Background

At present, most sewage treatment plants simplify as much as possible in order to save capital, even neglect sludge treatment and disposal, leave the established sludge treatment facilities unused for a long time in order to save operating cost, and even transport wet sludge which is not treated at all, simply fill or stack the wet sludge, so that a plurality of large cities have sludge enclosing phenomena and begin to spread to medium and small cities, and great risks and potential safety hazards are brought to ecological environment. Mainly expressed in the following main aspects: low sludge treatment rate, imperfect process, laggard sludge treatment technical equipment, low sludge treatment management level, low sludge treatment design level and low sludge treatment investment. The disposal of the sludge is increasingly a problem, and the method has important significance for ensuring the good operation of a sewage treatment plant, preventing the generation of new secondary pollution and protecting the environment.

The waste branches are burnt to pollute air, are easy to cause fire after being placed, become hotbeds for various insects after being rotten for a long time, are smelly and can pollute water sources. Plant residues and straws of crops such as vegetables and vegetables planted by farmers can generate more than 17 million tons of waste every year, excrement sewage generated by breeding livestock and poultry is more than 60 million tons, waste gas branches are added, the waste materials generated by agricultural production pollute soil and endanger water environment, and if the agricultural wastes are not innovated and treated in time, the agricultural wastes can cause the problems of smoke, pollution, blockage and toxicity, dirty, messy, poor and dangerous environment and the like. At present, the garbage is treated by mainly using a landfill method in China, but the garbage treatment method has the problems of wide occupied area, resource waste and pollution.
