Abundant of estrogens is excreted via human urine, bringing the risk of micro-pollution during nutrients recovery from urine. This study investigated the characteristics of estrogens during the ammonification of urine, and then experiments were conducted to study the adsorption of estrogens on struvite, a potential product to recover nutrients from urine. The results showed that no 17a ethinylestradiol...
The adsorption performance of aminoalky cellulose (AmAC) for 2,4,6-trinitrotoluene (TNT) was investigated in a fixed bed column. The fixed bed column parameters such as bed height, flow rate, influent TNT concentration were studied by a series of dynamic adsorption experiments. The result showed AmAC was an effective adsorbent for removal of TNT, and the equilibrium uptake increased from 27.76 to...
Washing coal usually brings about 0.2m3/t wastewater (in terms of closed circulation) due to transpiration, which provides an effective space for the recycle of coke-plant wastewater. The effluent from phenol-cyanogen wastewater biochemical disposal station is used as complementary water for washing coal, and Closed-Cycling System in coal preparation plant is introduced to make industrial experiment...
