Embodiment 1

[0018] Sodium stearate 306mg, add 18g of water, heat to 90°C, all the solutes are dissolved, vortex or stir, slowly cool down, when it reaches about 70°C, it suddenly solidifies, and then the best and longest fiber is formed. Microscopic pictures of fibers (e.g. figure 1 Shown).

Embodiment 2

[0020] Sodium stearate 306mg, sodium chloride 0.6g, water 18g, heated to 100°C, all the solutes are dissolved, vortex mixing or stirring, slowly cooling down, when it reaches about 70°C, it suddenly solidifies and forms the best and longest fiber. This fiber is stronger than the product of Example 1 under the microscope. Microscopic pictures of fibers (e.g. figure 1 Shown).

Embodiment 3

[0022] In the product of Example 1, benzene was gradually added while shaking, and the added benzene gradually formed an affordable sphere, and the final added amount reached 2.59 g, and the precipitated water was slightly turbid. In the product of Example 2, benzene was gradually added and shaken at the same time. The added benzene gradually formed an affordable sphere. The final addition amount reached 3.06g, and the precipitated water was clear and transparent (such as figure 2 Shown).

Abstract

The invention discloses a treatment method for industrial oily waste water, sea spilled oil reclaiming, waste oil in home and food manufacturing with sodium stearate. Adds some water or weak salt water to sodium stearate, heats them and stirs them and cools them to 70 deg.C, then they are frozen, and produces the sodium stearate fiber; Then adds in oil material, stirs them and makes the water oil into solid. The invention has no secondary contamination to environment.

Description

Technical field [0001] The present invention belongs to the technical scope of oil and fat treatment, and particularly relates to solidification treatment of large amounts of waste oil brought by industrial oily wastewater, marine oil spill recovery, and household and food manufacturing by using sodium stearate to solidify and treat oily waste water, marine oil spills and Edible waste oil method. technical background [0002] The petroleum industry has a history of decades of development. The petroleum industry has enriched lives, and at the same time has become the biggest cause of environmental pollution. Among them, the discharge of oil production wastewater and the recovery of marine oil spills have become hot topics in environmental protection. [0003] my country’s oilfields are widely distributed, and all oilfields have basically adopted water injection development methods. Although part of the effluent is reinjected, the amount of sewage discharged is still considerable. ...
