Description

Equipment for the treatment of waste liquid using water-purifier tank}

The present invention relates to a wastewater treatment apparatus using a septic tank, and more particularly, to forcibly transfer the purified water to a septic tank for reacting and sedimenting and sedimenting the sewage and wastewater including an incoming nonpoint source. The present invention relates to a wastewater treatment apparatus using a septic tank that can improve the quality of treated water by providing a filtering device for filtering, as well as remove nitrogen and phosphorus.

In general, the lack of awareness of the importance of the environment in the course of rapid economic development is well known from the fact that the pollution, as well as the water quality, has reached a very severe level. In particular, household sewage, agricultural and livestock waste, and industrial wastewater generated in the course of human activities are contributing to pollution of public waters such as appeals, inner bays and inland seas, and small and medium urban streams.

In addition, in recent years, due to urban population concentration due to rapid industrial development, the proportion of inorganic and organic components in wastewater and wastewater is gradually increasing along with the increase of various water volumes. Such waste water contains high concentrations of organic substances such as chemical oxygen demand (COD), biochemical oxygen demand (BOD), suspended solids (SS), nitrogen and phosphorus, and flows into rivers, lakes, dams, etc. Pollution, as well as the destruction of the ecosystem due to toxicity will adversely affect the environment. Therefore, the waste water and waste water are set to a predetermined standard, and purified and drained to below a predetermined standard value.

As a conventional control technique for treating wastewater as described above, various techniques using a filter have been proposed, but most of the wastewater treatment apparatus using a filter according to the prior art simply filters the wastewater.
