First, as shown in FIG. 1, the sewage overflow water disinfection system equipped with an automatic water quality measurement device is particularly suitable for treating a combined sewage overflow overflow (CSO: Combined Sewerage Overflow), which basically measures the water quality of the sewage overflow water. The measuring apparatus S and the disinfection apparatus A which disinfects sewage overflow water are provided.

Water pollutants generated in urban areas can be classified into point sources and nonpoint sources by source. Since nonpoint source sources are generally associated with surface runoff due to rainfall, changes in daily and seasonal emissions are large and difficult to predict and quantify.

In particular, rainfall runoff from urban areas is mainly discharged to sewer systems near the city through sewage pipes, which are combined with the combined sewer overflow ('CSO' or less) when the combined sewer pipe exceeds the capacity of sewage pipes. And separated sewer overflows (combined below 'SSO'). CSOs and SSOs account for the largest share of nonpoint pollution loads in urban areas and, as indicated by foreign studies that have been found to significantly deteriorate urban stream ecosystems, as well as improving water quality in urban rivers, unless there are measures to deal with CSOs and SSOs. It was difficult to expect.

Rainfall runoff is most affected by watershed characteristics and rainfall events. Since rainfall runoff is collected and transported through a combined sewer system along the surface, it is combined with sewage and finally overflowed from the outlet, thus affecting the water quality characteristics of the CSO. The arguments are compounded.

Combined sewage pipe overflow overflows contain various pollutants such as suspended solids and organics, and are known to cause pollution of rivers. In general, urban runoff during rainfall is known to contain a large amount of harmful substances such as oils, heavy metals, aromatic hydrocarbon compounds, as well as pollutants contained in sewage itself. These pollutants increase the discharge pollutant because a large amount of the pollutant is discharged to the discharge vessel through the overland port in a short time. In urban areas, due to the continuous development of the impermeable layer, the rainfall delivery time is shortened and the runoff rate is increased.

The characteristics of combined sewer drainage and sewage can be categorized into four types according to rainfall duration, and the pollution characteristics of runoff from each section are also different. Representatively, a graph of BOD concentration change during rainfall is attached to FIG. 2.

   end. First-Flush

Combined Sewer systems contain relatively high concentrations of pollutants due to pre-drying days, rainfall intensity, land use type and impervious pavement and surface sediment wash, and rainfall characteristics and land use status of the survey area. There are various characteristics of the pollution load caused by the light.

   I. Extended Duration Flow

Rainwater and living sewage are mixed in the outflow flow due to the continuous rainfall after the initial rainfall, and have a lower pollution load than the initial rainfall.

   All. Post Rainfall Runoff

Effluent discharged after rainfall, water quality is similar to extended duration flow and consists mostly of domestic sewage and infiltrated ground water.

   la. Dry Weather Condition Flow

Living sewage without rainfall impacts.

As described above, sewage overflow treatment during rainfall is preferably focused on initial rainfall. Although it is difficult to clearly define the limits of the initial rainfall runoff, commonly referred to as First Flush, the impact on the water quality characteristics through the generation of the runoff during the early rainfall periods is that It absorbs fine dust and flows along the surface to dissolve and contain dissolved and suspended contaminants. In addition, as the inflow flow increases, sediments in the conduit are disturbed and suspended, so that the load of the overflowed water generated at the end of the rainy season in the early stage of rainfall shows a significantly higher pollution concentration than the dry-water sewage.

In the US, the EPA defines rainfall from the beginning of the rainfall to about 30 minutes as initial rainfall, but it is difficult to interpret in terms of time without considering the effects of rainfall characteristics, regional characteristics, and overflow control facilities.

Another theory that defines initial rainfall is to interpret the increase in the concentration of contaminants (particularly TSS) and then the time to recover to the concentration of dry sewage (Thomas and Saui, 1986). This theory is more reasonable than the early rainfall of other temporal concepts.

Rainfall generation characteristics in Korea are generally long in the preceding dry days, and especially in winter, the rainfall frequency and rainfall intensity are small, resulting in higher concentrations of spring overflows compared to other seasons. As a result, solid sediment deposition in sewage pipes is reported as 5-30% of the daily sewage load in the United States and 20% in Korea.

Even in small rainfall intensity, overflowing water occurs in domestic stormwater, and there are many places where overflow occurs from the beginning of rainfall when the water usage time overlaps with the period of rainfall.

The water quality characteristics of monthly streams according to the rainfall duration by pollutant compared to Cheongcheon were significantly higher than that of Cheongcheon at the beginning of rainfall, but lower than Cheongcheon at longer rainfall durations. SS is higher than Cheongcheon regardless of rainfall duration.

For the amount of solids deposited in sewage pipes, EPA reports that approximately 5-30% of the daily sediment load flowing into sewage pipes is deposited in the conduit (Sewer and Tank Sediment Flushing: Case Studies, EPA, 1998).

In Korea, sedimentary deposits are estimated to be about 20% of daily pollution load (Sewage Maintenance Basic Plan, Seoul, 1998). Given that, the situation is likely to be more severe. According to the report on the best management technology of water supply and sewer pipe network (Korea Institute of Construction Technology, 2002), it is assumed that 25% of the daily urban pollution load is deposited in sewage pipes and that rainfall occurs with 4 days prior to the dry season and 2 hours of rainfall duration. It can be said that the influx of daily pollution load is overflowed into the stream within 2 hours of the start of rainfall. In particular, considering that the rainfall characteristics in Korea rarely fall in winter, the effect of monthly water discharged to spring streams on river water pollution is enormous.

 Regarding the overflow characteristics of storm sediments in Korea, the difference between the time of overflow and the duration of overflow in storm sediments occurs depending on rainfall characteristics such as rainfall intensity, rainfall duration, runoff coefficient, etc. Is usually only a few millimeters. In particular, when the evening time when the water usage of local residents increases and the rainfall occurrence time coincide, the overflow phenomenon occurs from the beginning of the rain, which causes high concentration of sewage into the river.

Thus, it is a departure from the conventional method of combined sewage overflow (CSO)

If only a certain capacity is processed and the flow rate is exceeded,

There is an urgent need to present measures to discharge only when the water quality measurement criteria are met and when the water quality is not met.

In addition, it is desirable to implement a treatment system using a pressurized flotation method, which has a superior treatment efficiency with respect to particulate and dissolved treatment materials compared to a facility employing a general vortex method.

Meanwhile, as of the end of 2004, the distribution rate of sewage pipes installed in Korea was 68.1%, of which 58% were confluent and 42% were categorized. In this specification, although the description focuses on the treatment for the combined sewage overflow water, the concept of the present invention can also be applied to the storm sewage overflow water in the sewage sewage treatment area, the present invention should not be construed as a limitation.

As shown in Figure 1, the sewage overflow water disinfection system according to the present invention comprises a water quality automatic measuring device (S) for measuring the water quality of the sewage overflow water, and a disinfection device (A) for disinfecting the sewage overflow water.

In addition, the present invention discharges the overflow water when the measured value of the automatic water quality measuring device (S) meets the reference value, and the controller (C) for transferring the overflow water to the disinfection device (A) when the reference value is not satisfied. It is made to include. The controller is configured through a programmable logic controller (PLC), a microcomputer, or the like, and receives and reads the measured values of various water quality automatic measuring devices (S), stores data, and determines whether or not the overflowed water is discharged. As shown in FIG. 1, the valve V (or gate) is displaced to determine the direction of overflow of the overflowed water.

Before draining sewage overflows (CSOs) into streams such as rivers, it is necessary to kill or deactivate pathogens that are harmful to humans, especially chlorine disinfectants. Most National Pollutant Emissions Reduction (NPDES) permits require the minimum contact time required at peak flow rates to ensure that disinfectants are in sufficient contact with the effluent to sufficiently disinfect pathogens in the effluent with potentially poor water quality.

High-intensity mixing of chlorine disinfectants in effluents can be achieved in chlorine contact baths, ie disinfection baths, which have a shorter residence time than most required by regulatory standards. Therefore, additional treatment with chlorine prior to the equalization of the flow rate or the gravity settling stage may be considered to give additional contact time to ensure complete treatment.

Determination of rainwater inflow of toxic substances such as chlorine using the automatic water quality measurement equipment located in the front of the sedimentation basin is due to the high odor and pollution load in the sewage pipe overflow waters. It was bad and found to be efficient through several routes that it was necessary to achieve chlorine injection by automatically measuring water at this time.

The automatic water quality measuring device may be configured as a device for measuring some or all of the COD, BOD, TOC, T-N, T-P, DO and pH.

The measurement items and measuring method of water quality automatic measuring equipment are summarized as follows.

A controller (C) configured through a programmable logic controller (PLC) or a microcomputer, etc. determines the flow direction (discharge or disinfection treatment) of the overflow water according to the measured values of various automatic water quality measuring devices (S) and stores the water quality data. According to the degree of pollution, the operating power (air supply increase / decrease) of the stirrer St (or air supply means such as an acid pipe) is appropriately changed in the disinfection apparatus A. The system can be configured to transmit operational status, etc., to the central control room, contributing to the overall overall management of the jurisdiction.

Automatic sewage sewerage (S) for combined sewage sewers, particularly sedimentation basins (T10) (representing the sedimentation basin among the various sewage sewer systems, which may be a component of various other sewer or sewer sewers) And when the overflow water does not satisfy the discharge D1 water quality according to the determination of the controller C, the overflow water is transferred to the disinfection device A through the valve C.

In Figure 1, the overflow water disinfection device (A) comprises a chemical supply means (D), the chemical supply means (D) is a chemical tank (liquid or powder), chemical transport means (pump, etc.), mixer (powder and water) It is used when mixing the solution, such as, or used when the two or more chemical mixtures input (eg line mixer), flow meter and the like, and also controlled by the controller (C). In addition, the tank-type disinfection tank to ensure the mixing and retention treatment of the monthly water and chemicals, it is preferable that a stirrer (St) is provided in the disinfection tank for a smooth mixing reaction.

In FIG. 1, the disinfected overflowed water is discharged into the stream (D2), and the unflowed sewage, rainwater, and sewage are treated by various known treatment methods, for example, to precipitate and remove solid particles as shown. After the primary sedimentation battery (T20), aeration tank (T30) for advanced water treatment, and various subsequent treatment units (P40) such as secondary sedimentation battery (T40) to finally settle the foreign matter is treated, and finally discharged (D3).

In chemical disinfection, especially chlorine disinfection, the amount of chlorine injected must be changed depending on the characteristics of the overflow water. If ammonia is present in the overflow water, chlorine reacts preferentially over other compounds to produce chloramine. There may also be low concentrations of chlorine consuming compounds in the overflow water, the amount of which varies fluidly. Therefore, it is necessary to determine the amount of chlorine-consuming compounds present in the sewage and to inject more chlorine to limit the activity of microorganisms. At this time, if the amount of chlorine is injected into the sewage much more than the amount of the chlorine consumption compound, not only waste of chlorine but also increase the amount of SO2, etc. required for desalination, economically lost. At this time, if the amount of SO ₂ required for desalination is not properly determined, it may cause the inflow of chlorine. On the other hand, if the amount is injected too small than the chlorine demand of the sewage, there is a problem that can not kill all the microorganisms present in the sewage can lead to the influx of pathogenic microorganisms.

The chlorine disinfection process currently being carried out in sewage treatment plants determines the amount of chlorine to be injected by running a titration test in a batch reactor and monitoring the breakthrough point. The amount of SO ₂ or Na ₂ SO ₃ added for desalting is also determined by this. However, this method does not respond to dynamic changes in the influent, since a single measurement determines the required amount of chlorine and desalting agents for the water being treated for one or more hours. In addition, since many of the sewage treatment plants in Korea do not have reactors of a size sufficient to give sufficient chlorine contact time, sterilization should be completed in a short time (about 15-30 minutes). To ensure robust sterilization in such a short time, more hypochlorous acid (HOCl) is required, which is much more potent than the monochloramine (NH ₂ Cl) before the breakthrough. For this reason, sewage treatment plants are usually injecting excessive amounts of chlorine and desalting agents to achieve stable disinfection targets.

The chlorine injection method used in the chlorine disinfection process can be largely divided into two methods, an automatic total residual chlorine measuring method and an ORP method. At present, the total amount of residual chlorine automatic measuring device developed at home and abroad measures the amount of chlorine remaining in the water, and cannot distinguish between hypochlorous acid and monochloramine. For this reason, they are often used with monochloramine automated analyzers. These chlorine injectors are expensive and require frequent calibration and maintenance. For this reason, it is not widely used in sewage treatment plants.

The inventor of the present invention discloses a technique related to chlorine disinfection and desalination made through Patent No. 10-0724707 (Registration Date May 28, 2007) [Method and Control Device for Chlorine / Dechlorinate Injection Determination and Control Device and Sewage Purification System Using the Same].
