초록 ▼

An apparatus and method for removing unwanted substances from media such as water and soil. Various industrial waste water streams can be treated simply and effectively to remove therefrom such unwanted substances as petroleum hydrocarbons, heavy metals, phenolics, salt, ethylene glycol, and strontium, and sea water can be similarly treated to remove salt as well as petroleum hydrocarbons therefrom. Waste water or sea water is contacted with zeolite in the presence of a surfactant, and optionally hydrophobic cellulose, to effect removal of the unwanted substances therefrom; and soil contaminated with petroleum hydrocarbons, salt or agricultural chemicals can be rejuvenated by mixing the soil with zeolite and a surfactant followed by washing. The apparatus and method provides simultaneous removal of a wide variety of unwanted substances from a feed stream passed therethrough, in contrast to prior art procedures effective to remove only one such substance per treatment. The method is further effective to suppress the formation of foul smelling gas in standing water containing petroleum hydrocarbons and one or more substances tending to promote such gas formation.

대표청구항 ▼

A method of treating motor vehicle washing waste water containing at least one of an oil and grease constituent and a nonsurfactant petroleum hydrocarbon-diesel constituent, said method being capable of removing from said waste water substantially 100 percent of at least one of said constituents, said method comprising the step of bringing said waste water into direct contact with the surfaces of a quantity of pebbles of natural zeolite exposed within a tank for said contact, said contact taking place in the presence of a surfactant, wherein said waste water further contains one or more of heavy metals, phenolics, dissolved sulfides, ethylene glycol, barium, strontium, boron, calcium, and sodium, at least one of which is also removed by said step.
