The technological experiments of dephosphorization of the C-saturated medium ferrochromium Cr (≈ 10％)- Fe- Csat- P(≈ 0.1％) with halide flux were performed.

通过各种脱磷剂对Cr(≈10％)FeCsatP(≈0.1％)中铬铁水进行氧化脱磷实验，测定了金属中随时间变化及实验渣系的脱磷率。

The results showed that compared with traditional fluorite and phosphorous slag, phosphorous slag composite mineralizer was effective on reducing amount of f-CaO in cement clinker and improving burnablity of raw meals, but the effect was still obvious when sintering temperature and sintering time were increasing. The analysis of XRD, SEM and petrographic structure showed that phosphorous slag composite mineralizer decreased viscosity of liquid, promotes the formation of Alite in clinker and improves crystal form and size of minerals.

结果表明，与传统的萤石和磷渣矿化剂相比，磷渣与萤石复合的矿化剂可有效降低水泥熟料中游离氧化钙的含量，改善生料的易烧性；在燃烧温度与时间增加的情况下，改善作用仍然明显；通过XRD、SEM与岩相结构分析表明，磷渣与萤石的复合矿化剂降低了液相的粘度，促进了A矿的生长，对矿物的结晶形态有改善作用，有利于晶体尺寸的生长发育。

The influence factors on decomposition efficiency, such as digestion time and pH were identified. It was shown that non-condensed phosphate could be decomposed completely by persulphate.

结果表明：在碱性条件下过二硫酸钾高温氧化可使海水中非聚磷类化合物完全回收，而聚磷类化合物回收率不高，延长消化时间聚磷类化合物的回收率有一定提高。

The influence factors on decomposition efficiency, such as digestion time and pH were identified. It was shown that non-condensed phosphate could be decomposed completely by persulphate. But in alkali condition, condensed phosphate can only be decomposed partly.

By injecting commercially pure argon to make pressure in furnace up to 66.66 kPa and controlling refining temperature between 1 450 ℃ to 1 500 ℃, adding Mg-Ca alloy 50 kg/t and fluxed additions CaF\-2 11 kg/t, after refining the phosphorus content in steel 00Cr18Ni10 further decreased to (50～60)×10 -6, and oxygen and sulphur content in steel decreased to (4～6)×10 -6 and 15×10 -6 respectively.

采用CaC2 CaF2 法脱磷容易增碳，使后期冶炼工艺复杂，因此最好在吹氧前使用；CaC2 CaF2 也可用作喷吹SiCa粉脱磷时的覆盖渣，可起到保持还原气氛的作用。SiCa CaF2 法是唯一在工业规模上有少量应用的还原脱磷法，而且氧化脱除增加的硅比较容易。

It should be dirty water It is the oxidize aeration pot and biological chooser of DE model main to handle to building this, is disgusted, oxygen pool and hole type.

处理构筑物主要有平流沉砂池、DE型氧化沟、二沉池等，其主要构筑物DE型氧化沟系统是在DE型氧化沟基础上发展起来的，有2个平行的氧化沟和一个独立的沉淀池组成，处理程度大大提高，该系统可进行硝化，反硝化反应，从而达到生物脱氮的功能，在其系统前增设厌氧池则可达到除磷的目的。该系统具有高效，节能的特点，且耐冲击负荷高，出水水质好。

Weither it related to highest content of magnesium oxide and best activated effect of RP13 is still need to be further studied.

说明磷矿粉的活化效果与其结构中的伴生矿物的种类及含量存在一定的关系。13号磷矿粉的伴生矿物中含有其它磷矿粉所不含有的金云母KMg_3[Si_3AlO_(10]_2，这是否与其氧化镁含量最高、活化效果最好有关，有待于进一步研究。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
