Description

{Water Pollution Measuring Devices}

The present invention relates to a water pollution degree measuring apparatus, and more particularly, to a water pollution degree measuring apparatus capable of easily measuring a water pollution degree of sewage passing through a manhole.

Generally, a sewer pipe refers to a conduit that collects sewage discharged from various sewers and sends it down to the sewage treatment plant. These sewer pipes are arranged in the shape of a twig (male) since they are installed along the natural flow of the sewage due to the gradient of the treatment area.

The sewage pipe is buried underground, and it is difficult to confirm the condition of the pipe or the quality of the sewage after the installation is completed.

It also takes a lot of time and effort to measure the water quality of sewage pipes. The sewage treatment plant is installed at the downstream of the sewage pipe and treats pollutants contained in sewage water by physical, chemical and biological methods and discharges it to natural water system.

The treatment efficiency of the sewage treatment plant is influenced by the pollution degree and the flow rate of the inflow sewage flowing into the sewage treatment plant. Especially, when the microorganism is treated, not only the sewage pollution degree is too high but also the sewage pollution degree is too low, . Therefore, it is preferable that the water quality and the flow rate of the inflow sewage introduced into the sewage treatment plant are maintained as uniform as possible.

However, the sewage or sewage discharged through the sewage pipe fluctuates with the elapse of time, and even if the sewage pipe is installed, if there is a fault in the sewage pipe, the sewage, groundwater or stormwater flows from the outside, .

A typical phenomenon caused by the failure of the sewer pipe is infiltration and infiltration (infiltration).

The infiltration water means that the groundwater and stormwater penetrate into the pipeline through the disturbance such as breakage of the sewer pipe, poor connection of the pipe joint and poor connection of the connection pipe. Influent water means that sewer failure of a manhole, a rain gutter, a roof trough, and a basin drainage pipe are connected by a conduit system and the stormwater is introduced into the pipe.

Such infiltration water and inflow water increase the flow rate in the sewage pipe, thereby deteriorating the water-feeding ability and lowering the sewage concentration in the sewage treatment plant, thereby lowering the treatment efficiency of the sewage treatment device.

On the contrary, when the groundwater level is lower than the sewerage line, the leakage water leaks from the poor part of the pipeline, which causes the groundwater to be polluted, and the sewage water flow rate to the sewage treatment plant is reduced to reduce the sewage treatment efficiency.

In this way, the inflow of infiltration water and inflow water due to the failure of the sewage pipe is closely related to the water quality and flow rate of the sewage, and is also closely related to the treatment efficiency of the sewage treatment plant.

For example, when wastewater containing high concentrations of pollutants such as livestock wastewater or factory wastewater flows into the sewage pipe, the pollutant concentration of the sewage rapidly increases, and when the groundwater or the rainwater is introduced, the pollutant concentration of the sewage rapidly decreases.

Therefore, a means for measuring the quality of sewage water flowing into the sewage treatment plant is required in real time by measuring the quality of the sewage water in the sewage pipe.

For example, Patent Document 1 below discloses a sewage treatment plant control method and system using chlorine ion concentration in a sewer pipe, and a chlorine ion meter for this system.

The chlorine ion meter according to the following Patent Document 1 is installed in a sewerage treatment area having a predetermined area including at least one sewage treatment plant and is installed on a sewer pipe in a plurality of monitoring areas divided in consideration of the morphological characteristics of the sewer pipe and the land use characteristics A plurality of chlorine ion meters for measuring chlorine ion concentration in the sewage and transmitting the measured chlorine ion concentration data to a remote site through wired / wireless communication means; A flow meter installed at the downstream of the sewer pipe in each monitoring area to measure the flow rate of the sewage and transmit the measured flow rate data to a remote site through wired / wireless communication means; The chlorine ion concentration data received from the chlorine ion meter is connected to the plurality of chlorine ion meters and the flow meter through wired / wireless communication means. The chlorine ion concentration data is compared with the comparative chloride ion concentration stored in the database The flow rate data received from the flow meter is stored, and the flow rate variation is compared with the comparison flow rate stored in the database. The flow rate of the flow-in water flowing into the sewage treatment plant A main server for evaluating the quality of water and the flow rate of the water; A sewage treatment plant management server connected to the main server through wired / wireless communication means and controlling the operation of the sewage treatment device according to the quality and flow rate of the inflow sewage transferred from the main server.

The following Patent Document 2 discloses an " observer upper protector ".

In the observer's upper protection device according to the following Patent Document 2, an observer excavated in order to measure the water quality or the water level of the ground water through the sensor installed therein is formed into a hollow structure and extended to the observer, Formed tube; A cover for closing the upper part of the observer by closing the upper end of the extension pipe, the cover having a size covering the flange and rotatably installed on the extension pipe through the hinge means; And a sheath member installed on the lid and installed in the extension pipe, the lid emerging when the extension pipe is opened, and the installation of the sensor and the lifting work of the sensor are facilitated by walking the electric wire of the sensor.

Korean Patent Registration No. 10-0744630 (registered on July 25, 2007) Korean Patent Registration No. 10-0765968 (registered on October 4, 2007)

However, according to the prior art observer's upper protection device, it is convenient to raise and lower the sensor by the pulley member installed in the extension pipe, but it can not protect against the breakage or shock of the sensor when the sensor is moved up and down. The contamination state can not be measured in real time, and the sensor can not be stably installed.

The apparatus for measuring the water pollution degree according to the embodiment of the present invention measures the water quality by the sensor assembly 50 installed inside the pipe 30 in order to measure the quality of the water discharged through the sewage pipe 20.

That is, the sensor assembly 50 installed inside the pipe 30 measures the water pollution degree introduced through the perforation hole 31 by the sensor 62. This water pollution degree is measured by a pH sensor measuring the acidity of the water and a conductivity sensor (CI) measuring the chloride ion of the water.

The pH sensor measures the acidity or the degree of alkalinity of the water, and the conductivity (CI) sensor measures the ionic material (Mg, Ca, etc.) contained in the rain.

The sensor 62 sends the measured signal to the measuring instrument, and the measuring instrument analyzes the signal transmitted from the sensor 62 to detect the water contamination degree.

As described above, the sensor 62 for measuring the water quality of the water is used for a long period of time, so that foreign matter or the like sticks to the sensor 62, and the manager or the like exchanges or maintains the sensor 62.

In order to replace or maintain the sensor 62, the manager or the like opens the cover 41 by holding the handle 42. Since the cover 41 is rotatably installed around a hinge (not shown), the cover 41 is opened around the hinge.

The manager or the like pulls up the chain 51 provided on the cover 41 in a state in which the cover 41 is opened. As the chain 51 is pulled up, the sensor assembly 50 ascends along the pipe 30.

The manager or the like separates the second body 56 from the first body 53 in order to carry out maintenance work such as replacement or cleaning of the sensor 62.

The second body 56 is separated from the sensor holder 58 in a state where the locking lever 57 of the second body 56 is released. When the second main body 56 is thus separated, the manager or the like cleans the sensor 62. When the second body 56 is detached, the sensor 62 may be replaced as needed.

On the other hand, the manager or the like can selectively install any one of the two sensors 62 in measuring the contamination of the water quality. That is, the sensor assembly 50 may be provided with only one of a pH sensor and a conductivity (CI) sensor. In order to measure the pH of the water, a pH sensor is installed. When the conductivity of the water is to be measured, a conductivity sensor is installed.

In addition, it is needless to say that the sensor 62 may be provided with other sensors depending on the pollutants to measure the contamination of the water quality.

When the replacement or maintenance of the sensor 62 is completed, the second main body 56 is engaged with the fixing groove 55 of the first main body 53 and the locking lever of the second main body 56 57 are hooked on the hook 54 of the first main body 53 and locked.

When the assembly of the sensor assembly 50 is completed, the manager or the like descends the sensor assembly 50 into the pipe 30. This lowering sensor assembly 50 does not impact the sensor 62 since the support 60 first contacts the bottom surface of the manhole 10.

The sensor assembly 50 is stably installed on the bottom surface of the manhole 10 by the support 60 and the second body 56.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.
