Description

Smart wastewater reusing system using rainwater and graywater}

The present invention relates to a smart water treatment technology using rainwater and graywater, more specifically, by selectively using the mixing of rainwater (rainwater) collected on the roof and roof of the building while omitting the active sludge process or Alternatively, after measuring the concentration of at least one wastewater selected from the wastewater used for washing, showering, washing, and cleaning, the sewage treatment circulated water from the sewage treatment may be cleaned, toilet water, landscape water, It is not only used for various and useful purposes such as sprinkling water, agricultural and industrial water, cooling water, and river maintenance water, but also a lot of savings in terms of water consumption, production cost, etc. Smart water treatment system using stormwater and storm water to improve It is about.

In general, systems for treating raw water such as surface water, surface water, sewage, brine, seawater, etc. are designed to have multiple stages of filtration, including successive treatment steps of flocculation, sedimentation and sedimentation. One of the raw water treatment methods is activated sludge treatment. It is based on the Activated Sludge Process (ASP), which is filtered to remove sludge content and suspended solids, solids and pretreatment of raw water.

At this time, an aeration unit or aeration tank is provided for injecting air into the tank to supply air to the treated raw water, and the raw water treated to supply air is supplied to a settling tank for further separation and sludge removal, and then further filtration and sterilization. The effluent is generated through the steps.

However, such an activated sludge treatment (ASP) system requires a long time, requires a large site, and generates a large amount of sludge.

On the other hand, raw water treatment systems other than the activated sludge treatment system include the use of membrane bioreactors (MBRs), which include the initial stages of suspended solids removal and pretreatment, and The step of providing the aeration tank is similar to the above activated sludge treatment system, but the MBR treatment is replaced by the precipitation tank and further filtration or sterilization treatment.

To this end, the MBR treatment employs a special membrane used to treat raw water with 5-12,000 mg / L of total suspended solids (TSS), and the MBR treatment uses ultrafiltration (UF). Ultra-filtration membranes and microfiltration membranes are used, and the pore sizes of the membranes range from 0.003 mm to 0.01 μm.

The MBR treatment usually immerses the membrane in a Bio Reactor, and the immersed shape depends on the bubble aeration device for the formation of the mixture and for limiting membrane fouling, the aeration being determined by the suspended solids. Persisting, cleaning the surface of the membrane, and also supplying oxygen to the microorganisms to induce more efficient degradation and cell synthesis.

On the other hand, apart from the systems for treating raw water such as surface water, surface water, sewage, brine, seawater, etc., rainwater is collected and treated to be used for living water, landscaping water, and industrial water. There are facilities for use, and these excellent use facilities began to expand and expand in earnest since 2000, and a number of installations were made in 2008. In order of ㎥, sports facilities 5,427㎥, school facilities 4,632㎥ and public buildings 3,013㎥, total storage capacity is 54,044㎥, which utilizes 652 thousand tons annually.

Further, the sewage use circulating water treated by the sewage treatment system may be used for cleaning water, toilet water, landscaping water, sprinkling water, agriculture, and the like, as disclosed in Korean Patent Publication No. 10-2009-0127270 (published Dec. 10, 2009). It can be used for various and useful purposes such as industrial water, cooling water, and river maintenance water, and it can not only bring a lot of savings in terms of cost savings such as reducing water consumption and reducing production costs, but also significantly improving the water circulation system. In addition, the water treatment system includes both water supply and drainage facilities and utilization facilities. Therefore, the mandatory water supply system includes accommodations, baths, and other facilities with a building area of more than 60,000 m ² , and other facilities such as large stores, logistics facilities, and transportation facilities. , Business facilities, correctional facilities, broadcasting stations and telegraph stations.

Here, the total water capacity of the water treatment system is 2,048 thousand ㎥ / day, and the individual facilities of other facilities such as large stores, transportation, business, correction, broadcasting stations, and telegraph telephone stations are small, while the number of locations is large, accounting for 63% of the total capacity. It occupies 1,283 thousand ㎥ / day, which is the largest, followed by plant facilities of 515 thousand ㎥ / day (25%), non-mandatory facilities of 228 thousand ㎥ / day (11%), accommodation and bathing facilities 222,000 ㎥ / day (1.1 %) The installation is running.

However, the use of sewage materials through the conventional heavy water treatment process is not only the utilization of the washing water and the river maintenance water in the sewage treatment plant, but the active expansion is not made, the biggest reason is the economic reason.

In other words, the existing water supply facilities are not only economical but also economical due to high site and maintenance costs due to the biological processes required in the sedimentation basin, filter paper, and disinfection facilities. The different systems add to the confusion of process selection, and it is difficult to secure water quality standards according to the use, and most facilities are not actually used and are left unattended.

Accordingly, the present invention is to improve the conventional problems as described above, selectively using the mixing of rainwater collected on the building roof and roof while omitting the active sludge process, as well as washing, washing, washing and cleaning By monitoring and controlling the inlet part of the Sewage Treatment System to measure the concentration of at least one Graywater selected from the effluents used in the waste water, etc., the circulating water used in the sewage treatment can be used for cleaning, toilet water, It can be used for various and useful purposes such as landscaping water, sprinkling water, agricultural and industrial water, cooling water, and river maintenance water, and it can expect a lot of savings in terms of cost such as water consumption reduction and production cost.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a configuration diagram of a smart water treatment system using rainwater and mixed wastewater in an embodiment of the present invention, Figure 2 is a structural diagram of the rainwater drainage in an embodiment of the present invention, Figure 3 is an embodiment of the present invention sewage treatment unit The configuration diagram is shown.

1 to 3, the smart water treatment system using storm water and storm water according to an embodiment of the present invention is the storm drain 10, the storm drain 20, the sewage treatment unit 30 and concentrated remote It comprises a supervisory control and data acquisition (SCADA) (40).

The rainwater drainage part 10 collects rainwater from a roof or a roof of a building, and as shown in FIG. 2, a water collecting tank 11, first and second solenoid valves 12, 12a, It comprises the 1 flowmeter 13, and is comprised.

The water collecting tank 11 collects rainwater, and the first and second solenoid valves 12 and 12a discharge the rainwater collected from the water collecting tank 11 at an initial rainfall of high concentration as shown in FIG. 5. Is connected to the sewage pipe through the second line (L2), so that only the rainfall after the initial opening and closing control by the centralized remote monitoring control system 40 to discharge to the sewage treatment unit 30 through the first line (L1). It is composed.

The first flow meter 13 is configured to check the flow rate of the rainwater discharged through the first and second lines (L1) (L2) and transfer it to the centralized remote control system 40.

In other words, the initial rainwater shows the initial contamination of chemical oxygen demand (COD) and suspended solids (SS) by washing of sedimentary sediments, but gradually decreases as rainfall continues, reaching near-water quality of about 2-4 NTU. This is because, in particular, when rainfall does not fall and the number of preceding rainfall days is long, the pollution degree in rainwater is very high, and therefore, the initial rainwater should be excluded or treated immediately upon collection.

Here, in the case of urban areas, harmful substances such as sulfurous acid gas and nitrogen oxides are dissolved in rainwater due to exhaust gas, and the catchment surface may be contaminated by algae or rodents. In order to connect the solenoid valve 12 and the first flow meter 13 to the first and second lines (L1) (L2) extending from the sump (11), respectively, and the initial rainwater of 5 mm or less discharged to the sewer pipe And, since the rainfall is applied to the method of excluding the initial rain water to be sent to the sewage treatment unit 30, which is because it can automatically block the initial rainfall and provide the advantages of easy operation and maintenance.

In other words, the household sewage excludes flush water, which is a black water, which can be collected as a single pipe when living sewage including flush water is used as raw water. This is because a large amount of bacteria or viruses are present in the wash water and the pollution degree is high, which may increase the cost of treating water and cause odors.

Accordingly, in the embodiment of the present invention, it is determined that it is economically and emotionally preferable not to use the flush water and the high concentration of domestic sewage which are black water.

For example, when cleaning food-stained dishes in the sink with detergent and when washing vegetables or fruits, etc. As such, there is a large variation in the degree of pollution of the sewage drained according to the purpose of use of the water.

In addition, even in the case of the washing drainage discharged from the washing machine, the initial washing drainage has a high organic matter concentration and a high concentration of oil components or surfactants, which requires a lot of treatment costs, but the wastewater generated in the rinsing step has a very low pollution.

Therefore, the drainage generated in the kitchen or washing machine is preferably separated and used as raw water for reuse according to the stage of use, and the drainage discharged from the sink or the bathtub occupies 10-30% of the total amount of sewage, and the water quality is also relatively high. It is good. In particular, the water drainage generated in accommodation facilities such as hotels and inns is very good in terms of quantity and water quality, so that it can be reused only by simple physical and chemical treatment.
