More specifically, a plurality of cover units (10) having a predetermined width, length and thickness are consecutively placed in a widthwise direction and the front ends of cover units (100) adjacent to each other in a widthwise direction are combined to form the cover. The cover units (10) include: a body (11) including an outer wall (12) on the outside in a thickness direction, an inner wall (13) on the inside in a thickness direction, a first lateral wall (11a) at a front end on one side in a widthwise direction, a second lateral wall (11b) at a front end on the other side in a widthwise direction and a plurality of hollow parts divided by partitions; a first combination part protruding from the first lateral wall (11a) of the body (11) in a width direction as far as a predetermined length; and a second combination part (30) extended from the second lateral wall (11b) of the body (11) in a widthwise direction as far as a predetermined length to be combined with the first combination part (20). The first combination part (20) includes a first combination piece (26) having a square shape, and the second combination part (30) includes a second combination groove (33) combined with the first combination piece (26) through insertion and a second outer combination piece (31) extended from the upper part of the second lateral wall (11b) of the body (11) in a widthwise direction and including an second outer hanging piece extended inwards from the front end to be hung on a first outer hanging piece (22) of the first combination part (20) when combined with the first combination part (20) of another adjacent cover unit to prevent the second combination part (30) from being separated from the first combination part (20). 본 발명은 수처리 조의 상부 개방부를 덮도록 설치된 수처리 조의 덮개(100)에 관한 것으로, 특히 일정한 폭과 길이 및 두께를 가진 덮개 유니트(10)를 폭방향으로 복수개를 연속적으로 배치하여 서로 인접하는 덮개 유니트(100)의 폭방향 선단부들을 결합하여 구성되고, 덮개 유니트(10)는, 두께방향 외측의 외측벽(12), 두께방향 내측의 내측벽(13), 폭방향 한쪽 선단의 제1측벽(11a), 폭방향 다른 쪽 선단의 제2측벽(11b), 격벽으로 구획된 복수의 중공부를 가지는 몸체(11)와; 상기 몸체(11)의 제1측벽(11a)에서 폭방향으로 일정한 길이만큼 돌출된 제1결합부(20); 상기 몸체(11)의 제2측벽(11b)에서 폭방향으로 일정한 길이만큼 연장되어 상기 제1결합부(20)와 결합하는 제2결합부(30);를 구비하고, 상기 제1결합부(20)에는 사각형의 제1결합편(26)이 구비되고, 제2결합부(30)에는 제1결합편(26)을 끼워 결합하는 제2결합홈(33)을 구비하며, 몸체(11)의 제2측벽(11b) 상단에서 폭방향으로 연장되고, 선단에 내측을 향하여 연장되어, 인접하는 다른 덮개 유니트의 제1결합부(20)와 결합시, 제1결합부(20)의 제1외측 걸림편(22)에 걸려서, 제2결합부(30)를 제1결합부(20)에서 분리되지 않게 고정하는 제2외측 걸림편을 구비한 제2외측 결합편(31)을 구비한다.
