This study investigated the effects of unsaturated zone depth, temperature, and alkalinity on biological nitrogen removal in biofilters enhancing nitritation-anammox process. The results showed that the highest total inorganic nitrogen removal rate of 20.2 g/m3·d was achieved when the depth ratio of ...

2.On the basis of careful studing over Xindian area s hydrogeochemistry information we see that rock characteristic, depth, and physical chemistry properties in the zone of aeration controll the three nitrogen s adsorption and transformation.对辛店地区的实际资料研究表明,包气带岩性、厚度、理化性质对三...
(2019) developed a new iterative scheme with the vertical net recharge and unsaturated zone depth used as the exchange information, which represents a trade-off between the model accuracy and computational costs. Sign in to download hi-res image Fig. 2. A spatial diagram of the coupled model ...
The vulnerability of the aquifer systems to pollutants is dependent on a number of factors, including soil type, characteristics and thickness of materials in the unsaturated zone, depth to groundwater and recharge to the aquifer 含水层系统受污染的难易程度取决于若干因素,包括土壤种类、非饱水带...
For the airflow induced by water table fluctuations and infiltration, the propagation depth of the flow is the whole thickness of the unsaturated zone. This is due to the fact that the flow occurs between the water table and the ground surface. Furthermore, Table 3 shows that all kinds of...
Unsaturated zone thickness averaged 4.7 m but reached a maximum of 18.7 m. Average annual recharge to ground decreased from 15.9 to 11.1 cm as the unsaturated zone increased in thickness from 1 to 10 m. These point estimates of recharge are at the lower end of previously published values, ...
were taken to determine the NOconcentration in the solution of the unsaturated zone and to estimate the soil N balance. Transit time for water to move to the 15-m depth was calculated from drainage volumes and volumetric water contents. Nitrogen balance was calculated from data for N input, ...
