopper is arranged on the upper side of the air flotation treatment device at each stage. The oil eliminator additionally comprises an air dissolving water pump which is used for delivering air dissolving water to the air flotation treatment device through a water delivery pipe. The oily wastewater pretreatment system consists of a high-concentration oily wastewater pretreatment section and a low-concentration oily wastewater pretreatment section. The oily wastewater pretreatment system has the advantages that since a high-concentration and low-concentration oily wastewater quality-based treatment process route is adopted, the operating cost is low and the removal efficiency or degradation efficiency of pollutants is high; and the system is also suitable for pretreatment of all other kinds of high-concentration oily wastewater which is difficult to degrade, or is matched with process units.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an oily wastewater pretreatment system and a high-efficiency oil remover arranged in the system. Background technique [0002] In recent years, the concept of circular economy has been deeply rooted in the hearts of the people. The recycling and processing of waste oil has sprung up like bamboo shoots after the spring rain, and has developed vigorously, which has greatly reduced the environmental pollution of oily wastewater and effectively promoted the progress of waste oil recycling. However, due to the limitation of waste oil regeneration technology, oily wastewater with large oil content, high pollutant concentration, complex molecular structure and difficult to degrade will inevitably be produced in the process of waste oil regeneration. Whether this kind of oily wastewater can be effectively treated is not only an issue of environmental protection, but...
