Problems solved by technology

Obviously, physical methods are simple and crude, and local burial and centralized stacking cannot fundamentally deal with pollution, and the hidden dangers are the greatest; chemical methods are likely to cause secondary pollution, and incineration will produce smoke and toxic and harmful gases into the air. If people inhale the air Harmful substances will have a direct impact on people's health, and the cost of chemical decomposition is high, especially when the pollutants are scattered and difficult to collect

Embodiment Construction

[0026] Implementation column 1

[0027] Today there are 100 cubic meters of oily sludge with an oil content of 6%. The first step is to remove solid waste with a volume of more than 10 cubic centimeters such as stones and asphalt blocks in the oily sludge, and spread the oily sludge on a site of about 250 square meters with a thickness of 40 cm. The surface of the site is concrete anti-seepage Repeated rotary tillage with a rotary tiller, and at the same time add 0.3% crude oil decoagulant by sludge weight until it is fully mixed with the soil. Take a typical oily sludge sample at a land temperature of 25°C, and select effective strains with a degradation efficiency of more than 30% through directional screening. After multiplication and adsorption with wheat bran, a solid bacterial agent with a moisture content of 10% is prepared for the next step. Pseudomonas aeruginosa of the genus Pseudomonas, Micrococcus luteus of the genus Micrococcus, Bacillus subtilis of the genus Bac...

Abstract

The invention discloses a harmless biological comprehensive treatment method for oily sludge. The method includes the following steps that (1), a crude oil deflocculation agent is added to deflocculate crude oil; (2), an auxiliary material is added for anaerobic compost; (3), microbial fungicide is added for aerobic fermentation; (4), plant auxiliary degradation is performed; the microbial fungicide comprises pseudomonas pseudomonas aeruginosa, micrococcus genera micrococcus luteus, bacillus bacillus subtilis, acinetobacter acinetobacter junii and acetobacter acetobacter aceti with the weight percentage being 1: 1.5: 1: 1.6: 2. The harmless biological comprehensive treatment method for the oily sludge aims to achieve the purposes of being economic, environmentally friendly and efficient.

Description

technical field [0001] The invention relates to the technical field of oil pollution treatment, in particular to a harmless biological comprehensive treatment method for oily sludge. Background technique [0002] According to statistics, about 8 million tons of petroleum pollutants enter the environment every year in the world. In my country, this figure is also showing an upward trend year by year. Statistics show that after an oil well operation is completed, about 1 ton of oil may be left within a radius of 1000-2000m. It is especially serious near the wellhead. There are also crude oil spills caused by man-made or other external factors, which will also cause oil pollutants to enter the environment. With the erosion of rainwater and surface runoff, and even human production activities, this pollution will continue to spread and migrate to depth and breadth for a long period of time. Once the soil is contaminated by oil, if it is not treated in time, it will have a pr...
