2) sludge digestion.Sludge digestion namely is the metabolism by microorganism, makes that organic substance resolves into stable material in the mud, removes stink, kills parasitic ovum, and the reduce mud volume is recycled the biogas that produces in the digestive process.
3) sludge dewatering and mummification.Moisture percentage in sewage sludge is the key of restriction sludge disposal and utilization, and after mud dewatered, it was the starting point of landfill and compost that its water ratio is down to 60% from 95%, the 50%th, and the starting point of burning; The mummification link is the key link of ﹠ Mud system power consumption.Sludge drying can make mud significantly subtract appearance, and volume can reduce 4～5 times, and product is stable, odorless and without causal organism.Sludge product purposes after the drying and other treatment is many, can be used as fertilizer, soil improvement agent, substitute energy etc., but is utilized approach self limitation and technology immature and can't mass-producing.
4) sludge incineration.Contain a large amount of organic matters in the mud, has certain calorific value, by burning recyclable sludge energy, treatment process take burning as core is treatment process the most thoroughly, it can make the whole carbonizations of organism, pathogen kill, reduce mud volume is to greatest extent really realized minimizing, the stabilization and innoxious of sludge disposal.Slag after the burning also can become building material, and improvement soil is built the road brick and tile, pottery, concrete fill etc., not only save energy, and protection of the environment.Shortcoming is that the treatment facility investment is large, and processing costs is high, requires incineration temperature to be higher than 850 ℃.If utilize effective external conditions of garbage burning factory, can adopt mud to advance incinerator and carry out multifuel combustion treatment technology nearby.
5) Sludge landfill.The mud sanitary landfill has become a relatively backward Sludge Disposal Techniques at present.The sanitary landfill operation is relatively simple, and investment cost is less, and processing costs is lower, strong adaptability.But appropriation of land is serious, if seepage control technique is inadequate, will cause potential soil and groundwater to pollute.Because the potentially contaminated of its underground water also causes the minimizing etc. of urban land, newly-built landfill yard is resolutely opposed in many countries and regions.
Present stage China's ﹠ Mud main method in, agricultural sludge accounts for 44.8%, the land landfill accounts for 31%, other disposal account for 10.5%, account for 13.7% without disposal.Along with the maturation of sludge disposal technology and the raising of environmental requirement, landfill is more and more restricted, agricultural scope also is subjected to the constraint of relevant laws and regulations gradually, country encourages standard compliant mud to carry out the soil utilization, proposition is concentrated at mud, conditioning and dehydration etc. realize on the conventional treatment process basis of sludge reduction, encourage to adopt the coupling mode of anhydration and incineration, improve the utilization efficiency of heat energy of mud; Encourage sludge incineration factory and garbage burning factory to build jointly, so the total trend of sludge treatment is to burning future development.
