Abstract

The invention discloses an oil field sewage treatment agent, which comprises aluminum sulfate, sodium polyacrylate, tea saponin crystal, hydroxylated lecithin, disodium ethylene diamine tetraacetate,sodium malate, sodium chloride, grapefruit peel powder, guar gum, sodium dodecyl sulfate, and diazolidinyl urea. The oil field sewage treatment agent is less in consumption and high in oil removal rate, and has a quite obvious water purification effect. The treated water reaches the integrated water discharge standard and is re-injected to the ground, so that the environmental pollution is reduced. Toxicity of the raw materials is small, secondary pollution is prevented, and the oil field sewage treatment agent is eco-friendly.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to an oilfield sewage treatment agent and a preparation method thereof. Background technique [0002] Oily wastewater mainly comes from petroleum, petrochemical, steel, coking, gas generation stations, mechanical processing and other industrial sectors. The relative density of oil pollutants in wastewater is less than 1 except heavy tar whose relative density is above 1.1. Oily wastewater has adverse effects on humans, animals and plants, and even the entire ecosystem. [0003] At present, for the treatment of oily wastewater, some manufacturers inject it into the grease trap, and the oil droplets with a density lower than water will rise to the water surface, and the particles and impurities larger than water will sink to the bottom of the tank. However, for oil droplets and suspended solids that cannot be separated by gravity settling, they cannot be separated according to this method...
