The present invention relates to a black soldier fly larva selection and dehydration system using a washing water circulation method which completely separates black soldier fly larvae and fecal soil by mixing washing water with a mixture of black soldier fly larvae and fecal soil with a high moisture content and dehydrates and discharges black soldier fly larvae wet with washing water. The black soldier fly larva selection and dehydration system using a washing water circulation method comprises: a first water tank in which washing water is supplied and stored; a second water tank in which a mixture of black soldier fly larvae and fecal soil is added and the washing water is supplied from the first tank, and the mixture and the washing water are stirred to form a mixed solution; a first dehydration device which separates the mixed solution supplied from the second water tank by a first pump into the washing water and the wet black soldier fly larvae, and supplies the washing water separated from the mixed solution by a second pump to the first water tank; and a second dehydration device which dehydrates the wet black soldier fly larvae supplied from the first dehydration device and discharges the dehydrated black soldier fly larvae. Accordingly, the purity of selection of the black soldier fly larvae and the fecal soil can be greatly improved. 본 발명은 동애등에 유충과 함수율이 높은 분변토의 혼합물에 세척수를 혼합하여 동애등에 유충과 분변토를 완전히 분리하고 세척수로 인하여 젖은 상태의 동애등에 유충을 탈수하여 배출하는 세척수 순환방식의 동애등에 유충 선별 및 탈수 시스템에 관한 것으로 세척수가 공급되어 저장되는 제 1수조, 동애등에 유충과 분변토의 혼합물이 투입되고 상기 제 1수조로부터 세척수가 공급되며 상기 혼합물과 세척수를 교반하여 혼합액을 형성하는 제 2수조, 제 1펌프에 의하여 상기 제 2수조로부터 공급된 상기 혼합액을 세척수와 젖은 상태의 동애등에 유충으로 분리하고 제 2펌프에 의하여 상기 혼합액으로부터 분리된 세척수를 상기 제 1수조로 공급하는 제 1탈수장치 및 상기 제 1탈수장치로부터 공급된 젖은 상태의 동애등에 유충을 탈수하여 탈수된 동애등에 유충을 배출하는 제 2탈수장치를 포함한다.
