Description

Recycling system of rain water

The present invention relates to an abattoir recycling system, and more particularly, to an abattoir recycling system comprising an initial exclusion exclusion device (20) for reusing water by ecologically treating rainwater, and a stormwater treatment device (60) And a backwash mode in which the treatment filter is automatically cleaned in accordance with the filter condition.

Recently, rainfall patterns are concentrated in specific periods due to climate change. Therefore, measures to prevent flood damage are urgently needed. As the amount of water available due to frequent droughts and water pollution is decreasing, Is expected to be further intensified, but the technology to cope with this is insignificant. Therefore, it is urgently required to develop a water reuse technology that can reuse rainwater or wastewater treated water for landscape water, hydrophilic water, industrial water, and urban reclaimed water.

In order to solve this problem, a conventional water reuse apparatus has a structure in which sedimentation and separation of sludge are carried out by injecting coagulant into raw water to be introduced, and pollutants not treated in the pretreated treated water are discharged in a scum- And a backwash function is added. Such conventional technology has a problem in that it is inevitable to input power for injecting a drug, the process is complicated, and can act as a secondary pollutant source of effluent water due to chemical injection.

The above-described technology adopts the advanced oxidation method and is equipped with the flotation plant purification device, which is an environmentally friendly technology. However, ozone air supply is applied as a reverse rinse process and an advanced oxidation means, so care must be taken in operational management. As the flotation plant purification means is applied, a separate alternative for the maintenance of flotation plants in the winter season is required.

Another prior art is a technique for removing residual contaminants by biological treatment with microorganisms. However, this method is difficult to obtain the expected effect of pollutant treatment in a place where the concentration of heavy rainfall is high, the load fluctuation is rapidly changed, the range of nonpoint pollutant sources and emission characteristics are wide and temporarily concentrated like in Korea, It takes a long time to do so, which leads to considerable problems in the field application.
