The innovative process consists of biological unit for wastewater treatment and ozonation unit for excess sludge treatment. An aerobic membrane bioreactor(MBR) was used to remove organics and nitrogen, and an anaerobic reactor was added to the biological unit for the release of phosphorus contained at aerobic sludge to enhance the removal of phosphorus. For the excess sludge produced in the MBR, which was fed to ozone contact column and reacted with ozone, then the ozonated sludge was returned to the MBR for further biological treatment. Experimental results showed that this process could remove organics, nitrogen and phosphorus efficiently, and the removals for COD, NH 3-N, TN and TP were 93.17%, 97.57%, 82.77% and 79.5%, respectively. Batch test indicated that the specific nitrification rate and specific denitrification rate of the MBR were 1.03 mg NH 3-N/(gMLSS·h) and 0.56 mg NOx-N/(gMLSS·h), and denitrification seems to be the rate-limiting step. Under the test conditions, the sludge concentration in the MBR was kept at 5000—6000 mg/L, and the wasted sludge was ozonated at an ozone dosage of 0.10 kgO 3/kgSS. During the experimental period of two months, no excess sludge was wasted, and a zero withdrawal of excess sludge was implemented. Through economic analysis, it was found that an additional ozonation operating cost for treatment of both wastewater and excess sludge was only 0.045 RMB Yuan(USD 0.0054)/m 3 wastewater.

Domestic wastewater was treated by combined anaerobic biofilm aerobic membrane bioreactor(MBR) process, and part biomass in MBR was withdrawn to treat with ozone, then the ozonated sludge was returned to anaerobic inlet. In aerobic MBR, MLSS and DO were controlled at 3000—3500 mg/L and 0 8 mg/L respectively. Comparing the experimental results of two stages, it was noticed that ozonation did not affect the removal efficiency for organics but had a significant influence on the removals of NH 3 N and TN. During the ozonation period of two months, no excess sludge was wasted, and a zero sludge yield was obtained.

Ectopic pregnancy is a pregnancy that occurred outside the uterus,usually in the fallopian tube,followed by other abdominal *** pregnancy could not develop normally to term and requires sufficient evaluation and intervention with medication or surgery in most cases(1).As a rare form of abdominal pregnancy(2),splenic ectopic pregnancy could be treated by drug treatment(3)or surgical interventions,including laparotomy and laparoscopy,which focused on total splenectomy(4,5).A previous study(6)indicated that laparoscopic partial splenectomy for selected patients was safe and *** to the fragile texture of the spleen,the suture method during laparoscopic partial splenectomy was technically demanding since it might encounter higher risk of splenic vascular hemorrhage than total ***,few reports focused on the treatment of splenic ectopic pregnancy via laparoscopic partial splenectomy(7).In order to avoid the potential severe complications such as hemoperitoneum(8)caused by drug treatment alone,and to avert impaired hematopoietic and immune function caused by total splenectomy,we herein presented a case(Video 1)of a 30-year-old woman(gravida 2,para 1)undergoing laparoscopic partial splenectomy performed by hepatobiliary surgeons to treat splenic ectopic pregnancy.
