    With the development of sludge disposal in Meizhou city, the daily production amount of sludge is getting increased. There are several ways to dispose sludge in Meizhou city.
     1. Basic situation of sludge disposal in Meizhou city
At present, Meizhou city has built eight sewage treatment plant, the city's sewage treatment capacity of 17 million tons. Daily sludge production increased dramatically, up to more than 15 tons of 2010 produced a total of tons of sludge 4069.91, 2011 is generated sludge 5591.44 tons, in 2012 sludge generated a total of 5703 tons, assumes the trend of escalation. The sewage treatment plant sludge after dehydration, the moisture content was generally higher, about is about 80%, by special vehicles shipped landfill landfill disposal.
     2. Problems exist in landfill disposal methods
Take urban sewage treatment plant sludge landfill disposal method has some deficiencies, not only takes up a lot of land, but also may cause serious secondary pollution (stench and harmful pathogens). One is that the landfill or open dumps the sludge anaerobic fermentation to produce large amounts of methane, ammonia and hydrogen sulfide odor source material, causing odor, pollution of the air; in a dry climate is also very easy to spread harmful pathogenic bacteria; the second is due to the urban sludge moisture content high, in the landfill field difficult to compaction to landfill bring security risks; the third is that do not meet the resource reduction, harmless, no comprehensive utilization
    3. Sludge disposal methods which are suitable for Meizhou city
The sludge treatment disposal follow the principle of "safety, environmental protection, recycling, saving energy and reducing consumption, adjust measures to local conditions, safe and reliable", which recycling is an important goal of sludge treatment and disposal should strive to achieve conditions is sludge treatment and disposal scheme required decision the basic premise, considering the characteristics of sewage sludge and the change in the future, land and characteristics of local resources, the availability of cement and thermal power plant and other industrial furnace condition, the factors of economic and social development, to determine in the region of the sludge treatment and disposal technology route and scheme. Combining the advantages of the cement industry in Meizhou area developed, may give priority to the use of cement kiln co disposal of sludge. The use of building materials disposal.
    4. Lessons got from sludge disposal
A. Make overall arrangements and plans
For the realization of the sewage treatment plant sludge reduction, stabilization, harmless treatment goals, given in Meizhou city sludge disposal status of, an urgent need to speed up construction of urban sewage treatment plant sludge harmless facilities, the city sludge disposal will be included in the "1025" planning of environmental protection, "second five" pollution reduction and environmental responsibility assessment, formulate relevant supporting policies, to co-ordinate arrangements for the relevant special funds, to speed up the sludge treatment and disposal project construction, sludge standardized disposal.
B. Policy support and standardization
    All along, the cement industry is a traditional industry in Meizhou City, is also the pillar industry. According to the development plan of Meizhou cement industry (2009 Revised Edition) >, the Meizhou municipal Party committee, municipal government put forward to the tower as a leader, to Jiaoling as a base to build an annual output of 20 million tons of clinker cement production base in Guangdong development strategies and objectives. Meizhou city in the selection of sewage treatment plant sludge disposal process, can give full play to the advantages of the cement industry developed, CO disposal of sludge by cement kiln, to support the construction of the harmless sludge disposal facilities in Guangdong province. According to the strict control measures for the implementation of administrative licensing requirements for waste treatment, sludge disposal facilities operating units to apply for strict control of waste processing license, according to the law to engage in sludge disposal activities, promote the Meizhou city urban sewage treatment plant sludge disposal standard as soon as possible to prevent the two pollution, elimination of environmental safety Hidden danger.
C. Guarantee funds and uniform price
    The government should make corresponding concentrated sludge disposal price policy, to further improve the sewage treatment fee collection efforts and management level, the sludge disposal costs into the sewage treatment plant sewage treatment fee should include the cost of sludge treatment and disposal costs, the sewage treatment fee, financial subsidies and other ways to implement the sludge treatment and disposal costs, ensure that the sludge treatment and disposal facility operation. At the same time, governments at all levels should increase the construction of sludge treatment and disposal facilities for capital investment, for the inclusion of sludge treatment and disposal technology and equipment to encourage the development of countries to give financial and tax preferential provisions; to establish a diversified investment and operation mechanism, encourage through franchising and other means, to guide social capital to participate in the construction of sewage sludge operation and disposal facilities.
    Combined with real situation city and sludge disposal, learn From Meizhou city sludge treatment methods and problems, in accordance with the "sludge reduction, harmless, resource-based" processing principle to develop appropriate sludge treatment and disposal mode is problem each city and each province should pay more attention to.
