Safeguards for sewage treatment

Crack the difficulties of sludge disposal and achieve harmless promotion of resources

1. Construction tasks. Sludge disposal facilities should be included in local sewage treatment facilities construction regulations

Row. The existing sludge disposal capacity can not meet the needs of cities and counties, to speed up to make up

Gap, town and county sludge disposal should be considered as a whole. Eastern region city, east and west

Large and medium-sized cities in the Ministry and cities with conditions in other areas will speed up the reduction of sludge filling

Buried scale, and actively promote the utilization of sludge resources. During the "14th Five-Year Plan" period, new sludge (including

Water rate of 80% wet sludge) harmless disposal facility scale is not less than 20,000 tons/day.

2. Technical requirements.

Harmless disposal of sludge. New sewage treatment plants must have clear sludge sites

Set the path. Encourage the use of thermal hydrolysis, anaerobic digestion, aerobic fermentation, drying and other methods

Carry out harmless treatment. Encourage the use of sludge and kitchen, kitchen waste jointly treatment facilities

To improve the comprehensive disposal level of urban organic waste. Develop a collaborative sludge disposal system

When constructing, the operation and process of existing local sludge disposal facilities should be fully considered

Use case.

Sanitary landfill disposal of sludge. Limit the sludge that has not been dehydrated to meet the standards

Landfill landfill. If collaborative disposal is adopted, sanitary landfill can be used as collaborative disposal

Emergency measures in case of facility failure or maintenance.

About sludge resource utilization. In the realization of sludge stabilization, harmless disposal premise

Next, steadily promote the utilization of resources. After the harmless treatment of sludge meets the relevant standards, it can

It is used for land improvement, afforestation of wasteland, nursery care, landscaping and agricultural utilization. drum

Encourage the recovery and utilization of sludge energy resources, and promote the use of large and medium-sized cities with scarce land resources

"Biomass utilization + incineration", "drying + land use" and other models. Promote the incineration of sludge ash

Utilization of slag building materials.

Fourth, strengthen operation and maintenance

1. Improve assessment and incentive mechanisms

The objective tasks of centralized collection of municipal domestic sewage and utilization of recycled water are included in the local phase

Close planning, implementation of the main body of responsibility, strengthen supervision and assessment. Build to reduce performance by pollutants

In the oriented assessment system, when the government and the enterprise sign the project agreement, the sewage should be treated

The core indexes are the concentration of pollutants, the reduction amount of pollutants and the harmless disposal rate of sludge

The standard is included in the scope of assessment, and the linkage assessment of project construction and operation effect is carried out. Put into operation

As an important indicator, strength and level are included in the selection criteria of project construction and operation enterprises.

(2) Promoting professional operation and maintenance

The urban people's government shall be the master of the management and maintenance of urban drainage and sewage treatment facilities

To promote the confirmation and transfer of ownership of non-owner municipal management sections or facilities. Establish locally based,

A stable professional team of personnel, the establishment of a normal construction management mechanism, in strict accordance with the phase

Implement operation and maintenance of standard quota. Promote and implement the integration of water supply and drainage, "factory - network - river.

"(Lake)" integrated professional operation and maintenance to ensure the systemization of sewage collection and treatment facilities

And integrity. Encourage residential communities to entrust the maintenance of internal pipe networks to municipal drainage networks

The operation and maintenance unit shall implement and establish a cost guarantee mechanism shared by the government and residents. strengthen

Personnel training, improve the level of professional skills, to ensure the safe and stable operation of facilities. Extension area

Construction and operation of projects with different profit levels in the domain. Central enterprises are encouraged to fulfill social obligations

Responsibility, give play to the advantages of professional large-scale construction and operation.

3. Promoting the development of information systems

With local people's governments as the main body of implementation, urban sewage treatment facilities shall be established according to law

Management information system and regular update, or rely on the existing platform to improve the relevant functions, to achieve city

Town sewage facilities information, ledger management. Promote drainage households, trunk branch pipe networks, pumps
