辉县市城区环境空气质量现状及污染防治对策

对辉县市城区2006—2011年间环境空气质量监测数据进行了评价，并对城区污染物浓度时空变化进行了分析。结果表明，辉县市城区大气污染主要表现为可吸入颗粒物污染严重，主要是能源结构不合理、锅炉废气污染严重、城区道路保洁方式落后等原因造成的，由此提出了合理规划城市布局、减少结构性污染等对策。

The Present Situation of Environmental Air Quality and Preventing Measures in Huixian City

The anti-scale of α-aminoadipic acid-N, N＇-dimethylidene-phosphonic acid （AADMP） were assessed by the bubbling method. The effect of scale inhibitor concentration, pH, Ca2＋] , and temperature on AADMP performance were discussed. And the anticorrosion property of AADMP was assessed by a rotary hanged weight losing method. The test results indicated： AADMP is fit for conditions as follows： high rigidity, pH weakly alkaline value, medium low water tempera- ture. Recommended scale inhibitor concentration for 25 mg/L, the scale inhibition rate reached 80%.30 mg/L of AADMP showed well effect of anticorrosion rate for A3 carbon steel and copper anticorrosion rate reach above 80%. Under the running condition of 5 mg/L of AADMP and 4 mg/L of Zn2＋, the antieorossion rate of A3 carbon steel and copper were about 90%. So the AADMP is an excellent performance of scale and corrosion inhibitor.
