Face problems

China's sewage treatment is faced with serious water pollution, late start of sewage treatment, poor foundation and high requirements. In recent years, the construction of urban sewage treatment has made great progress. By the end of June 2005, 661 cities had built 708 sewage treatment plants, with a treatment capacity of 49.12 million cubic meters per day, more than twice that of 2000. Last year, 16.28 billion cubic meters of urban sewage was treated, an increase of 43 percent over 2000, and the urban sewage treatment rate reached 45.7 percent. However, the sewage treatment capacity of the vast majority of cities cannot meet the actual needs. There are still 297 cities in China that have not built sewage treatment plants, of which 63 are cities at the prefecture level or above, including eight big cities with a population of more than 500,000. 54 cities are located in key river basins and within the scope of the regional "Tenth Five-Year Plan". There are no sewage treatment facilities in more than 50,000 cities and towns, 3.7 million villages and 900 million people.

Compared with the international, China's urban sewage treatment rate is low, the main reason is that China's urban sewage treatment plant construction lag. According to the information, the United States has an average of one sewage treatment plant per 10,000 people, and the United Kingdom and Germany have one sewage treatment plant per 7,000 people. One sewage treatment plant for 8,000 people. In China's urban population, there is only one sewage treatment plant for every 1.5 million people. According to the national sewage treatment situation reported by the Ministry of Construction, the completed sewage treatment plant, in addition to the commissioning operation, there are not normal operation, the main reasons are: first, the poor management of sewage treatment organization, resulting in some sewage treatment plants have been built for half a year or even nearly a year is still not running. Second, some cities that have built sewage treatment plants have not yet levied sewage treatment fees, or the charging standard and collection rate are low, and the operating funds of sewage treatment facilities are difficult to guarantee. Third, the construction of sewage collection pipe network lags behind, and the operation load rate of sewage treatment plants is low, and even difficult to operate. Fourth, the local supporting funds are not implemented, affecting the commissioning and operation of sewage treatment plants. In addition, there are some urban sewage treatment plant design scale is too large, too advanced, resulting in partial idle facility capacity can not give full play to the benefits.

Current situation

Shortage of funds for the construction of sewage treatment plants; Maintenance of imported equipment and development of spare parts; There is a gust of wind in the selection of sewage treatment process, and the popular process is not selected according to the actual situation of the region. [1]

1. Operational services and efficient supervision have become prominent issues. Operation management is becoming more and more important and prominent. Due to the large number and wide distribution of subordinate enterprises, higher requirements are also put forward for supervision.

2, sewage treatment enterprises in the operation stage, the requirements for management level, cost control requirements are constantly improving.

3, sewage treatment enterprises how to promote the management experience of excellent sewage treatment plants in the industry to all plants and stations to improve the overall management level of the company.

Management method:

Remote monitoring

Through the collection, transmission, storage of the operation data of each sewage treatment plant and pumping station, and preliminary processing, personnel at all levels of the enterprise can grasp the production and operation situation at any time. It is more suitable for the remote supervision of group enterprises on subordinate project companies.

Automatic collection and real-time storage of online instruments and equipment operating data in the enterprise automatic control system;

The production operation of the enterprise is displayed graphically in real time and can be viewed remotely through the network;

Historical production operation data can be quickly found and viewed at any time;

The production and operation data can be visually compared by bar chart, pie chart and curve chart.

Automatically monitor all kinds of production operation data, find abnormal real-time alarm;

The alarm processing process and processing results can be tracked and recorded;

Historical alarm information can be queried, summarized and statistically analyzed;

The alarm processing plan can be prepared to provide reference for alarm processing and improve processing efficiency;

Production run

All kinds of information that need to be recorded in the production and operation process of water enterprises are digitized, and operations such as classification, summary, calculation and export of these data are implemented to reduce data duplication, improve data sharing, greatly reduce the workload of personnel at all levels and improve work efficiency; Combined with years of report management experience of sewage treatment experts, a set of statistical analysis and reports that fully meet the management of water enterprises has been developed and formed, so that the data statistical analysis and report generation of enterprises are more standardized and efficient. All kinds of record data can be automatically generated and exported to excel, and managers at all levels can view it at any time according to their rights, providing basic data support for guiding production process management.
