The phosphorus removal experiment implies the increasing 100 mg/L MLSS concentrations can remove about 1 mg/L TP. The phosphorus removal efficiency can be improved by the increasing rate of MLSS concentrations. When everyday increasing rate of MLSS concentrations are about 500mg/L, the phosphorus removal efficiency would higher than 90%, effluent TP would be lower than 1 mg/L. When MLSS concentrations are fluctuating, effluent phosphorus would fluctuate correspondingly. Everyday the amount of discharging excess sludge can be prejudged by the amount of influent TP.

通过对反应器的除效果的研究,发现污泥浓度增长100 mg/L能去除将近1 mg/L TP;发现随着污泥浓度增长速率的增加,除效率相应提高;当污泥浓度的增长速率增加到每天500 mg/L时,的去除率将高于90%,并且出水TP浓度将低于1 mg/L;发现每天排放的剩余污泥量可以根据进水TP浓度来决定;发现最佳好氧与厌氧时间比T_是0.5;溶解氧冲击指数DO_I被首次提出,作为分析溶解氧DO影响的指标。

The supported WP catalysts showed considerable activity in HDS reaction of dibenzothiophene and HDN reaction of quinoline. The ibenzothiophene HDS activity and quinoline HDN activity of the spported WP catalysts synthesized by co-impregnation method was better than that synthesized by mixing method. The HDS and HDN activities of 25~30% WP catalysts synthesized by co-impregnation method and reduced at 650~750℃ were better than those of the corresponding sulfurized catalyst.

负载型WP催化剂具有较好的二苯并噻吩加氢脱硫和喹啉加氢脱氮活性,共浸渍法制备的化钨催化剂二苯并噻吩加氢脱硫和喹啉加氢脱氮活性要高于混合法制备的化钨催化剂。650~750℃还原制备的负载量25~30%的浸渍法化钨催化剂具有较高的二苯并噻吩加氢脱硫和喹啉加氢脱氮活性,高于相应的硫化态催化剂。

Using tamato seedlings as experimental material, we examined the adaptive changes of the proton translocating pumps and protein components in vacuolar membranes of plant during phosphate starvation.

The effects of magnetic seed, aluminum sulphate and pH value on phosphorus adsorption, precipitation and coagulation were surveyed. The results made it clear that Al ion as precipitant and coagulant was the main effect factor on P removal; as adsorbent magnetic seed had little effect on P removal, but made the phosphate precipitate sink faster; pH value had effect on both precipitation and adsorption.

研究了磁种、硫酸铝、pH值等对的吸附、沉淀、凝聚的影响,结果表明:铝离子的沉淀作用是除的主要原因;磁种的吸附作用对除的贡献较小,但使酸盐沉淀物的沉降性能大大提高;pH值既影响沉淀作用,也影响吸附作用。

It is found that the structure of the ternary electroless Ni-W-P coating is greatly influenced by W content in the deposit. It is also found that the requisite content of phosphorus for amorphous Ni-W-P structure is less than that of Ni-P binary alloy coating, and the more tungsten exists, the less phosphorus is required. The hardness of the deposits will be enhanced as the deposit structures are changed from amorphous to mix-or nanocrystalline structures. The corrosion resistance of Ni-W-P ternary alloy is improved as W content increased, and the passivation of amorphous deposits is formed more easily than that of mix-structure and nanocrystalline deposits.

研究发现,化学镀Ni-W-P三元合金镀层的结构受镀层中钨含量的影响较大,非晶态Ni-W-P三元合金镀层所需含量较非晶态Ni-P二元镀层所需含量要低,并且钨含量越高,所需含量越少;镀层硬度随镀层结构从非晶态→混晶态→纳米晶态转变而增加;镀层的耐蚀性随镀层中钨含量增加而变好,且非晶态镀层较混晶态和纳米晶态镀层更易形成钝化区。
