Description

Filtering apparatus for rainwater treating

The present invention relates to a filtering device for treating foreign matter contained in rainwater, and more particularly, to remove pollutants in the form of particles contained in rainwater, and to use it as a filtering device for rainwater reuse, or to treat rainwater. The present invention relates to a filtration device for treating rainwater that can be used as a filtration device that is a pretreatment facility of an abatement facility.

Generally, the filtering device for stormwater treatment is used as a pretreatment facility for supplying filtered rainwater to a facility that reuses rainwater in homes, schools, public facilities, etc. (hereinafter, referred to as a "traditional rainwater reuse facility"), or It is used as a pretreatment facility for a nonpoint source reduction facility to improve the treatment efficiency of a nonpoint source reduction facility.

First, a conventional rainwater reuse facility refers to a facility that makes rainwater storage tanks such as rainwater storage tanks at homes, schools, and public facilities, stores rainwater, and utilizes the stored water as living water, landscape water, and fire water. In addition, the rainwater storage tank stores rainwater in which rainwater collected from buildings is not directly introduced, but once filtered, and foreign matters are removed. Therefore, the lower part of the rainwater collecting pipe for collecting rainwater from the building is provided with a filtration device for storm water treatment connected to the rainwater storage tank.

Therefore, a description of the "rainwater recycling system" of the Republic of Korea Utility Model Publication No. 2017-0002022 as an example of the conventional rainwater reuse system as follows.

Conventional rainwater recycling system is connected to the rainwater collecting pipe for collecting rainwater, the rainwater collecting pipe is connected, the initial excellent storage tank for selectively storing the initial rainwater, and branched to communicate with the initial excellent water collecting pipe When the inside of the initial excellent storage tank is filled with the initial excellent rain coupled to the rainwater inlet pipe to separate and collect the subsequent rainwater, and connected to communicate with the rainwater inlet pipe, included in the rainwater introduced through the rainwater inlet pipe It comprises a filter for filtering the discharged foreign matter after filtering the foreign matter.

The filter is provided with a housing in which a space is formed therein, and a primary filtration filter formed in a mesh net form to filter out foreign substances and discharge rainwater naturally, and provided in a lower portion of the primary filtration filter in the rainwater. The secondary filtration filter is provided with a plurality of activated carbon inside the filter net so that heavy metals, chemicals, and contaminants contained therein can be removed by adsorption.

However, in the case of using the conventional rainwater recycling system configured as described above, as the foreign matter sinking in the water flows directly into the rainwater storage tank through the primary filtration filter and the secondary filtration filter, it sinks in the storage tank. The foreign matter was put together, the water filled in the storage tank had a problem that is contaminated by the foreign matter sinking in the water.

In addition, in the conventional rainwater recycling system, foreign particles having large particles contained in rainwater are introduced into the upper part of the primary filtration filter of the filter, and then filtered, and foreign substances filtered by the upper part of the primary filtration filter are discharged to the ground outside of the filter through the foreign substance outlet. As a result, the periphery of the filter also had a problem of environmental pollution, which is polluted by foreign matter discharged from the filter.

In addition, the conventional non-point source reduction facility installed a pretreatment for the simple sedimentation effect, but the effective treatment was difficult due to the turbulence generated by the fall of the structure, the disturbance of the sedimentation due to the stagnation of the treated water due to the non-power treatment process. Therefore, in order to solve this problem in some of the conventional non-point source reduction facilities, a rainwater recycling facility consisting of a simple screen has been installed as a pretreatment facility.

However, when the rainwater recycling facility consisting of a simple screen is installed as a pretreatment facility of the conventional nonpoint source reduction facility, the treatment efficiency of the conventional nonpoint pollution reduction facility is improved by obtaining only the filtration effect by the simple screen in the rainwater recycling facility. Had problems falling.
