   In 2011, in Guanzhong part of weihe basin, sludge amount used for  sanitary landfill in 55 town sewage disposal plants reaches to 189563t, the amount of sludge land use was about 226694t. The main reason why sludge used for land use is more than sludge used for sanitary landfill is that sewage disposal plants which produce large amount of sludge Xianyang and xi’an mainly use sludge for land use. Land use amount of Xi'an urban sewage treatment plant accounts for 73.6% of the total amount of Weihe River in Guanzhong 55 sewage town treatment plants. Land use amount in Xianyang city urban sewage treatment plants accounts for about25.2% of the total  amount of land utilization of sewage sludge accounted for Weihe River in Guanzhong 55 urban sewage treatment factories. Land use in Baoji City urban sewage treatment plant accounted for about 1.2% of total in Weihe River in Guanzhong 55 urban sewage treatment factory land use amount.
Government’s responsibilities in strengthening sludge disposal
   Most of the urban sewage treatment plants think that the sludge treatment and disposal should be the responsibility of the local government, but because most local governments are lacking financial supports in sewage treatment field, so they are too busy to take measures for sludge disposal in urban sewage treatment plants, which results in many worrying situations in Guanzhong region of the Weihe River basin of urban sewage treatment sludge treatment and disposal .This situation which is caused by lack of money is mainly the lack of responsibilities of local government.
Sludge stabilization treatment measures need to be strengthened
    About half (52.37%) of 55 urban town sewage disposal plants in guanzhong part of weihe basin hasn’t adopted sludge stabilization measures. Because sludge without stabilized treatment is discharged into the environment is likely to cause the secondary pollution to water, soil and atmosphere. At the same time, it will cause but also cause difficulties to fulfill subsequent sludge disposal objectives and resources goal. Therefore, powerful measures must be adopted to sewage disposal plants in weihe basin which hasn’t got stable disposal.
Perfect sludge disposal plans
    Shaanxi province urban sewage treatment and recycling facilities in the construction of 12^th five year planning” not only provides principles, objectives, approaches and methods of sludge treatment and disposal of urban sewage treatment plants in Shaanxi province were put forward. It also requires that all sludge must be stabilized treatment. After stable disposal, sludge must regard landfill as prior disposal method.
Strengthen the supervision of the sludge disposal measures and perfect binding forces
    Guanzhong part of Weihe River Basin in the middle of town sewage treatment plant sewage treatment has relatively sound regulatory measures and constraint index. However, in sludge treatment and disposal aspects, it is lack of corresponding supervision measures and constraints of strong control index, which leads to many loopholes in the sludge treatment and disposal. The occurrence of secondary pollution caused by inappropriate sludge treatment caused by improper disposal measures increases dramatically, so we must adjust measures to local conditions to formulate a more sound sludge treatment and disposal of regulatory measures and binding targets in order to promote the Guanzhong region of the Weihe River Basin of urban sewage treatment plant sludge treatment of the benign development of the cause of disposal.
Increase water intake supervision
    At present, the process of sludge disposal of guanzhong part of Weihe River Basin has the biggest impact. most severe problem is that heavy metal diversification and content in sludge exceed the standard, which is led by lack of supervision and loopholes. Basic methods to solve these problems reply on scientific planning, adjusting water intake proportion between domestic sludge and industrial waste water and strengthen supervision on water pre treatment.
Increase sludge resources utilization way
    Town sewage treatment plants of guanzhong part of weihe basin realize reclamation aim through sludge processing (earthworm breeding, natural dry and sludge aerobic fermentation processing technology). After that, sludge will be used for land. However, because there are some main obstacles existing in land use, such as varieties of heavy metal content and high heavy metal content, many limits on land use are resulted. After summing up the domestic and foreign present situation of sludge disposal, we can find that sludge can also be applied in building materials, cement products, sludge fiberboard and sludge activated carbon. The application fields have low requests for content of heavy metals. In order to increase economic benefits, reduce secondary pollution caused by sludge and security hidden danger of land use, new application ways for sludge reclamation must be increased according to the local actual situation of research and development for the sludge resources of the new technology. 

：Under the situation of Sludge pollution of ＂12th Five-Year＂ , what can you do? Sludge treatment ：Should our country advocate land utilization of sludge?
