About Myself
My name is Qin Zheng. I am from Xiangshan, which is a small town in Ningbo District. It is very beautiful and nowadays a lot of films and TV programmes are shot there. More and more people went there for a holiday. The people there are laborious, virtuous and warm hearted. I’m much felicitated that I was born and raised up there. It is my hometown and I will love it forever.

My family has been engaged in farming for generations. My relatives are all farmers. My ancestors and my parents have plotted all their life on thin ground. In my family, my father, my mother and I, that’s all.

Now I’m in grade three, a third year student in Jiaxing University. Since I have made a lot of friends, I find life in this university both happy and rewarding. I live happily here. I like climbing mountains. I like singing, listening classical music. I like essay, also novel, but my favorite is essay. Unfortunately, although I have read so much, my writing is still not very good.

I hope that I can be an useful person for our society. But at the moment, my knowledge is still not rich enough. In order to realize my objectives in life, I will study hard and gain more and more skills and knowledge, such as speaking English and using computer. If I have enough money after graduation from school, I will study driving. It is good to have a good job when someone can drive a car or a bus.

再生纸废水物化处理方法研究
摘要：通过对三种无机混凝剂（聚合氧化铝、聚合氯化铝、聚合硫酸铁）和一种有机混凝剂（聚丙烯酰胺）在不同影响因素（投加量、pH 值、搅拌速度、搅拌时间）下，对再生纸废水物化处理效果的研究，选出各种混凝剂的最佳投加量、pH 值、搅拌速度和搅拌时间，结果聚合氧化铝在处理再生纸废水方面效果最好。结果表明1%聚合氧化铝在pH 值为6～7范围内，投加量为8mL，以150r/min 的搅拌速度搅拌6 分钟，再生纸废水的浊度去除率可以达到90%以上，COD 的去除率可以达到80%上。
关键词：再生纸废水；聚合氧化铝；聚合氯化铝；聚合硫酸铁；聚丙烯酰胺

The Physical-chemistry Processing Method Research of Waste Water in the Process of
Producing Regenerated Paper
Abstract: By way of research three kinds of inorganic coagulants ( polymerization alumina,polymerization aluminum chloride and polymerization iron sulfate ) and one kind of organiccoagulant ( polyprogylene polyam ide ) under the different influence factors ( throwing thecapacity adding, pH's value, stirs speed, stirs time ), to waste water in the process of producing regenerated paper the physical chemistry processing effect, selects out that various coagulants optimum throwing the capacity adding, pH's value, stirs speed and stirs time, concludes to polymerization alumina at the aspect that deals with waste water in the process of producing regenerated paper effect is the best. Indicates: 1%polymerization alumina in pH's value is for 6 – 7 scopes at last, throws the capacity adding for 8mL, with 150r / min the stirring speed stirred 6 minutes, the haziness of waste water in the process of producing regenerated paper goes that removing rate can achieve more than 90%, and COD goes that removing rate can achieve more than 80%.
Key words: waste water in the process of producing regenerated paper;polymerization alumina;polymerization aluminum chloride; polymerization iron sulfate; polyprogylene polyam ide
