Description
Technical field
The present invention relates to oily waste water biologic treating technique field more particularly to a kind of microbiological treatment sides of oily waste water
Method and processor.
Background technique
With the development of industry, the usage amount of oil product is increasing, but not due to the lagging in development of various technologies and management
Reasons perfect etc. to the greatest extent make a large amount of oil products enter water body, form pollution.The source of oily waste water is very wide, in adopting for petroleum industry
A large amount of oily waste waters can be all generated in oil, oil refining, store oil, transportational process and the production process of petro chemical industry.Oily waste water
Pollution be mainly manifested in the following aspects: (1) influence drinking water sources and groundwater resources, endanger aquatic resources；(2) it endangers
Evil human health；(3) atmosphere is polluted；(4) production estimation is influenced；(5) natural landscape, or even it is also possible to because coalescence are destroyed
Oil product burning and generate safety problem.In view of the pollution of oily waste water, China's regulation oily waste water highest allows to discharge dense
Degree is 10mg/L.Therefore oily waste water improvement is current field of environment engineering urgent problem.
For at present, the method for oil removing mainly has chemical method, physical method, biological method, compared with first two processing side
Method, bioanalysis is less toxic, without secondary pollution with it, cleans and becomes research emphasis.Microalgae, a master as microorganism treatment
Want part, it is widely distributed, small in size, the procreation period is short, the speed of growth is fast.Therefore, select chlorella vulgaris as oily waste water
The filling liquid of processing unit.Chlorella vulgaris, as can heterotrophic microalgae, the metabolism that hydrocarbons carry out itself can be efficiently used
Activity makes it be degraded to CO2 and H2O, to carry out depth degradation to oily waste water.
For example, application No. is CN201410058175.8 in Chinese patent literature, publication date is open on June 4th, 2014
Entitled " a kind of bioremediation and equipment of oil extraction-generated waste water " patent of invention, this application discloses a kind of oil extraction-generated waste waters
Biological treatment, including air-dissolving air-float, the oil removing of microorganism grease removal tank, biological aerated filter filtering, sinterable polymer filter core
Filter filters four steps: 1, water enters dissolved air flotation device, removes most of crude oil and suspended matter；2, step 1 go out
Water enters microorganism oil removing unit removal crude oil；3, the water outlet of step 2 is promoted to biological aerated filter, and remaining crude oil exists in water
It degrades under the action of microorganism, while removing most suspended substances；4, it is fine to be promoted to sinterable polymer filter core for the water outlet of step 3
Filter element, further removes the suspended matter in water removal, and water outlet reaches " oil content≤1mg/L, suspended matter≤1mg/L, median particle size
≤1μm".Disadvantage is that: 1, need to be aerated 20-24 hours for restoring the activity of microbial flora, it is subsequent in order to drop
Low aeration rate will also continue bored aeration 40 to 48 hours, long the time required to oil removal process, inefficient；2, oily waste water was aerated
Journey, fluid is almost static, and gas exchanges are slow, and the wastewater treatment speed positioned at the corner of biological aerated filter falls behind other positions
Waste water needs to increase aeration time to handle the waste water in corner, and waste of resource reduces purification efficiency.
Therefore a kind of design method of the microbiological treatment device of oily waste water is designed to improve oily waste water in oil removal process
In transmission efficiency and mixing rate, improve oily waste water degradation rate just it is necessary to.
Summary of the invention
