A process for treating the sludge generated by alumina sewage treating system incldues such steps as pumping the alumina sewage in sand depositing pool then in depositing pool, mixing the bottom sludge, the sewage from sand-water separator, and the regenerated water from filter to obtain backflush water, heating in desilicating heater, washing the secondary red mud to recover Na2O and Al2O3, anjd returning the washing liquid containing Na2O and Al2O3 back to the flow of production of alumina.

本发明公开了一种氧化铝废水处理系统的污泥处置新工艺，它将氧化铝废水先进入沉砂池中进行沉砂处理后才进入沉淀池中，将虹吸泥机从沉淀池中吸出的底流污泥和砂水分离器分离出的污水以及将部分经过滤器过滤后所得的再生水作为反冲洗水一起通过污泥泵送到脱硅加热器中加热得污泥热水，然后将污泥热水用于二赤泥洗涤沉降，以回收赤泥附着的Na2O和Al2O3，将洗涤赤泥后含有Na2O和Al2O3的洗液送到氧化铝生产流程中重新使用。

Despite the cool weather, a steady stream of vehicles is keeping her washers and rinsers busy. Vincent, 15, climbs inside the bed of a monstrous white truck, soapy sponge in hand. Micah, 17, hoses off a black Mercedes.

In the experiment, three thawing methods, such as washing by water at 40℃, exposing at the room temperature of 25℃, and washing by tap water were used to estimate the effects of thawing methods on the survival rate after cryopreservation. The results showed that the relative survival rate of the calli with proembryos was higher than that of the general calli; and that different thawing methods had the same effect on the survival rate of longan calli by cryopreservation.

STUDENT:"The mowing related back to the Australian dream, the quarter acre block and how everyone would get up on a Saturday morning, go out there mow the lawn, then wash the car, then take the family for a drive down the coast in their Holden sedan, stop off at the shop for a pie for lunch, see some kangaroos and return back home and do more of the same on Sunday."

objective to evaluate clinical effect of the handling protaper nickel-titanium rotary instruments in preparation of canals of posterior teeth.methods 96teeth with pulpitis or periapical periodontitis were instrumented by handling protaper rotary instruments using step-down technique,and by k files using step-back technique for control.all teeth were obturated with lateral condensation methods.the efficiency of preparation was analyzed with ra-diographs before and after operation.results no transportation,apical blockage and ledge were found in test.the technique could keep canals smooth.there were two ledge,one instrument fracture and nine transportation in control.the operative time was shorter and post treatment pain seldom occurred in handling protaper group.conclusion the handling protaper niti rotary instruments can prepare the canals effectively and safety.after the preparation,the canals could be easily washed,sterilized and filled.it is an efficient instrumentation method for posterior teeth's canals and be used widely.

目的 评价手用protaper预备后牙根管的临床效果。方法选取患有牙髓炎和根尖周炎的后牙96例，随机分成试验组和对照组各48例，试验组用手用protaper多锥度镍钛旋转器械逐步伸入法预备根管，对照组用k锉，逐步后退法预备根管，两组均用侧向加压充填法充填根管，根据治疗前后的x线片，评价后牙根管预备效果。结果试验组无根管偏移、根尖阻塞、台阶，且根管壁平滑流畅，无器械折断等并发症发生。对照组有2例台阶形成，器械折断1例，根管偏移9例。试验组操作时间短且术后疼痛轻微。结论应用手用protaper预备后牙根管快速、安全，成形效果好，易于根管冲洗消毒及填充，可视为临床上预备后牙根管的有效方法。
