The Dynamics of Macroinvertebrate Assemblages in Response to Environmental Change in Four Basins of the Etueffont Landfill Leach
      


As one of the most popular ways for the disposal of municipal solid wastes, the fully-containing sanitary landfill meets with many problems and difficulties in its practical application. This paper presents the design concept of semicontaining sanitary landfill and elucidates the rationality and necessity of its development. The mechanisms by which landfill leach is attenuated by the surrounding soil and waters are analysed. The total volume control techniques for leaching and other problems needed for...

As one of the most popular ways for the disposal of municipal solid wastes, the fully-containing sanitary landfill meets with many problems and difficulties in its practical application. This paper presents the design concept of semicontaining sanitary landfill and elucidates the rationality and necessity of its development. The mechanisms by which landfill leach is attenuated by the surrounding soil and waters are analysed. The total volume control techniques for leaching and other problems needed for further study are discussed.

全封闭卫生填埋是目前流行的城市固体废弃物最终处置方法之一。但是由于技术和经济方面的原因,该方法在实际应用中存在不少问题。笔者提出底部开放的半封闭卫生填埋设计思想,阐述了发展这种填埋方式的合理性和必要性,分析了填埋场渗滤液经由土壤和周围水体的衰减机制,对渗滤液总量控制技术和尚待研究的其它问题进行了讨论。

The treatment of landfill leach which had been acclimated(CODCr=450 mg/L)by using UV/H2O2/ferric oxalate was studied.The result indicates that the optimum conditions for the reaction are pH of around 4.0 and total dosage of 14 mL/L.The added quantity of ferric oxalate must be properly.Insufficient ferric oxalate has disadvantageous efficiency and the useable photon cannot be completely transformed into chemical energy.On the other hand,excessive ferric oxalate can cause brown turbidity to be given in the solution.The absorption efficiency of UV turns lower because a great deal of photon has been reflected and lost.Excessive hydrogen peroxide can make its decomposing rate decrease and the stability of complex ferric ion increases.But insufficient hydrogen peroxide has also strong disadvantageous effects on the reaction rate.The removal percentages of CODCr and chromaticity for the infiltration wastewater are respectively around 80% and over 90% after the reaction has been run for 30 min in which the total dosage is 14 mL/L(including 30% H2O2 6 mL/L and 0.1 mol/L ferric oxalate 8 mL/L).

利用UV(125W) H2O2 草酸铁处理已经过生化处理的垃圾渗滤液(CODCr为450mg L)时,反应较佳条件是pH值为4 0及总药剂用量为14mL L。草酸铁的用量要适当,投加量过少,混凝效果较差,有效光子不能完全转化为化学能,处理效果不理想;投加量过多,溶液形成棕色混浊,使紫外光的吸收降低,造成光散射,降低反应速度。而H2O2的投加量过多,将使铁的络合物更加稳定,H2O2的分解速率受到限制,投加量过少,效果也会降低。当总药剂用量为14mL L(其中30%过氧化氢6mL L,0 1mol L草酸铁溶液8mL L)时,反应30min后,CODCr去除率可达80%左右,脱色率可达90%以上。

Fecl_3·6H_2O was used as coagulant without adding photocatalyst to treat landfill leach in the experiment. The experimental result shows the optimum addition dose is 500mgL~(-1) ,the optimum pH3 ;under the condition of pH3 ,addition dose 500mgL~(-1), and COD amount added 4800 mgL~(-1), The total removal efficiency of COD can attain 69.7% after 4 hour irradiation of the high-pressure mercury lamp.

本文研究了采用FeCl3·6H2O作混凝剂后不另加光催化剂来完成光氧化反应.实验结果表明:FeCl3·6H2O的最佳投加量为500mgL-1,在FeCl3·6H2O投加量为500mgL-1和垃圾渗滤液初始浓度为4800mgL-1条件下,pH值在3左右处理效果最好;采用UV Fe(Ⅲ)工艺,垃圾渗滤液在pH=3条件下用高压汞灯光照4h后COD的去除率可达到69 8%.
