Mud precipitation concentration；It is herein that one kind effectively removes removal organic polluter and just its ore deposit using Anaerobic Treatment
The method of change, organic compound is changed into methane and carbon dioxide by it.Anaerobic reaction typically quilt
It is summarised as three phases, i.e. hydrolysis acidification stage, hydrogenesis and acetogenesis stage, methane phase stage.
Have running cost low using Anaerobic Methods in Treating, it is adaptable at the sewage of various different scales
Reason, sludge yield is small, the characteristics of low to nutrient requirement.But from microorganism and chemical terms
From the point of view of, Anaerobic Treatment merely provides a kind of pretreatment, it generally require that post-processing to remove out
Remaining organic matter in water.
Unpowered anaerobic pond is the main body structures of the sewage treatment project.Due to being hung in pond
Beneficial to the filler of attached growth of microorganisms, thus it is greatly improved COD (COD or CODcr is
Refer to COD and refer to that under conditions of necessarily strictly the reducing substances in water is additional
In the presence of strong oxidizer, the quantity that oxidant is consumed when decomposing is oxidized, with the mg/L of oxygen
Represent.COD reflects the degree polluted in water by reducing substances, these material bags
Include inorganic in organic matter, nitrite, ferrous salt, sulfide etc., but general water and waste water go back
The quantity of immunogenic substance is relatively little, and by Organic Pollution be it is very universal, therefore, COD
Can as organic substance relative amount a composite target.) clearance, higher than general
Without the anaerobic digester as hanging filler, civilwork engineering quantity is reduced.
In the anaerobic pond for having added filler, the reservation of anaerobic sludge is completed by two ways：One
It is that bacterium forms biomembrane on fixed filler surface；Two be to form bacterium in reaction compartment to gather
Collective.Accumulation of the high concentration anaerobic sludge in reaction tank is that anaerobic pond has highly effective reaction performance
Basic of Biology, under certain sludge specific methanogenic activity, the load of anaerobic reactor with
