Description
Technical field
The invention belongs to environment protection and Persistent organic pollutants processing technology field, relate to a kind of method promoting oestrogenic hormon nonyl phenol anaerobic degradation in mud.
Background technology
Nonyl phenol is mainly derived from the degraded of polyoxyethylene nonylphenol ether, and polyoxyethylene nonylphenol ether is synthetic detergent main raw material, and application widely.Usually, along with discharge and the process of waste water, polyoxyethylene nonylphenol ether is converted into the stronger nonyl phenol of toxicity, and is enriched in mud in a large number, and produces harm to follow-up specific resistance to filtration and recycling.
The aspect such as cultivation of the research of relevant the NP both at home and abroad mainly Transport And Transformation of concentrated NP in the environment, microbiological deterioration, biological adsorption, dominant bacteria.The microbiological deterioration degree of NP and external environmental condition as closely related in oxygen concn, temperature, nutritive substance interpolation etc., and different strain also has larger difference to the degradation mechanism of NP and pathways metabolism.Recent NP has been proved and under the anaerobic condition such as sulfate reduction, methane phase, biological degradation can have occurred.
Although nonyl phenol (NP) has been proved to be able under anaerobic biological degradation occur in mud, but still the research that these materials in shortage mud are degraded under fermentation and acid condition, and sludge anaerobic fermentation is the important channel that mud carries out following resource utilization.Alkaline fermentation effectively can destroy the structure of mud flco and extracellular polymeric (EPS), be conducive to nonyl phenol from Sludge Surface desorption, improve its movability and the solubleness in aqueous phase, thus increase the chance that contacts with pollutent of microorganism, promotion organic pollutant can bioavailability.As can be seen here, it is very necessary for building the degradation method of nonyl phenol in mud alkalescence fermenting process in a kind of mud.
Summary of the invention
The object of the present invention is to provide a kind of method utilizing tensio-active agent and alkaline purification acting in conjunction to promote oestrogenic hormon nonyl phenol anaerobic degradation in mud.
For achieving the above object, the present invention is by the following technical solutions:
Utilize tensio-active agent and alkaline purification acting in conjunction to promote a method for oestrogenic hormon nonyl phenol anaerobic degradation in mud, comprise the following steps:
Add in anaerobic reactor by the mud containing nonyl phenol, control to ferment pH value in anaerobic reactor for alkalescence, and add tensio-active agent, stir and material is mixed, control leavening temperature is 20 ~ 55 DEG C simultaneously; Reaction times is 7 ~ 11 days, it is 8.0 ~ 11.0 that control ph controls, tensio-active agent is any one in polyoxyethylene laurel ether, Brij-35, Sodium dodecylbenzene sulfonate or alkyl carboxyl sodium sulfonate, and the dosage of tensio-active agent is 0.1 ~ 100g/kgTSS.
In the present invention, control ph is 8.0 ~ 10.0.
In the present invention, leavening temperature is 37 ~ 55 DEG C.
In the present invention, the dosage of described tensio-active agent is 0.50 ~ 10 g/kg TSS.
In the present invention, in mud, the content of NP is 80 ~ 300mg/kg dewatered sludge.
Under normal circumstances, the increase of anaerobic reactor working time can improve degradation effect, and also can increase running cost, the minimizing of working time then can reduce degradation effect simultaneously, and amid all these factors, the working time selecting anaerobic reactor is 9 days in the present invention.
Sludge anaerobic fermentation is as follows to the degraded ultimate principle of nonyl phenol in mud to utilize alkaline purification to promote in the present invention:
Nonyl phenol major reason of difficult degradation in anaerobic sludge digestion process is water-soluble very low, and lipotropy is comparatively strong, is very easily adsorbed on Sludge Surface, causes bioavailability poor.Therefore, by nonyl phenol from sludge system desorption, migration enters aqueous phase and improves its solubleness in aqueous phase is improve the effective way of nonyl phenol bioavailability and degradation rate.
Mud granule surface is with negative charge, under alkaline fermentation condition, particularly when the pH value of mud raises, mud granule cell surface with negative charge also gradually raise thus produce high electrostatic repulsion, destroy the tight flocculation structure of mud, thus add the touch opportunity being adsorbed on nonyl phenol in Sludge Surface and microorganism, what promote the nonyl phenol in sludge anaerobic fermentation system can bioavailability.
In addition, the concentration that alkaline purification also can increase organic substrates in sludge fermentation system supplies microorganism as primary energy material, is conducive to forming Co metabolism effect with nonyl phenol.The interpolation of tensio-active agent is then conducive to the solute effect of nonyl phenol in fermentation liquid phase improving desorb further, promotes that nonyl phenol is at the degradation efficiency of sludge anaerobic digestion system.
The effect efficiency that advantage of the present invention and practice produce comprises:
1., in mud alkalescence fermenting process, greatly facilitate the degradation effect of nonyl phenol in mud;
2. the removal of nonyl phenol in mud, is conducive to follow-up recycling sludge and utilizes.
