Description

Technical Field [0001] The present invention relates to an integrated rainwater treatment system using a screw filter,

The present invention relates to a collecting, storage, filtration integrated rainwater treatment system using a screw filter and a method of operation thereof. More particularly, the present invention relates to an apparatus for reusing rainwater by improving the quality of rainwater by integrally constructing a rainwater collecting apparatus, a storage apparatus, and a filtering apparatus.

Since ancient times, Korea has been known as a good mountain and good water source, and it has been recognized that water resources are abundant, but Korea is now classified as a water shortage country.

The average annual precipitation in Korea is about 1,300mm, which is much larger than the average of 880mm in the whole earth, but we are living with worry about water every year. This is because rain is concentrated in the summer, and in most areas except Ulleungdo, rainfall over three months in summer exceeds half of the amount of rainfall in a year. Even on some days there is a month's worth of rainfall.

Korea's stratum has been increasingly used every year since 1965 even under conditions where the natural topography is poor due to its thin surface layer. In particular, the use of domestic water has increased 32 times, Given the increase in population and the amount of water needed for industrial development and agriculture, it is obvious that the water shortage will become severe.

Therefore, it is necessary to construct a multi-purpose dam that can collect rainfall concentrated in the summer to increase supply in preparation for water shortage. However, it is very difficult to construct a dam for water conservation because it is difficult to select a region. The development cost is also increasing exponentially, making it difficult to implement water supply development policies on a supply-side basis.

Even though the increase in the cost of dam construction can be compensated by raising the value of the water supply, there is no solution to the damage caused by the construction of the dam. In order to fundamentally solve this problem, Water conservation efforts through government or environmental organizations will need to be made.

On the other hand, there is a need to actively introduce the concept of Wastewater Reclamation and Reusing System in the future, and a method of reducing the amount of water resources required by constructing a rainwater recycling system by city or region is more comprehensive approach It seems to be a good alternative.

However, even if the concept of water depth or rainwater recycling is introduced, it is anticipated that it will be difficult to introduce it immediately, considering the enormous cost of installing separate piping from the existing water and sewage pipes for collection and transportation. It is necessary to establish a policy plan to set up the concept of recycling of heavy water and rainwater as a long-term countermeasure and to establish a step-by-step plan to spread it to general households, preferentially to business buildings, manufacturing plants, and some areas.

In addition, underground low rain storm reservoirs are designed to store rainwater underground and use it effectively when needed. The stored rainwater has the effect of preventing the purification of the river and the natural waters caused by the reduction of the groundwater to the ground water as well as the use of the green water, the water of the toilet, the emergency water for the disaster,

However, in the conventional underground low-rainfall storm reservoir, most of the rainwater contaminated with mud or the like as in Patent No. 10-1003526 is collected and stored without being purified separately. However, since the contaminated rainwater is stored as it is, it is difficult to recycle the rainwater. Also, mud is deposited inside the storage tank, which makes it difficult to manage the storage tank.

In addition, the conventional rainwater utilization facility structure is constructed such that the water collecting device, the storage device, and the filtration device are formed separately from each other. That is, the apparatus for reusing rainwater collects rainwater on a roof or a roof, collects sludge and leaves, collects water to remove stenoses such as other foreign substances, a storage device capable of storing collected rainwater for a certain period of time, And a filtration device for securing the quality of water suited to the water used for the purpose of removing foreign matters mixed in the rainwater.

However, when the water collecting device, the storage device, and the filtration device are individually installed, it is difficult to secure the installation site and the cost increases.

Accordingly, there is a need for an integrated rainwater treatment system capable of efficiently collecting rainwater by collecting rainwater collecting devices, storage devices, and filtration devices, thereby reducing costs.
