Description

Biological purification of waste water is removed the method for ethylene glycol
The present invention relates to biological purification of waste water, remove contained high density ethylene glycol.
The present invention is used to exploit and process the factory of sulfur-containing gas, in its technological process, make spent glycol and generate the ethylene glycol sewage of concentration greater than 2000 mg/litre.
In gas plant, be the aqueous glycol solution of dry natural gas working concentration 70-80%.The ethylene glycol saturated solution through rectifying, concentrate and return production cycle and can regenerate.The sewage that is generated when regeneration contains ethylene glycol (in most cases dense, as to reach 2000 mg/litre and Geng Duo) and trace element (K +, M 2+ g, Z 2+ n, F 2+ e, M 2+ n, C 2+ a, N - O2, SO 2- 4).
Now, to containing the sewage of high density ethylene glycol, perhaps just be embedded in underground absorption region without giving purification, the face of land and underground water are polluted, perhaps sewage is sent into stove,, will make topsoil like this with organism contained in the burning-off sewage.
Known, concentration is that the ethylene glycol of 0.1 mg/litre (is seen Kuniska Goldfinger Wladyslava with phenol as Institute of Micro-biology's digestion that carbon source is activated mud, Wlostowski Tadeusz " Application of semicontinuous culture on membrane filters for the study of activated sludge bacteria " Acta microbiol pol., 1980,29, No.4,407-412)
Content can (be seen Watson G.K with Acinetobacter (Acineto-bacter) quasi-microorganism less than the ethylene glycol of 10 mg/litre, Iones N.The biodegradation of polyethylene glycols by sewage bacteria " Water Res " 1977, II, N.I.95-100) and Rhodopseudomonas (Pseudomonas) quasi-microorganism (see Fincher E.L.and Payne W.T.Bacterial utilisation of e-ther glycols " Appl microbiol ", 1962,10, P542-547) destroy.
Yet it is impossible that mentioned microorganism is used for Industrial cleaning facility sewage, because they can not destroy high density ethylene glycol.
In the biological purification of waste water, the method of removing the Tributyl phosphate ester is known, specifically be to use active sludge simultaneously in the sewage adding ethylene glycol make concentration reach 200 mg/litre, ethylene glycol is the co-oxidants of the main dirt of sewage in this method, be the carbon source of active sludge microorganism simultaneously, thereby self also destroyed (see Soviet Union inventor certificate № .673616,1979.7.15 is open, classification number CO2C5/10).
The shortcoming of currently known methods is to guarantee to destroy high density ethylene glycol (being higher than 200 mg/litre), and therefore death can not purify because the active sludge of biopurification facility cannot stand the pollutent of such high density.Another shortcoming of this method is that dirt biological chemistry destructive process efficient is not high, and its reason is that active sludge given adaptation time oversize (three time-of-weeks).
The purpose of this invention is to provide a kind of method that contains high density (being higher than 2000 mg/litre) ethylene glycol sewage that purifies with biological approach.
Proposing on basis of the present invention of task is: a kind of method of biological purification of waste water is provided, uses to have the microorganism of destroying high density ethylene glycol (being higher than 2000 mg/litre) characteristic in this method.
Proposing of task solves as follows: according to the present invention, remove in the method for ethylene glycol at biological purification of waste water, in the sewage that contains ethylene glycol, trace element, add phosphorus, nitrogenous source and Arthrobacter (Arthrobacter) quasi-microorganism, then mentioned microorganism is cultivated down at 20-35 ℃, up to from said sewage, removing ethylene glycol.
Because the application's invention just might contain the sewage that ethylene glycol is higher than 2000 mg/litre with the biological method purification, degree of purification reaches 99%.
Invention according to the application, use the pure bacterium 667(Arthro-bacter of bacterial strain Arthrobacter simplex 667), Arthrobacter change bacterium 667(Arthro-bacter variabilis 667) be suitable as Arthrobacter (Arthroba-cter) quasi-microorganism, they are deposited with industrial microorganism heredity of full Soviet Union and breeding scientific research industrial microorganism central authorities exhibition hall, perhaps use bacterial strain Arthrobacter bacterial classification 126(Arthrobacter species 126), Arthrobacter 127(Ar-throbacter 127), they are to be deposited with academy of sciences of Ukraine republic A.B. Du Mansiji colloid chemistry and water chemistry institute microorganism-destruction bacterium exhibition hall.
For purification contains the sewage that concentration is higher than 4000 mg/litre ethylene glycol, according to the present invention, the adding diethanolamine is suitable as the co-oxidants of nitrogenous source and ethylene glycol in sewage, diethanolamine is 1 with the ratio of ethylene glycol: 4-5, correspondingly, also add Rhodopseudomonas (Pseudomonas) quasi-microorganism in addition.
For purification contains the sewage of ethylene glycol and diethanolamine, according to the application's invention, keeping the ratio of diethanolamine and ethylene glycol in the process of purifying waste water is 1: 4-5 is suitable.
To biological purification of waste water of the present invention, remove the method for ethylene glycol and the detailed description of embodiment by following, other purpose of the present invention and advantage can be clearer.
In the application's invention, use new Arthrobacter (Arthrobacter) bacterioid, it has the ability of strong destruction high density (2000 mg/litre or higher) ethylene glycol, and making ethylene glycol content last in the sewage is the 70-100 mg/litre.
