Sewage treatment plant operation and maintenance technical scheme

1.1 Trial operation management of sewage treatment plant

The trial operation of sewage treatment project is different from the trial operation of general building water supply and drainage project or municipal water supply and drainage project. The former includes the start and commissioning of complex biochemical reaction process, which is slow and time-consuming, and is strongly affected by environmental conditions and water quality and quantity, while the latter only needs the system water supply and the normal operation of equipment.

The trial operation of sewage treatment project is as important as the acceptance of the project. Through trial operation, the quality of civil engineering, equipment and installation engineering can be further tested, which is the basis for ensuring the normal operation process, and further achieving the environmental benefits, social benefits and economic benefits of sewage treatment projects.

Countless water treatment project trial run, not only to test the quality of the project, more importantly, to test whether the operation of the project can achieve the designed treatment effect. The content and requirements of the trial operation of countless water treatment projects are as follows.

(1) Test the quality of civil construction, equipment and installation works through trial operation, establish related equipment files and materials, and make suggestions on the design rationality and operation precautions of related machinery, equipment and instruments.

(2) Carry out load operation on certain general or special equipment and test its capacity. Such as the lifting flow and head of the pump, the air volume, pressure, temperature, noise and vibration of the blower, the oxygenation capacity or oxygen utilization rate of the aeration equipment, the operation stability of the mud scraping (drainage) machinery, the effect of the protection device, the mud scraping (drainage) effect, etc.

(3) The trial operation of a single treatment structure requires to achieve the designed treatment effect, especially the engineering using biological treatment method, to cultivate (domesticate) microbial sludge, and on the basis of achieving the treatment effect, to find the best operating process parameters.

(4) On the basis of the trial operation of a single facility, the joint operation and acceptance of the entire project shall be carried out. Ensure that the sewage treatment can meet the discharge standards.

1.2 Operation and management of sewage treatment plants

The operation and management of the urban sewage plant, like the operation and management of other industries, is a general term for the planning, organization, control and coordination of the activities of the medical plant, and is a part of the various management activities of the enterprise (such as: administrative management, technical management, equipment management, "three production" management), and is the most important part of the various business activities of the enterprise.

The operation and management of municipal sewage plant refers to the management of the whole process from the acceptance of raw sewage to the purification and discharge of "standard" sewage.

1.3 Basic requirements for sewage treatment operation and management

The basic requirements in the operation and management of urban sewage treatment plants are:

(1) On-demand production should first meet the basic requirements of the urban and water environment for the operation of the sewage plant, and ensure that the dry treatment capacity makes the treated sewage reach the standard.

(2) Economic production to treat sewage at the lowest cost, so that it is "up to standard".

(3) Civilized production requires operation and management personnel with new qualities to safely do a good job in production and operation with advanced technology and civilization.

1.4 Water Quality Management

The water quality management of sewage treatment plants (stations) is the core and purpose of each work, and is an important factor to ensure the "standard". The water quality management system should include: the responsibility system of water quality management agencies at all levels, the "three-level" (referring to environmental monitoring departments, head offices and sewage stations) inspection system, who knows discharge standards and water quality inspection system, water quality control and cleaner production system.

1.5 Responsibilities and management of operation personnel

The task of the operation and management personnel of the sewage treatment plant is to give full play to the advantages of various treatment methods, conduct scientific management according to the design requirements, make full use of the flexibility of various processes to make appropriate adjustments when the water quality conditions and environmental conditions change, find and solve abnormal problems in time, so that the treatment system can complete the purification treatment with high efficiency and low consumption. In order to achieve the ideal environmental benefits, economic benefits and social benefits.
