Description

Draining unit for purifying the non-point pollution source in rainwater}

The present invention relates to a device for collecting and purifying non-point contaminants in order to prevent water pollution due to rainfall and to secure water resources, and to collect rainwater mixed with non-point contaminants to properly treat various pollutants. The present invention relates to a non-point contaminant treatment device included in rainwater that can prevent contamination of water quality and soil, and can easily exchange screens and filtration adsorption networks for filtering pollutants, and is easy to maintain and repair. .

Generally, water pollution sources include point pollution sources and non-point pollution sources. Point sources and nonpoint sources are a relative concept. For example, factories that discharge plant wastewater collected through conduits and treated through water pollution prevention facilities are point sources, and runoff flows into rivers without treatment. Factory sites, such as dumping sites, are non-point sources. Non-point pollution includes fertilizers and pesticides remaining in farmland without being absorbed by crops, manure from livestock grazing on pasture, untreated livestock waste discharged from livestock farms, air pollutants mixed with rainwater, sediments on road surfaces, and rainfall in confluent sewer pipes. There is a mix of sewage, sewage and rainwater that flows into the river beyond the city's design.

Point pollutants that are artificially discharged from factories, household sewage treatment plants, manure treatment plants, and livestock farms are discharged year-round due to less natural influences due to the fact that discharge points and discharge routes are clearly specified and concentrated into the treatment plant through conduits. As the difference between the two is constant, it is possible to predict the amount of generation year by year because the effect of the season is relatively small, so that it is easy to collect and the processing efficiency is high, so it is easy to design, maintain and manage treatment facilities such as conduits and treatment plants, Non-point pollutants, which emit unspecified water pollutants at unspecified places such as forests, mountains, and construction sites, are difficult to collect due to the inflow and outflow paths of pollutants, which are difficult to collect. It is very dependent on the design and maintenance of the treatment facility.

Types of nonpoint sources include soils, nutrients, bacteria and viruses, oils, metals, organics, pesticides, and various contaminants.

Soils are a major source of rainfall runoff, and nutrients, metals, hydrocarbons, and other contaminants are filtered and adsorbed and cause a fatal effect on the photosynthesis, respiration, growth, and reproduction of aquatic organisms.

Nutrients are nutrients such as nitrogen and phosphorus, which are used as fertilizers, and are leaked from lawns, farmland, urban roads, and sewers of houses and golf courses, and flow into the streams, thereby accelerating the growth of algae.

Bacteria and viruses are frequently detected in animal waste and sewage overflowed from sewers, and high concentrations of bacteria and viruses in rainfall effluents contaminate streams and lakes, causing closure.

Oil can be fatal to aquatic organisms, even in small amounts, and contamination occurs during accidents such as leaks, vehicle rollovers, vehicle cleaning, and dumping of wastes.

Heavy metals such as lead, zinc, cadmium, copper, and nickel are commonly detected in rainfall runoff in urban areas, and over 50% of the total amount of metals flowing into rivers is discharged through soil. These metals are fatal to the aquatic ecosystem, require special management because of the potential for bioaccumulation and contamination of drinking water.

Organic substances flow out from a wide range of places such as fields, rice fields, forests, and residential areas. Especially in confluence, organic matters contained in sewage and sewage that flow through the sewage pipes at low flow rates are usually deposited at the bottom of the conduit. In industrial areas, artificial organic compounds such as adhesives, cleaning agents, and solvents are widely used, resulting in improper storage and disposal.

Insecticides such as herbicides, pesticides, and antifungal agents can accumulate in aquatic organisms such as plankton, causing bioconcentration through the food web, which can be fatal to fish and algae.

Miscellaneous wastes may include heavy metals, pesticides, bacteria, etc., such as garbage, residues, and suspended solids generated at construction sites and workplaces. In particular, fallen leaves, grass-cut residues, animal wastes, and dumped garbage are vehicles that transport bacteria, viruses, etc. to rivers and lakes, and reduce dissolved oxygen, causing fish to die.

Non-point source has only been leaked during rainfall and it has not been recognized as a source of pollution due to the rainwater management policy. However, recently, the control of non-point source has emerged as an important environmental problem as the pollution level by non-point source has been confirmed. The impact of non-point pollution shows that land development is accelerated due to the progress of urbanization and industrialization, and the water quality impact of rivers and lakes caused by non-point sources increases due to the increase in the area of impermeable layers such as land, roads, and parking lots. Pollutants such as nutrients such as substances, nitrogen and phosphorus, and heavy metals with high concentrations are difficult to collect and treat. Therefore, they immediately enter rivers without special treatment and contaminate the water quality. Accordingly, fish may collectively die or destroy habitats of benthic organisms. In addition, when the impermeable layer increases due to land development, the amount of rainwater that is not absorbed or evaporated into the soil during rainfall increases the amount of rainwater, which increases the risk of flooding and decreases the groundwater replenishment. ) Is a factor causing.

Therefore, in order to protect the water supply and ensure the soundness of the inland water ecosystem, measures to manage point sources such as wastewater treatment facilities and sewage terminal treatment facilities must be continuously pursued, and non-point source reduction plans must be prepared from the stage of land development planning. do.

Purification of non-point pollutants is very important in terms of recycling of water resources in addition to the above-mentioned dimensions of water pollution. In addition to human daily life, most industrial activities rely heavily on water resources, and water consumption is growing exponentially with respect to population growth. This consumption situation is spreading due to water disputes between countries and regions because it may threaten human life in the future, and may cause deterioration of ecosystems and loss of biodiversity. As such, due to the nature of the modern industrial society, which requires environmental pollution and a large amount of industrial water, securing water resources is an urgent problem that will affect national competitiveness and public welfare in the future. Therefore, there is an urgent need for efficient water management, securing, and utilization as a water resource policy to solve the shortage of water resources.

The methods for recycling the waste or discharged water resources to secure scarce water resources include recycling sewage treatment effluents, using sea water, and using rainwater.

Treatment of sewage water Effluent treated by physical, chemical and biological techniques is recycled using advanced techniques such as filtering techniques, advanced oxidation techniques, and efficient disinfection techniques. It is uneconomical.

Desalination using seawater is a technique of obtaining fresh water by removing salt from seawater that is abundant on the earth, and can secure a large amount of water resources without burden such as environmental damage caused by traditional water development such as dam development. Although this is a realistic alternative in countries with limited water resources, there are many places to build pretreatment facilities, and there are economic difficulties in terms of equipment technology and maintenance.

The method of utilizing rainwater as a non-point pollutant is a method of recycling water resources because the treatment cost is low and the cost burden of the filtration treatment is small, so that purified water of high purity can be obtained with a small cost and can be used immediately for heavy water. Very efficient.

Therefore, various ways to effectively use rainwater as an efficient water management, securing and utilization method to solve the shortage of water resources have been reviewed and developed.

In order to treat nonpoint sources, various construction methods have been proposed, such as the installation of facilities such as storage type, infiltration type, and device type, and the method of planting vegetation. Most of the equipment-type facilities that can be underground at a small scale are applied.

Conventional water collection systems using rainwater contain water collection and filtration processes, but systems that are complex and require high maintenance costs as well as manufacturing costs are not economical and inefficient.

 In order to take advantage of contaminated rainwater, additional costs for removing contaminants can be increased, so that the initial rainwater washes off contaminants and then collects relatively clean rainwater. Excellent water collecting devices are required.

Rainwater, which is a nonpoint source of pollution caused by rainfall, shows temporary flooding in urban areas due to sudden heavy rains, or it enters rivers with various contaminants present on the road, increasing pollution. Measures must be taken to ensure safe collection and disposal.

In rainwater, rainwater in the early days of rainfall usually contains a large amount of dust distributed in the atmosphere, and various kinds of papers, leaves, wood chips, synthetic resins, etc., scattered on top of industrial facilities or on the roof and ground of buildings. It is accompanied by contaminants and contaminants. Rainwater, which has been excluded from this initial rainwater, is relatively good in water quality and can be used for drinking water other than drinking water.

However, it is not easy to collect rainwater efficiently in Korea, where the four seasons are clear and rainfall is concentrated in summer.

The present invention aims to provide a water that can be safely used for a variety of purposes by preventing the contamination of water resources by ensuring that the non-point source containing pollutants can be collected and filtered. .

Technical features for achieving the intended purpose of the present invention is a screen for first filtering the contaminants contained in the non-point contaminants introduced by being separated by the first plate installed in the housing, and a manhole form that can be observed from the outside An observation hole of the screen and the flow rate adjusting tank for storing and transporting non-point contaminants;

Observation holes in the form of a manhole that can be observed from the outside are formed by a second plate installed in the housing having a continuous space by a lower inlet hole formed at the bottom of the first plate of the screen and the flow adjustment tank, and the screen is installed. And an inclined plate settling tank having an inclined settling guide plate installed thereon to discharge the second treated water in which foreign matters are deposited while the first treated water moves upward to settle the foreign matters contained in the first treated water introduced from the flow rate adjusting tank;

The secondary inlet hole is formed in a continuous space with the upper inlet hole formed in the upper portion of the second plate of the inclined plate settling tank and a manhole-shaped observation hole that can be observed from the outside, and flows through the settling guide plate installed in the inclined plate settling tank. It includes a filtration adsorption network is installed to remove the micro-contaminants dissolved in the water to store the tertiary treated water from which the foreign matters of the secondary treatment water is removed and then slowly discharged to the discharge pipe; It is a technical feature.

The screen and the flow adjusting tank are installed on the inner wall of the housing of the supply pipe into which the non-point contaminants enter, dispersing the rainwater flowing into the screen, allowing the falling water to be evenly distributed on the screen. Divided into proper size so that a plurality of them are installed.

In the screen and the flow rate adjustment tank, the screen fixing plate to which the screen is fixed is formed at a position higher than the settling guide plate and the overflow pipe of the inclined plate settling tank, and guide rails are formed to slide both ends of the screen, and the screen is formed on the guide rail. The space that is open to seat the space, and the separation prevention piece for preventing the separation of the screen located in the space is rotatably fixed to the fixed shaft.

In addition, a bypass pipe connected to the discharge pipe of the filtration adsorption and discharge tank is formed in the upper space where the screen is installed so that the rainwater flowing in rapidly can be discharged automatically.

The inclined plate settling tank is formed in a space separated by the first plate and the second plate, and forms a continuous space with the screen flow adjusting tank by a lower inlet hole formed at the lower end of the first plate, thereby removing contaminants from the screen and the flow adjusting tank. The first filtered treatment water flows in, and a sedimentation induction plate is formed to guide the flow of the first treatment water flowing therein to precipitate the contaminants passing through the screen, and then through the upper inlet hole formed in the second partition wall. The precipitated secondary treated water can be naturally transported to the filtration adsorption and discharge tank.

The sedimentation guide plate has a lower settling guide plate installed on the bottom surface and a fixed-bed media to naturally send the contaminants to the screen and the flow adjusting tank while guiding the first treatment water to the lower inlet hole of the first plate. It consists of an upper settling guide plate which is formed in an intermediate part and precipitates contaminants contained in floating water in a time delayed manner following collision and friction.

The upper inlet hole formed in the upper settling guide plate and the second plate is installed at a lower position than the screen to prevent the occurrence of rainwater flowing over the bypass pipe from the screen and the flow adjustment tank to the maximum, thereby improving the filtration treatment efficiency. .

Contaminants are guided to the lower slope guide plate and recovered to the screen and flow control tank.

This sedimentation guide plate is able to settle the contaminants in the sedimentary particles and then send them to the screen and the flow control tank to reduce the filtration load of the continuous filtration network in the filtration adsorption and discharge tank to extend the life of the filtration network Easy maintenance management.

 Secondary treatment water, which is filtered through the settling guide plate, the foreign matter is filtered through the upper inlet hole formed in the second plate when the water level is above a certain level and flows into the filtration adsorption and discharge tank.

The tertiary treated water is slowly discharged through the discharge pipe when the water level is over a certain level.

The non-point source treatment apparatus of the present invention includes a screen flow adjustment tank for removing contaminants contained in a large amount of rainwater initially introduced, an inclined plate settling tank for depositing and recovering contaminants, and filtration adsorption for filtering fine contaminants. The drainage tank is constructed sequentially to collect and store the rainwater flowing through the screen, and then filter the fine contaminants contained in the nonpoint pollutants before being discharged into the river by the stepwise treatment of the nonpoint pollutants. In case of non-point pollutant inflow due to unexpected heavy rain such as guerrilla heavy rain, the inflow rate is lowered and distributed evenly in the storage tank while being distributed evenly, and the filtration process is performed sequentially. It can prevent flow with drainage.

In addition, according to the present invention, even when a large amount of road drainage flows in and flows in, the road drainage is uniformly distributed and flows through the filter, thereby effectively removing contaminants contained in the road drainage, thereby removing pollutants. Large amounts of nonpoint sources can be collected and treated.
