Automatic self-cleaning filter with the growing importance of environmental protection, sludge disposal received more and more attention as a social hot spots. But at present, the domestic application of this sludge disposal technology is not yet mature, many technical and conditions there are blind spots, the problem of sludge disposal routes and principles.nylon mesh
Principles: local conditions
Comprehensive consideration of Sludge characteristics, geographic location, environmental conditions and economic and social development level and other factors
For sludge treatment and disposal technology roadmap of the different countries are not the same, there are also differences in different regions of the same country, according to local conditions should be the technical route selection of the basic ideas and principles. Zhang Chen, considering the muddy sludge characteristics, geographic location, environmental conditions and economic and social development level and other factors, local conditions to determine the sludge disposal.
My lack of energy, the need to consume large amounts of energy technology and sludge aerobic stability compared to backwash the filter, anaerobic digestion i s more suitable for China s national conditions and forms of land use. Although sludge drying effect of reduction of the incineration process, and covers an area of small, but its capital investment and operating costs are relatively high, applies only to the major cities, large urban areas of tension in the group as well as land. However, with the economic conditions, the heat value of sludge conditions and scarce land resources, sludge incineration technology is one of the choices.
Second principle: safe, reliable, economic, applicable
Balanced, good pre-planning, to avoid secondary pollution
Zhang Chen, treatment and disposal of sludge from the overall start, take into consideration all aspects of. Must do well in the pre-planning in the field of engineering design, process equipment purchase, and subsequent runs.
From an operating point of view, the best result is a new area, renovation and expansion of urban sewage treatment plant, sludge treatment a nd disposal facilities must be planned and wastewater treatment facilities, while building and put into operation at the same time.
The same time, from the management side, the sludge generation, storage, handling, transport and final disposal of the whole process of development planning and supervision and management. But no matter what kind of technology treatment and disposal of sludge, must follow the technical regulations for sludge treatment and disposal, so "safe, reliable, economic, applied to deal with muddy meet relevant national standards and industry standards and practical measures to prevent secondary pollution.
