Abstract

The invention relates to an industrial oil-containing sewage treatment agent. The industrial oil-containing sewage treatment agent consists of an emulsion breaker, a flocculating agent, a surfactant and a solvent, wherein the mass fraction of each component is as follows: 25 to 35 parts of emulsion breaker, 5 to 10 parts of flocculating agent, 5 to 10 parts of surfactant and 50 to 80 parts of solvent. The industrial oil-containing sewage treatment agent can simultaneously play a role in emulsion breaking, flocculation, bridging and foaming. The composite oil-containing sewage treatment agent is less in consumption, high in oil removal rate and particularly suitable for treating high-concentration oil-containing sewage.

Description

technical field [0001] The invention relates to an industrial oily sewage treatment agent and belongs to the field of water treatment. Background technique [0002] Oily substances contained in oily wastewater include natural petroleum, petroleum products, tar and its fractions, and edible animal and vegetable oils and fats. In terms of pollution to water bodies, it is mainly oil and tar. Due to the great difference in the oil concentration in the wastewater discharged from different industrial sectors, such as the wastewater generated in the oil refining process, the oil content is about 150-1000mg / L, the tar content in the coking wastewater is about 500-800mg / L, and the wastewater discharged from the gas generation station The tar content can reach 2000-3000mg / L. Therefore, the treatment of oily wastewater should first use the grease trap to recover slick oil or heavy oil, the treatment efficiency is 60% to 80%, and the oil content in the effluent is about 100-200mg / L; t...
