Description

Pretreatment Equipment for Sewage Water Quality Monitoring{A Pretreatment Equipment of Sludge or Sewage}

The present invention relates to a water quality monitoring device capable of monitoring the water quality of wastewater discharged from industries or livestock industries, and more specifically, a wastewater inlet path into which wastewater discharged from a number of factories is introduced is connected to a wastewater treatment facility, and wastewater In the water quality TMS (remote monitoring system), which measures and monitors the effluent water discharged through the effluent after treating the wastewater flowing through the inlet at the wastewater treatment facility, the quality of the water in the wastewater inlet passage where the wastewater flows into the wastewater treatment facility. TMS is connected and installed, and the quality of wastewater can be measured and monitored in real time before the wastewater flows into the wastewater treatment facility, so that when abnormal water quality is introduced, it is possible to respond in advance in the operation of the wastewater treatment process, thereby stabilizing the quality of discharged water. The present invention relates to a pretreatment device for wastewater for stable water quality monitoring of wastewater that significantly improves the water quality environment of effluent water by maintaining it within the standard.

Large-scale wastewater treatment facilities are used to collect and treat wastewater generated at industrial sites or agricultural and livestock sites. In the treatment of solids, organic matter, nitrogen and phosphorus contained in wastewater, physical, chemical and biological methods are used in parallel.

In recent years, domestic wastewater treatment facilities, including public sewage treatment facilities, measure and monitor the quality of discharged water through a water quality TMS (remote monitoring system).

This tele-metering system (TMS) remotely monitors the effluent that discharges the treated water treated through the wastewater treatment facility, measures the pollutants contained in the effluent, and regulates the discharge of wastewater through it. It is structured to be able to.

However, there is a limitation in that the conventional water quality TMS as described above is installed at the outlet (discharge path) side of a wastewater treatment facility and is monitored only by measuring the effluent finally treated through the wastewater treatment facility.

The discharge of malignant wastewater from the factory is often performed secretly at times when the monitoring of the supervisor is weak, and the abnormal water quality is not recognized in advance even when the inflow of such malignant wastewater, so it is treated at the point of discharge into the river through the wastewater treatment facility. Limitations arise in the following.

In other words, in the existing public sewage treatment facilities, water quality is monitored in the effluent TMS, so that the treated water quality is exposed to the standard value or higher, so that the water quality treatment process is reacted afterwards. It is impossible to cope with management.

This is pointed out as a limitation of wastewater treatment because most of the pollution of the discharged water finally treated through the wastewater treatment facility is more than the standard value, but it is mostly discharged to rivers, and there is no way out of coping with the treatment process afterwards.

Due to this necessity, there have been cases of temporarily installing and operating water quality TMS for process management at the inlet of wastewater treatment facilities, but due to the extreme water quality characteristics of factory wastewater, it is difficult to continuously monitor water quality due to contamination of the water quality TMS sensor. The situation is only monitoring the quality of the effluent water treated in the wastewater treatment facility.

This technology relates to a pre-treatment device so that the desired water quality measurement and monitoring can be performed stably at all times even in extreme water quality such as the junction of the wastewater pipe network or the inlet of a wastewater treatment plant.

In this case, the return pipe 122 is installed to be supplied with wastewater along the circumferential direction of the inner wall surface while communicating with the inclined portion of the first stage body portion 120a having a cone shape. Therefore, the wastewater flowing into the first stage body portion 120a through the return pipe 122 is strongly rotated (orbited) in the circumferential direction along the inner wall surface of the first stage body portion 120a to further enhance the purification ability. You can increase it.

Here, the flow of wastewater through the first stage discharge pipe 120b is achieved by the pumping force of the motor pump 141.

Therefore, the wastewater flowing into the interior of the second-stage body portion 130a through the first-stage discharge pipe 120b rotates rapidly along the circumferential direction of the inner wall surface portion of the second-stage body portion 130a to filter the solids contained therein. Therefore, the large specific gravity enters the wastewater inlet passage 101 through the two-stage outlet 130c together with the wastewater, and the solid matter with a small specific gravity is the motor pump 141 through the two-stage discharge pipe 130b together with the wastewater. ) Is supplied to the first purification cyclone 140.

In addition, since the first purification filter 142 must primarily filter wastewater, it is preferable to be configured with a coarse filter so as to increase its durability. Therefore, in the first purification filter 142, coarse solids are filtered and discarded, and fine solids pass through.

In addition, a first purification valve 143 for opening and closing wastewater is installed in the connection line of the first purification outlet 140c. As the valve is normally closed, the pressure loss of the pump can be minimized, and the wastewater discharged through the connection line of the first purification outlet 140c by opening the first purification valve 143 upon accumulation of solids is It is discharged to the wastewater inflow path 101 or other required places.

On the other hand, the second purification cyclone 150 is composed of a main cyclone (150a) and a subcyclone (150b) identical to the main cyclone (150a), one of the main cyclone (150a) and the subcyclone (150b) It is configured to be able to use selectively. That is, the subcyclone 150b is used when servicing the main cyclone 150a, and the main cyclone 150a is used when servicing the subcyclone 150b so that there is no gap due to maintenance time.

Since the second purification filter 154 must finally filter the wastewater, it is preferable to be composed of a fine filter so as to improve the filtering performance. Therefore, in the second purification filter 154, the purified wastewater is supplied to the wastewater storage tank 160 by completely filtering fine solids.

Here, the second main exit 153 is connected to the return pipe 122 provided in the first stage cyclone 120.

The first purification filter 142 provided in the first purification cyclone 140 of the present invention is provided as a more coarse filtration filter than the second purification filter 154 provided in the second purification cyclone 150 . Therefore, the first purification cyclone 140 filters large solids, and the second purification cyclone 150 filters fine solids, thereby dualizing the filtering function, thereby enhancing the durability of each purified cyclone.

When the second purification cyclone 150 configured as described above uses the main cyclone 150a, the main 1, 2, 3 valves M1, 2, 3 are opened and the sub 1, 2, 3 The valves (S1, 2, 3) are closed.

The contaminated water supplied to the second purification cyclone 150 is completely purified through cyclone filtration in the second main body part 151 and filtration through the second purification filter 154. Purified water, which is rotated while being returned to the return pipe 122 of the monocyclone 120 and has a small specific gravity, is supplied and stored in the pretreated water storage tank 160 for the water quality TMS 170.

In the present invention, the measurement of the water quality of wastewater flowing into the wastewater treatment facility does not accurately identify the legal water quality group, but confirms the sudden change in the continuously flowing wastewater, and confirms the inflow of malignant wastewater in real time. That is, the wastewater flowing into the wastewater inlet passage 101 is continuously purified by a plurality of cyclones and circulating reflux water to be introduced into the sensor to suppress corrosion of the sensor, but the degree of contamination of the purified water thus purified is determined by the wastewater inlet passage 101 Water quality items excluding SS can be measured from the pollution level of wastewater flowing into the tank. Through this, when the pollution level of the currently introduced wastewater changes abruptly, it is notified in real time to the wastewater treatment facility to accurately measure the state of the actually introduced wastewater, so that the malicious wastewater flowing into the wastewater treatment facility can be treated. At the same time, when the present invention is installed in a plurality of areas, there is an advantage of being able to check which factory the malicious wastewater is introduced.

In addition, the pretreatment device for monitoring the quality of wastewater according to the present invention can check the inflow of malignant wastewater by examining only simple items such as PH or T-P, rather than inspecting all water quality items, so it is possible to check water quality in real time while being simple.

In addition, the influent water of the first stage cyclone 120 slowly flows into the supply pipe 121 of the wastewater flowing through the wastewater inlet passage 101, and is discharged from the second purification cyclone 150 through the return pipe 122 at least three times. The purified contaminated water flows in at a high speed and provides a centrifugal force that generates a cyclone phenomenon inside. The water flowing into the supply pipe and the return pipe of the one-stage cyclone 120 is discharged to the upper portion of the water purified by the cyclone, and the contaminated water (or collateral) is discarded into the wastewater inlet passage 101, at this time, the return pipe 122 ), most of the purified water (contaminated water) rapidly introduced through the plurality of times passes out to the top and is moved to the two-stage cyclone 130 or the first purification cyclone 140. Therefore, most of the water transferred from the first-stage cyclone 120 to the second-stage cyclone 130 or the first purification cyclone 140 is contaminated water introduced through the return pipe 122, and pure water flowed through the supply pipe 121 The amount of wastewater becomes very small. Accordingly, the water moved to the wastewater storage tank 160 while passing through such a circulation structure a plurality of times is in a state of being purified to a fairly high level and does not have any adverse effect on the sensor measured by the water quality TMS 170.

As described above, the pretreatment device for monitoring the quality of wastewater according to the present invention connects the wastewater inlet passage through which the wastewater discharged from a number of factories is introduced with the wastewater treatment facility, and treats the wastewater flowing through the wastewater inlet in the wastewater treatment facility, and then discharge pipe In the water quality TMS (remote monitoring system) that measures and monitors the discharged water discharged through the wastewater treatment facility, the water quality TMS is connected and installed at the wastewater inlet before the wastewater is supplied to the wastewater treatment facility. Water quality can be measured and monitored, and when malignant wastewater is introduced, it is possible to track the inflow path of the bad wastewater, and at the same time, it is possible to dramatically improve the water quality environment of the effluent by providing information in advance to change and modify the wastewater treatment process.
