Description

  The present invention relates to a water and sewage system that links a water purification plant and a sewage treatment plant.

  Conventionally, the operation of water purification plants and sewage treatment plants has often been performed individually. However, the water distributed from the water purification plant is finally treated at the sewage treatment plant. In addition, the discharged water from the sewage treatment plant may affect the water quality in the vicinity of the intake of the water purification plant provided in the downstream of the river or in the water purification plant.

  Therefore, if information on operation is shared between water treatment plants and sewage treatment plants where service areas overlap or where water is taken and discharged from the same river, the water treatment plant and the sewage treatment plant can be operated efficiently. It is expected.

  As a method of sharing information related to driving, in addition to a method of mutually transmitting information of a monitoring control device installed in a machine via a communication line, JP 2003-67514 A and JP 2002-251505 A As is well known in the art, there is a system that distributes a result calculated by a WWW server to a Web terminal via a communication network such as the Internet.

  When the results obtained by sharing the operation information of the water treatment plant and the operation information of the sewage treatment plant are used as new information, the first advantage is that the inflow to the sewage treatment plant and the inflow water quality data are particularly It will be meaningful information.

  As a method for predicting or estimating the inflow amount of the sewage treatment plant from the distribution amount of the water purification plant, as known in Japanese Patent Application Laid-Open No. 2001-14034, the sewage inflow amount to the sewage treatment plant by a function of the first order lag and dead time. As is well known in Japanese Patent Application Laid-Open No. 2003-268811, the amount of water distribution is converted into the amount of sewage generated in each region, and the amount of inflow to the sewage treatment plant is calculated together with the amount of rain falling in each region. There are ways to do it.

In addition, when the result obtained by sharing the operation information of the water treatment plant and the operation information of the sewage treatment plant is used as new information, the second advantage is the water purification plant that the effluent quality of the sewage treatment plant affects. The water quality in the vicinity of the water intake and in the water treatment plant. Examples of water quality items that affect water purification treatment include COD, BOD, and other organic acids. As a method for predicting or estimating the influence, there is a water environment simulation method for a river water system known in Japanese Patent Laid-Open No. 11-184372, for example.
JP 2003-67514 A JP 2002-251505 A JP 2001-14034 A JP 2003-268811 A Japanese Patent Laid-Open No. 11-184372

  However, known techniques such as Japanese Patent Laid-Open No. 2003-67514 and Japanese Patent Laid-Open No. 2002-251505 provide driving support information based on individual information for each sewage treatment plant or water treatment plant. Coordination of the venue is not considered.

  In addition, a known technique such as Japanese Patent Application Laid-Open No. 2001-14034 predicts only the amount of generated sewage, and it is difficult to predict and estimate the amount of inflow during rainy weather.

  In addition, known techniques such as Japanese Patent Application Laid-Open No. 2003-268811 have to convert distribution amount data into sewage generation amount for each sewer subdivision area, taking into account geographical information, sewage pipe laying state, and water pipe laying state. Therefore, there is a problem that the amount of data to be handled becomes enormous and it takes a lot of work.

  In addition, known techniques such as Japanese Patent Application Laid-Open No. 11-184372 require a river basin geographical information, and therefore, there is a problem that it takes man-hours to handle a huge amount of data.

  In view of the above circumstances, in the present invention, in claim 1, information related to the operation of the water treatment plant and information related to the operation of the sewage treatment plant can be shared with each other, and the operation efficiency of each other can be dramatically improved. The purpose is to provide a water and sewage system that can take measures against accidents on the other side when a sudden accident occurs at either a water treatment plant or a sewage treatment plant, and prevent adverse effects due to the accident. It is said.

In order to achieve the above-described object, the present invention provides a water purification system in which one or both of a water purification plant and a sewage treatment plant, or the operation contents of both affect the other, through the communication line. Or, the data is taken from the sewage treatment plant and stored in a database, and in response to a request from the water treatment plant or the sewage treatment plant, the designated data is read from the database, and the request is made via the communication line. A data center that delivers to the water treatment plant that has been put out or the sewage treatment plant, and the water purification plant collects data designated in advance and transmits the data to a designated transmission destination via a communication line, and communication performs a process to capture the data of the sewage treatment plant side from the data center via a line, the sewage treatment plant, said pre-specified data Detase Collected from data database, it executes the process of capturing data of the water treatment plant side process of transmitting to the designated transmission destination via a communication line, and via the communication line from the data center, the data center, Furthermore, inflow of the sewage treatment plant using at least one of data transmitted from the water purification plant, past data stored in the database, and meteorological information supplied via the communication line. Inflow amount prediction value calculation / distribution means for calculating a volume prediction value and distributing it to the sewage treatment plant via the communication line, data transmitted from the sewage treatment plant, and past data stored in the database Or the water quality prediction value of the water treatment plant using at least one of the meteorological information supplied via the communication line, and the communication line And a water quality prediction value calculation / distributing means for distributing the water treatment plant via, is characterized in that is operated in cooperation with said sewage treatment plant and the water treatment plant.

  According to the present invention, the information regarding the operation of the water treatment plant and the information regarding the operation of the sewage treatment plant can be shared with each other, and the operation efficiency of each other can be dramatically improved. On the other hand, even if a sudden accident occurs, it is possible to take countermeasures against the accident on the other side and prevent adverse effects due to the accident.
