Description
Technical field
The utility model relates to the field of sludge treatment of green technology, especially a kind of load TiO
2The device of photoelectrocatalysis advanced treatment mud.
Background technology
Municipal sludge is the residues such as floating foam of sedimentable matters such as the organic matter that produces in the sewage treatment process, microbial bacteria micelle and sewage surface flotation, wherein contains toxic heavy metals such as a large amount of pathogenic bacterias, parasite, pathogenic microorganism 、 dioxin and arsenic, copper, mercury, chromium.Mud granule mainly exists with the form of the outer polymer (EPS) of born of the same parents; Complicated component contains protein (protein), polysaccharide (polysaccarides), soil ulmin (humic-like substances), uronic acid (uronic acid), lipid (1ipid) and DNA etc. usually.Because the water-in-oil structural performance of the outer polymer of mud granule born of the same parents causes the sewage plant sludge water ratio high, volume is big, brings difficulty for stacking and transportation etc.Municipal sludge as arbitrarily throwing aside hill farmland or landfill lack of standardization, will cause new potential threat as dealing with improperly or processing lack of standardization to ecotope.Therefore, the mud that factory produced of further disposing of sewage is the great difficult problem in environmental protection field, the world today.
China is because the sludge treatment dynamics of investment is little for a long time; Cause present domestic sludge treatment to be in serious hysteretic state, pursue wastewater treatment rate that have even unilaterally, simplify as much as possible even ignored the sludge treatment disposal unit; With untreated wet mud arbitrarily transport outward, simple landfill or stacking; Cause many big cities the phenomenon in mud besieged city to occur, and begun to spread, brought totally unfavorable influence to ecotope to small and medium-sized cities.
Along with the acceleration of Urbanization in China, treatment rate of domestic sewage improves year by year, and sludge from wastewater treatment plant output sharply increases greater than 10% speed with annual growth.2010, national town sewage processing rate surpassed 50%, and treatment rate of domestic sewage surpasses 70%, and a year sewage load reaches 36,500,000,000 tons, and a year sludge yield reaches 2,740 ten thousand tons; By 2015, a year sewage treatment capacity reached 47,500,000,000 tons, and a year sludge yield reaches 3,560 ten thousand tons.Sludge treatment has become the major issue of puzzlement China's water treatment field and even environmental area.
