    The main work of this article is to determine the treatment process and design parameters by researching the character of the wastewater and the treatment process home and abroad of fishery manufacture wastewater, The main difficulties of fishery manufacturing wastewater are:high density of suspended solids and animal grease in wastewater;high density of NH_(3-)N and phosphate; The sludge is colloidal, difficut to dewater, and the quantity of sludge is large.Based on the analyzing comparation, elected wastewater treatment process is as following: preliminary sedimentation + equalizing + coagulation and flotation+A~2/O. The sludge treating process is sludge concentrating to stabilize phosphate + equalizing +mechanical dewatering. In the operation of this process, the average density of CODcr of inlet is 1900 mg/L,NH4-N is 105 mg/L, phosphate is 10,and animal grease is 80, SS is 600; the average density of CODcr of output is 83mg/L,the removal rate is 88.7%, the average density of NH4-N of output is 18, the removal rate is 82.8%, the average density of phosphate of output is 0.8, the removal rate is 92.0%, the average density of animal grease of output is 4.0, the removal rate is 95%, the average density of SS is 100 mg/L, the removal rate is 83.3%.The results show that the process is feasible for this project either on technique or economy.

    Objective:The optical environmental condition for removing-ammonia-nitrogen from fishery process wastewater by Ctdorella vulgaris would be determined,and the foundational experimental data would be provided for disposing this kind of wastewater by it in scale-up.Meth- ods:Under the mode of stationary shake-flask culture,the initial pH of the mixture of wastewater and Chlorella vulgaris culture,temperature and light strength were changed one by one,the Content of ammonia-nitrogen in the mixture was determined in a fixed period,so the optical en- vironmental condition could be concluded as culture time varied.Results:When the initial concentration of C.vulgar/s culture was 1×10~6 cells/ mL and the rational ratio of C.vulgaris culturing medium and wastewater was 3:2,the optimal environmental condition for removing ammonia- nitrogen by C.vulgaris was followed:pH=7.5,25℃,the light period of 12 hours,and the light strength of 5 300 lx,at this condition,the re- moval rate of ammonia-nitrogen was up to 77 %.Conclusion:C.vulgaris could remove ammonia-nitrogen from fishery process wastewater in optical experimental condition,and some foundational experimental data would be provided for disposing this kind of wastewater by Chlorella vul- garis in scale-up.
