10. A water-saving and environment-friendly pretreatment process for yellow croaker processing. The following steps are involved: Step 1, transportation; Step 2, cleaning; Step 3, water treatment; Step 4, cleaning; It is characterized by: In the above step 1, the output of the first motor (12) drives the first roller (13) and the first conveyor belt (15) to move, and the yellow croaker to be cleaned is transported by the first conveyor belt (15). When the yellow croaker to be cleaned falls onto the transport platform (18), the output of the propulsion cylinder (16) drives the push plate (17) to move, and the yellow croaker to be cleaned is pushed into the cleaning tank (19) by the push plate (17); In the above step 2, the yellow croaker in the cleaning tank (19) is rinsed by the lower spray (20) and the upper spray (23), and the roller brush (21) is driven to move by the output of the second motor (22), and the yellow croaker is scrubbed by the roller brush (21), and the second roller (25), the second conveyor belt (26) and the conveyor plate (27) are driven to move by the output of the third motor (28), and the cleaned yellow croaker is transported to a subsequent processing location by the conveyor plate (27); In the above step 3, the sewage in the cleaning tank (19) is transported to the filter box (31) through the first water pipe (30), and the larger impurities in the sewage are filtered through the filter plate (32). The first servo motor (35) drives the first water pump (34) to work, so that the first water pump (34) transports the filtered sewage in the filter box (31) to the regulating tank (36) through the second water pipe (33), and the acid-base regulator and nutrient salts are added to the regulating tank (36) to adjust the water quality of the sewage. The output of the second servo motor (39) drives the second water pump (38) to work, so that the second water pump (38) transports the treated sewage in the regulating tank (36) through the second water pipe (33). The wastewater is transported to the biological pool (40) through the third water pipe (37), aerobic oligotrophic microorganisms are cultured in advance in the biological pool (40), and the wastewater is treated by the microorganisms. The output of the third servo motor (43) drives the third water pump (42) to work, so that the third water pump (42) transports the treated wastewater in the biological pool (40) to the sedimentation tank (44) through the fourth water pipe (41), and calcium hydroxide is added to the sedimentation tank (44). After the wastewater is precipitated, the output of the fourth servo motor (47) drives the fourth water pump (45) to work, so that the fourth water pump (45) transports the treated water back to the water supply of the production line through the fifth water pipe (46); In the above step 4, the output of the fourth motor (51) drives the connecting rod (52), the telescopic plate (54) and the cleaning brush (56) to move, and the first damper (53) and the first spring (55) cooperate to drive the telescopic plate (54) to move. The second damper (57) and the second spring (58) cooperate to make the cleaning brush (56) closely attached to the sedimentation tank (44), and the cleaning brush (56) cleans the sludge deposited in the sedimentation tank (44) and discharges it through the sewage outlet (59).
