Description
Technical field
The present invention relates to technical field of sludge treatment, more specifically to sludge organism treatment system.
Background technology
Wastewater Treated by Activated Sludge Process sewage, as a kind of biological treatment process, is widely used in municipal wastewater treatment plant and industrial sewage factory.In recent years, municipal wastewater treatment plant quantity constantly increases, and the excess sludge production produced in Wastewater Treated by Activated Sludge Process sewage process increases thereupon rapidly, only within 2010 1 year, just creates the dewatered sludge more than 600 ten thousand tons.Mud can not get effectively processing and can cause a series of environmental problem with disposal, and China's sludge disposal is also in seriously delayed state.
Anaerobic digestion techniques is the most frequently used a kind of technique of current China major part sewage work lignin-sludge, mud is through anaerobic digestion, produce bioenergy (biogas), (biogas can be used for generating so not only to produce certain economic benefit, be converted into high-quality gas), and the biologically stable of mud can be improved, and cut down mud to the pollution load of environment, relative with recycling favourable to disposing after mud.In a word, can utilize and the angle analysis of protection of the environment from sludge organism, anaerobic digestion is a kind of technology of Sustainable development, is also a kind of sludge treatment approach of comparatively economical rationality.But the C/N comparison digestive process in response matrix has considerable influence.The C/N value that it is generally acknowledged digestion raw material is 20: 1 ~ 30: 1 comparatively suitable.
But the C/N value of mud is lower, generally all below 5: 1, reaction system nitrogen content is too high, causes anaerobic digestion gas production amount low.Mud is mixed carry out anaerobically fermenting with agricultural crop straw (C/N value is 50: 1), adjustable anaerobic digestion raw material C/N.But; Mierocrystalline cellulose contained by stalk is hardly degraded organic substance; simultaneously in mud cell walls Cell protection from osmotic lysis; cause stalk and mud mixing anaerobic to digest and need longer hydraulic detention time; which results in sludge digestion structures bulky, add construction and operation cost.
Low-kappa number is a kind of means of effective promotion anaerobic digestion, cracks effect mainly to cell walls, shows that digestion time shortens, and gas production rate increases.General pretreatment process has: chemical oxidation (ozone oxidation etc.), physical method (pyrolysis etc.) etc.But these treatment processs often need additional certain material, and can produce the pollution of certain procedures, consume some energy.
