The paper investigated the treatment effect of modified rice husk as an adsorbent on wastewater containing Zn(II). Langmuir and Freundlich equations quantified the Zn(II) removal effect of modified rice husk. We analyzed characteristics of adsorption kinetics, the initial pH value, temperature effect on adsorption process, and compared with the regeneration efficiency of adsorbent. The results showed...
In accordance with emission characteristics and treatment situation of rural domestic sewage, this experiment studied the effect of domestic sewage treatment in rural areas through the design of a stabilization pond miniature-testing device. In the stable test operation phase, the average removal rates of COD, TP, and NH3-N were respectively 92.53%, 97.57%, and 95.10% in an aerobic pond reactor. The...
Magnesium-ammonium-phosphate precipitation method (MAP) is a newly-developed technique to remove ammonia nitrogen from wastewater. In this study, MAP method has been studied by using MgCl2-6H2O and Na2HPO4-12H2O as precipitators for treating highly concentrated ammonia nitrogen wastewater. The effect of pH value, formulas of precipitation and precipitator ratio on MAP precipitation efficiency has...
