酸处理

The results show that bioleached sludge at pH 3.5～1.95 can be used successfully as inoculums for the next batch bioleaching trial with the similar bioleaching efficiency,by which pH of the treated sludge can be reduced to less than 2 within 5 days for hydraulic residence time of bioleaching.

结果表明，用淋滤过程中pH3.5～1.95的生物酸化污泥作菌种，污泥的pH值都能够下降到2.0以下，而且不同pH值的生物酸化污泥作菌种的淋滤效果差异并不显著，说明淋滤过程中pH在3.5以下的污泥都可以作为菌种，接入到下一批次待处理的污泥中进行生物淋滤。

Through research and analysis of data, it was observed that the length and width of bark fiber varied according to the lop and age, the results show the fiber of the Salix bark is longer than the Salix and width of fiber almost same, fiber length of the Salix bark mainly influenced by the times of lop. The ash in Salix bark,1% Sodium Hydroxide Solubility in Salix bark, water solubility in Salix bark, Ethanol-Toluene in Salix bark, acid-insoluble lignin in Salix bark changed with the lop and age is also been investigated, the component of Salix bark is higher than Salix except acid-insoluble lignin,and it's high effected by times of lop; the TG analysis and DSC analysis is been used on the Salix bark and Salix to study the character of the hot-action, and the rang of the pyrogenate temperature is confirm; the quantity of Salix bark effect on the MOR, MOE, swelling in 24h water, nail withdraw and inner strength was determined, the results show that the Salix bark notability effect on the properties of board and dropped it; the properties of the Salix bark board is nearly the board product by other bark residues, it was established the multi regression equation of each properties and optimized the fitting produce condition of Salix bark board.

通过试验和数据处理，得出了沙柳树皮纤维长度、宽度随平茬和材龄的变化规律，结果表明沙柳树皮长度要比沙柳材的要长，宽度基本相同，沙柳树皮纤维长度主要受平茬次数的影响；找出了沙柳树皮中灰分、冷热水抽出物为、1%NaOH抽出物为，甲苯乙醇抽出物、酸不溶木素与平茬次数和材龄之间的关系，除酸不溶木素外，其他成分均明显高于沙柳材，沙柳树皮的化学成分主要受平茬次数的影响；利用TG和DSC法分析了沙柳树皮和沙柳材的反应热特征，确定了热解的温度范围；研究了沙柳树皮量对于刨花板MOR、MOE、吸水厚度膨胀率、握钉力以及内结合强度的影响，结果证明沙柳树皮量对于刨花板的各项性能指标影响显著，它的掺入降低了刨花板的各项性能；对沙柳树皮板的研究表明，沙柳树皮板的各项性能与同类树皮板的性能基本相近，建立的二次回归模型稳定，并利用回归方程求出了适宜的沙柳树皮板制造工艺。

With CO2 as acidifying agent, potassium chromate was directly reduced to chromic oxide hydrate under hydrothermal conditions using formaldehyde as reducing agent.

以CO2气体为酸化剂，小分子有机化合物甲醛为还原剂，通过表面活性剂处理，在水热条件下直接还原铬酸钾水溶液得到水合Cr2O3，继而800℃下煅烧得到球形Cr2O3超细粉体。

But, he added, a little bit of acid, like a high acid wine or lemon juice, will do wonders in smoothing out intractable curds.

不过，他补充说，一点点酸，比如高酸葡萄酒或柠檬汁，对于融化这些难处理的奶酪块有奇效。

Therefore it is to guarantee the safe operation of the boiler to choose chemistry to wash the method correctly in the course of constructing, it is that guarantee boiler wash safe and reliable by chemistry, it raises result of washing lengt...

因此 ，在施工过程中正确选择化学清洗方法是确保锅炉安全运行、保证锅炉化学清洗安全可靠、提高清洗效果、延长锅炉使用寿命的重要因素。主要探讨锅炉酸洗过程中的腐蚀机理，缓蚀剂的使用和酸洗后防腐处理

And they end up predominantly in the fine particle fraction in the fly ash duringcombustion.When biomass sample is pretreated by using chemical fractionation method,the content of volatile alkali in fuels decreases clearly and large amount of available C1 andS is also leached.So,during combustion the vaporization amount of alkali reduces and theformation of fine particle fraction in the fly ash is limited.

而当样品在经水洗分离和酸洗分离的化学处理后，燃料中易气化部分的碱金属元素含量大幅减少，大量水溶态或酸溶态的S，Cl等非金属&催化性&元素同时也被分离脱除，从而导致燃料样品燃烧时的碱金属气化量下降，且在成灰过程中向细微颗粒转化的途径也受到较大的抑制。
