摘　　要：针对海水养殖废水一次排放量大、污染物种类及结构复杂、寡营养、盐度较高等特点,采用水力筛网+连续流砂滤池+沸石吸附+活性炭吸附工艺处理某对虾人工繁育基地生产废水,稳定运行后,对CODMn、BOD5、无机氮、活性磷酸盐、SS的去除率分别达到46. 00%、35. 25%、62. 94%、84. 34%、84. 73%,处理出水的CODMn、BOD5、无机氮、活性磷酸盐、SS分别为(3. 72±0. 22)、(3. 38±0. 05)、(0. 39±0. 02)、(0. 04±0. 002)和(11. 43±0. 02) mg/L,可达到《海水养殖水排放要求》(SC/T 9103-2007)的一级标准。Mariculture wastewater usually has large amount of wastewater drainage,complex components,low nutrient concentration,and high salinity. The process of hybridmesh,continuous sand filter,zeolite adsorption and activated carbon adsorption was used to treat the wastewater from a shrimp breeding base. Results showed that the removal rates of CODMn,BOD5,inorganic nitrogen,active phosphate and SS were 46. 00%,35. 25%,62. 94%,84. 34%,84. 73%,while their concentrations were reduced to (3. 72 ± 0. 22),(3. 38 ± 0. 05),(0. 39 ± 0. 02),(0. 04 ± 0. 002),(11. 43 ± 0. 02)mg/L,respectively. Overall,the effluent quality met the primary level of Water Drainage Standard for Sea Water Mariculture (SC/T 9103-2007).
