Description

[0001] The present invention relates to an initial rainwater treatment system using a squeezing device,

The present invention relates to an early stormwater treatment system using a compression device, and more particularly to a sewage pipe for introducing stormwater into stormwater, A sedimentation tank for discharging sludge separated rainwater through a discharge pipe, a treated water in the settling tank is injected into a filtration sponge through a quantitative distribution pipe, compressed by a compression device having a hexagonal honeycomb structure, And a separation tank for discharging the treated water, which has been processed in the filtration tank, with a partition wall structure provided therein and discharging the treated water to the outside, thereby simplifying and reducing the initial sludge and disinfection treatment.

Water pollution problems have occurred in many countries due to increasing population, industrialization and urbanization, water pollution due to global population increase, increase of living standards, and Korea has been classified as a water shortage country since 1993. As a result, there has been a growing interest in methods for securing water, and the method of storing and using rainwater discharged into the water system immediately when it rains can acquire water without damaging the natural environment. Interest is growing. However, there is a problem in that the method of storing and using the above rainwater is contaminated by the pollutants in the early storm, which is difficult to use without removing pollutants.

According to Article 10 of the Enforcement Decree of the Promotion and Support of Reuse of Water, the roof area is more than 1,000 square meters, the athletic facilities (only when there is a playground roof), the public office facilities, There are regulations stipulating the installation of rainwater facilities such as houses (apartments, multi-family houses, multi-family houses), schools with more than 5,000㎡, golf courses with more than 100,000㎡, and large-scale stores.

On the other hand, since most of the contaminated initial storms are not purified and simply used after being stored, the frequency of excellent utilization is low. In the case of discharging without reuse, the rainwater containing pollutants is actually the main nonpoint source, The decrease of the utilization frequency and the deterioration of water quality are caused by the rainfall. Therefore, it is difficult to predict and quantify the amount of emission depending on the period, and it is influenced by weather conditions, geology and terrain And there is no systematic standard for emission control.

According to the 'Nonpoint Source Research Service' for the upper stream of the Palang Dam in the Han River Water Source, the total generated load (BOD standard) of 169,702 tons / year as of the end of 1999 was generated in the spot pollution sources such as domestic sewage, industrial wastewater, The pollutant load of 80.4% was 130,650 tons / year. The pollutant load of nonpoint pollutant was 19,3%, which was 31,313 tons / year. The total discharge load (BOD standard) 44.5%, and it is estimated that non - point pollution sources have a significant influence on water pollution, and the Geum River, Nakdong River, and Youngsan River in the 4th water system are similar.

Prior art related to the apparatus and system for storing and purifying the initial storm is an excellent collecting apparatus excluding the initial storm of Korean Registered Patent No. 10-1222885 (Jan. 17, 2013). The apparatus is formed into a rectangular box shape extending in forward and backward directions, The upper part of the front surface is formed with an inflow port through which rainwater collects, and an upper part of the rear surface is formed with an outlet for discharging rainwater filtered for recycling. And a bottom of the filtration tank, and two sponge filters and an intermediate activated carbon filter therebetween, the bottom of which is divided into three spaces, that is, a silt sink, a suspended solids separation tank and a filtration tank, A filter layer and an initial storm vent formed through the bottom of the silt bath; An opening / closing plate for covering the inlet of the initial storm dew outlet by a hinge formed on the upper surface of the opening / closing plate and a boule formed to float on the water by weight, and an upper surface of the opening / closing plate is fixedly connected to the boule, And an opening for discharging the rainwater and opening the plate so that the hinge rotates so that the opening and closing plate covers the opening of the initial storm drain.
