    High concentration of fosfomycin pharmaceutical wastewater was treated by wet air oxidation (WAO). The kinetic characteristics of the removal of total organic phosphorus (TOP) and chemical oxygen demand (CODCr) in WAO of fosfomycin pharmaceutical wastewater were investigated. The effects of reaction temperature and oxygen partial pressure on TOP and CODCr removal were quantified. The results showed that the removal of CODCr and TOP in WAO was divided into fast and slow reaction steps and the removal process was well accorded with piecewise first-order kinetic model. Generally, the removal rates of TOP and CODCr increased with increasing reaction temperature and oxygen partial pressure in both fast and slow reaction steps, and the removal rates of the slow reaction step were found to be less sensitive to reaction temperature and oxygen partial pressure. According to Arrhenius equation, the activated energies for TOP oxidation were Eafast 68.6 and Easlow 44.7 kJ/mol, and for CODCr removal were Eafast 41.0 and Easlow 24.5 kJ/mol at 1.0 MPa oxygen partial pressure.

    The berberine pharmaceutical wastewater containing copper was treated by the bipolar-electrochemical process. The effects of electrode distance, current intensity and initial pH on the removal efficiencies of berberine and Cu2+ were studied in details. The optimal condition was determined as followed: the electrode distances of 2.0 cm, the current intensity of 4.0 A and initial pH of 0.4. Under the conditions, the concentrations of berberine and Cu2+ reduced from 1 700 and 22 000 mg/L to 120 and 55.0 mg/L within 300 min, and the removal efficiencies reached about 93.3% and 99.9%, respectively. According to the weight method, copper recovery rate was calculated as 97.1%. That is, about 21.35 kg of Cu could be recovered from per ton of such wastewater. Thus, it was proved that the bipolar-electrochemical process was an effective method for the treatment of berberine wastewater containing copper.

    The hybrid membrane bioreactor(HMBR)was designed by using the new biofringe (BF) filling combined with A/O system. The BF biofilm was with dynamic natural cultivation and continuous water seepage, and the pilot-scale starting-up tests were carried out for treatment of acrylic fiber wastewater. The results showed that the system biofilm could be hung effectively and rapidly, with short starting-up time and stable system operation. The BF filling took good effects on adsorbing the activated sludge in the reactor. After the biofilm was hung stably with the HRT controlled at 36 h, the nitration liquid return rate at 100% and the influent flow at 600 L/h, the water quality after treatment proved to be stable and the effluent ammonia-nitrogen concentration was under 5 mg/L, better than Grade 1 of the National Standard of Acrylic Fiber Industry (15 mg/L), and the average removal rate of the total nitrogen could reach 55.86%, which demonstrated that the system had good denitrification ability. The membrane interception had certain effect on the chemical oxygen demand (CODCr) removal but no effect on ammonia-nitrogen removal. Also, the simultaneous nitrification-denitrification (SND) occurred in the reactor.

    The water environmental problems caused by industrial pollution were serious in Liao River Basin. The pollution problems in different areas of the watershed were related with industries in the areas and the type and concentration of pollutants had obvious industry characteristic. There are a great variety of water treatment technologies; however, different water treatment technologies have obviously different treatment effects for wastewater with different characteristics. Considering that the application scope of water treatment technologies was different and the wastewater had obvious industrial characteristics, multiple-index comprehensive assessment research was performed to find out the optimal technologies for different industries by considering pollutant reduction effect, treatment efficiency and economic factors in order to realize rational allocation of technologies, using the methods such as fuzzy and grey integrated evaluation method and analytic hierarchy process(AHP) method. Because the assessment processes involved both complex mathematic models and big calculation task, the assessment efficiency was not high, and the accuracy was very difficult to guarantee. An assessment software for water pollution treatment technologies was thus developed. The design principles, structure, functions as well as application cases of the software were introduced. The results showed that the application of this software could significantly improve the assessment efficiency and accuracy for water pollution treatment technologies.

    XIAO Shu-hu SONG Yong-hui XIAO Hong-kang ZHANG Guo-fang
    2011, 1 (4):  353-358.  doi: 10.3969/j.issn.1674-991X.2011.04.060
    Abstract ( 3935 )   PDF (805KB) ( 1562 )   Save
    Photoelectrochemical treatment of landfill leachate with activated carbon fiber (ACF) cathode and RuO2/Ti anode was carried out. Firstly, the treatment efficiencies were compared among electro-oxidation, electro-oxidation/electro-Fenton and  photoelectrochemical processes. Then the effects of initial pH and current intensity were studied in details. Simultaneously, the variations of organic speciation and biodegradability were investigated. The results showed that the degradation efficiency and rate were by far higher than the sum of electro-oxidation and electro-oxidation/electro-Fenton, thus the hybrid photoelectrochemical process presented a good synergetic effect. The formations of hydroxyl and chlorine radicals, which were disassociated from H2O2 and active chlorine by UV and Fe2+, were proposed to be the main mechanism. Current density was the control factor and the degradation rate of TOC increased gradually with current density. Under the conditions of initial pH value of 2.0~5.1, current intensity of 15.0 mA/cm2, and Fe2+ addition of 1 mmol/L, the removals of TOC reached about 80% within 300 min and the first-order kinetic constants ranged between 6.1×10-3 ~ 6.6×10-3 min-1. UV-Vis and gel permeation chromatography (GPC) spectra showed that the biorefractory humic and fulvic substances could be transformed into small molecules or even be mineralized, which resulted in the increase of biodegradability and the BOD5/COD reached about 0.42.
