Description
Technical field
The present invention relates to chemical industry and environmental technology field, particularly relate to a kind of for mud, particularly the method for design of urban wastewater treatment firm sludge treatment equipment and device technique field thereof.
Background technology
In recent years, along with the quick raising of wastewater treatment in China ability, sludge quantity also synchronously significantly increases.By in by the end of March, 2013, only with regard to urban wastewater treatment firm mud, whole nation the planned city, county add up to build up urban wastewater treatment firm 3451, sewage treatment capacity about 1.45 billion cubic meters/day, year produces more than 3,500 ten thousand tons, the mud of water content 80%, and increases progressively with the sewage work of about 120 every year.According to statistics, about 80% Sewage Plant has the thickening facility of mud, reaches minimizing to a certain degree.But about there is the mud of 80% without stabilization treatment, land is transferred to containing pollutents such as repugnant substance, pathogenic agent, persistent organisms from sewage in mud, cause pollutent to spread further, the environment building up the sewage treatment facility put into operation is had a greatly reduced quality with reduction of discharging benefit.36 the key cities' specific resistance to filtration rates in the whole nation reach 80%, and other the planned cities reach 70%, and county town and emphasis town reach 30%.And China's urban wastewater treatment firm mud has that floor space is large, water pollution, soil pollution, bacteria breed, topsoil etc. five endanger greatly.And in current disposal options, landfill accounts for 63.0%, sludge aerobic fermentation+agricultural accounts for 13.5%, mud nature mummification comprehensive utilization accounts for 5.4%, sludge incineration accounts for 1.8%, mud air storage and outward transport respectively account for 1.8% and 14.4%.In fact, the mud overwhelming majority of landfill, air storage and outward transport belongs to random disposal, and the ratio really realizing safe disposal is no more than 20%, and sludge treatment situation is very severe.To account for the burning disposal of sludge treatment total amount 1.8%, good treatment process is calculated with regard to sludge incineration in current method for sludge treatment, sludge incineration process is: after being mixed by a certain percentage with appropriate coal-fired coal dust by the mud of water ratio 80%, through granulation, be be delivered in incinerator after preliminary drying in the drying installation of 400 DEG C to burn completely at interior cavity temperature, lime-ash is discharged from bottom.The three wastes that the process of this burning produces still continue to produce secondary pollution again, not only do not handle well, also need supplementary external fuel on the contrary, the source of pollution that the dust, dioxin produced in burning process etc. are new, will cause new pollution to air and environment.And restrict a lot of because have of specific resistance to filtration Facilities Construction at present, but national specific resistance to filtration general technical route is not clearly one of important restriction factor.For improving China's specific resistance to filtration state of the art further, conscientiously the requirement of sewage sludge harmlessness, minimizing, stabilization, resource utilization is reached, avoid the secondary pollution caused thus, alleviate sludge yield and the delayed contradiction of sludge treatment ability, China has put into effect a series of policy, planning in recent years.Its Chinese Home to be combined by house and town and country construction portion, Environmental Protection Department, the Department of Science and Technology in 2009 and has been issued " urban wastewater treatment firm specific resistance to filtration and pollution prevention technique policy (trying) "; Within 2011, house town and country construction portion, National Development and Reform Commission organize in concert and have worked out " urban wastewater treatment firm specific resistance to filtration technical manual (trying) "; Execution plays " urban drainage and sewage disposal regulations " on January 1st, 2014 in country, within 2014, " 65 " China's World Environment Day themes as " declaring a war to pollution ", and to the main direction that pollution is declared a war be: in-depth prevention and control of air pollution, fortified water prevention and cure of pollution, do a good job of it remediation contaminated soil, strengthen heavy metal, chemical and Hazardous Wastes Management and prevent and treat dynamics, in-depth industrial pollution control.As can be seen here, China has a high potential on specific resistance to filtration, and Rapid development stage is stepped in specific resistance to filtration market.Therefore, seek a kind of newly, reliably, the method for design of the sludge treatment equipment of non-secondary pollution, safety and environmental protection and device thereof be for those skilled in the art of the present technique being really a technical task urgent and urgently to be resolved hurrily.
