摘要：
The present invention relates to a bio-filtering apparatus and a bio-filtering system for fish farm culture water used for purifying culture water discharged from a fish farm on the ground. The organic matter contained in the culture water is removed by a bead where a microorganism accommodated in an inner space of a bio-filtering water tank is deposited and the solid which cannot be removed by the microorganism is suctioned with the culture water by means of a solid separator provided on one side of the bio-filtering water tank. Then, the solid is naturally precipitated in the solid separator and is discharged out of the bio-filtering water tank with a small amount of the culture water to be concentrated by a solid concentrator. The filtered culture water from which the solid is separated is suctioned in the direction opposite to the direction in which the solid is precipitated in the solid separator so as to be discharged out of the bio-filtering water tank. According to the present invention, the culture water biologically-filtered by the microorganism is suctioned by the solid separator so that the solid such as the ash contained in the culture water can be removed； water pollution attributable to solid drain can be addressed； and culture fish diseases and kill resulting from the formation of an excessive amount of inorganic solid can be prevented even in a case where the solid-removed filtered culture water is reused in the fish farm because the inorganic solid is rarely contained in the reused filtered culture water.본 발명은 육상의 양식장에서 배출된 사육수의 수질을 정화하기 위한 양식장 사육수의 생물여과장치 및 생물여과시스템에 관한 것으로서, 생물여과수조의 내부공간에 수용된 미생물이 증착된 비드에 의하여 사육수에 포함된 유기물이 제거되고, 미생물에 의하여 제거되지 못하는 고형물은 생물여과수조의 일측에 구비된 고형물 분리기로 사육수와 함께 흡입된 이후, 고형물 분리기의 내부에서 고형물은 자연침전되어 소량의 사육수와 함께 생물여과수조의 외부로 반출되어 고형물 농축기에 의하여 농축되고, 고형물이 분리된 여과된 사육수는 고형물 분리기의 내부에서 고형물의 침전방향과는 반대방향으로 흡입되어 생물여과수조의 외부로 반출될 수 있도록 구성되는 양식장 사육수의 생물여과장치 및 생물여과시스템에 관한 것이다.또한 본 발명은 미생물에 의하여 생물여과된 사육수를 고형물 분리기에 흡입시켜 사육수에 포함된 회분과 같은 고형물을 제거할
