Embodiment 1

[0027] A joint project station oil sludge treatment test

[0028] Site sampling, laboratory testing oil content, PH value and heavy metal content. The results are as follows:

[0029]

[0030] Colwell selected from the species Escherichia library, Helicobacter spp oil, in order to simulate the course of cultivating

[0031] Unfavorable conditions, after 10 days of acclimatization final breed continuously DK-017 strain suitable conditions.

[0032] After the paving site sediment drying oil was added 2.5% and 2% nutrient agents, for rotary, oil sediment twice daily with a rotary tiller.

[0033] Day 10, Day 20, Day 30 were taken for observation field strain in oil sediment samples, the number of DK-017 were measured 4.51 * 10 7 / kg,5.45*10 7 / kg,5.86*10 7 / Kg, does not require supplementary agents.

[0034] Oil sediment before and after treatment in four-point sampling inspection, oil content as follows:

[0035]

Embodiment 2

[0036] Example Two: cesspool factory acidic oil sludge treatment test items

[0037] Site sampling, laboratory testing oil content, PH value and heavy metal content. The results are as follows:

[0038]

[0039] Pylori oil selected from the library spp strain, the above adverse conditions simulated in the course of cultivation, 14 days after the final domesticated breed continuously ZQ-021 strain suitable conditions.

[0040] After the paving site sediment drying oil, 2% and 1% nutrient agents, for rotary, oil sediment twice daily with a rotary tiller.

[0041] Day 10, Day 20, Day 30 were taken for observation field strain in oil sediment samples, the number of DK-017 were measured 2.81 * 10 7 / kg,4.75*10 7 / kg,5.21*10 7 / Kg, a supplementary agents.

[0042] Oil sediment before and after treatment in four-point sampling inspection, oil content as follows:

[0043] 1 2 3 4 Before processing 6.58% 6.12% 5.27% 4.31% 15 days in the middle 1.24% 1.08% 2....

Abstract

The invention provides a construction process for bioremediation of oily sludge. The process steps are as follows: 1) Take oily sludge sand samples, conduct experimental analysis, select matching engineering bacteria, and add acid and alkali contained in oily sludge sand during the cultivation process , heavy metal elements, so that the bacteria that can adapt or mutate survive and become the dominant bacteria; 2) Select nutrients at the same time; Perform mixing, crushing, and maintenance, and control soil PH, EC, soil oxygen content, and humidity through a soil detector; 4) Test the average number of dominant bacteria in the soil every 10 days in the laboratory, according to the activity of the dominant bacteria 5) According to the restoration progress, send the soil oil content to the testing agency about every 15 days; the advantages are: environmental friendliness, no secondary pollution, low treatment price, simple operation, and high treatment efficiency.

Description

Technical field [0001] The present invention relates to a soil environment, and in particular a comprehensive utilization of oily sludge and pollution control processes. Background technique [0002] Oil sediment sediment is a mixture of oil and gas and oil exploration, mining, gathering, waste water (liquid) generated in the process of forming, and use in oil-based muds generated during oil drilling cuttings. According to the characteristics of solid waste oil companies, both production waste sludge, but also a valuable secondary resources. [0003] The current industry standard "onshore oil and gas exploration and utilization of sludge from the oil pollution control requirements" Section 5.2.1 claim oily sludge after the solid phase remaining after treatment of total petroleum hydrocarbons should be less than 2% after treatment the residual solid phase and easy way for laying drifting, bedding wellsite base material. The most commonly used method of oily sludge physicochemical ...
