In order to save the energy of the wastewater treatment, the SBR process was investigated under low DO condition with real-time control. The pH, DO and ORP probes were monitored online with the reaction temperature was 23±0.5¿, MLSS was 2500 mg/L and the aeration volume was 20 L/h. The results showed that PO43--P and the ammonia concentration in the(More)

In order to improve ammonia removal capability from wastewater, zeolite was modified in this paper. Some results for virgin zeolite were revealed by SEM, and its structure showed some ions such NH4+ enter into the pore way in the zeolite. The best results could be attained by combined modification with orthogonal experiment. The adsorption capacity of(More)
In order to tackle the problem for remove ammonia from polluted water, clinoptilolite is used for adsorbing the ammonia from wastewater, and biochemical regeneration for ammonia removal was investigated. The results showed that the data were fit to Langmuir isotherms for ammonium ion uptake onto clinoptilolite. For biochemical regeneration experiment, it(More)

There is a globally increasing issue that groundwater contamination by nitrogenous fertilizer in the contemporary world, however as an important water, groundwater always serves, especially in rural region. To address this problem, biological nitrification and denitrification course has been pervalently used for removal of nitrogenous pollutants from(More)
Based on the practical engineering and aimed at the food wastewater, a series experiments were conducted to investigate parameter on the effluents qualities by submerged membrane bioreactor (SMBR). A better removal performance in a SMBR could be achieved to treat food wastewater. The removal efficiencies in MBR were obtained worked with HRT at 10h, DO at(More)
In order to save operating costs of sewage treatment plant, the SBR process was investigated with low DO condition by means of real-time control. when the reaction temperature was 21±0.5, aeration rate was 30 L/h, the pH, DO and ORP probe were monitored online and the real-time control strategy has been set up. The results showed that the variation of(More)

Cyclops of zooplankton propagated excessively in eutrophic water body and it couldn’t be effectively inactivated by the conventional disinfection process. In order to tackle this problem, a study of removal effect on Cyclops with oxidants in a drinking plant in China was conducted. Among five oxidants, chlorine dioxide was more effective against(More)
Biological denitrification is a simple and cost effective method to treat groundwater contaminated by nitrate. However, this process is non-linear, complex and multivariable. In order to tackle the problem to remove nitrate from polluted groundwater, based on artificial neural network (ANN) technique and GUI(Graphical User Interfaces) function of MATLAB, a(More)
