Through analyzing and comparing the treatment of fracturing fluid flowback at home and abroad, it can be found that fluid derived organic waste water can be handled by micro electrolysis economically and efficiently. But there are also some shortages of traditional micro electrolysis. So this paper discusses a new micro-electrolysis technology, namely cavitation-impinging stream electrolysis technology which has several advantages in high concentration organic wastewater treatment. The technology can not only solve the problems that the passivation of process and the plugged equipment in the treatment of fracturing fluid flowback fluid by traditional micro electrolysis, but also can better promote the reaction from the reaction kinetics with the help of Coupling application about cavitation and impinging stream technology, so as to realize the purpose of improving the reaction rate and efficiency.

Abstract. UASB, bio-contact oxidation, coagulation and floating process was adopted in treatment of juice wastewater. Operation results show that when the main pollutants of COD, BOD and SS in the influent were 6033 mg•L-1, 2512 mg•L-1 and 2200mg•L-1, the effluent could reach 63 mg•L-1, 25 mg•L-1 and 29 mg•L-1, respectively, with the removal rate of 99.0 %, 99.0 %, 98.7 %. The effluent reached the I-class criteria specified in Integrated Wastewater Discharge Standard (GB8978-1996) (COD < 60 mg•L-1, BOD < 20 mg•L-1, SS < 20 mg•L-1). The process provides a practical reference for the similar high concentration organic wastewater treatment processing.

AbstractThe occurrence of developmental stages of endoparasite germs (cysts, oocysts, protozoa, and helminth eggs) as an indirect detection factor of endoparasitoses circulation in the environment, was examined in raw municipal wastewater, sludge and biologically cleaned waste water. Examination of municipal wastewater and sludge from five monitored wastewater treatment plants (WWTPs) in east Slovakia, from various fractions of municipal wastewater, confirmed 35.87 % positivity of samples for the endoparasitic germs. Among of all analysed samples 11.09 % were protozoan oo(cysts) and 20.87 % were helminth eggs. 3.91 % of samples showed positivity to both the helminth eggs and protozoan oo(cysts). In the raw wastewater the protozoa comprised of Giardia spp. (1.08 %) and Entamoeba spp. (1.08 %). The helminth eggs primarily consisted of Ascaris spp. (4.35 %) and strongyle-type eggs (3.26 %). No germs of protozoa or helminths were found in the treated wastewater. However, the highest presence of the germs was found in drained stabilised sludge. The average number of oo(cysts)/kg was 2.86±0.24 and the average number of helminth eggs/kg was 5.77±0.09. In all kinds of sludge, obtained during the process of wastewater treatment, there were protozoan (Giardia spp., Cryptosporidium spp., Entamoeba spp.) and helminths eggs (Ascaris spp., Trichuris spp., Taenia spp., Hymenolepis spp., or strongyle-type eggs) presented. In drained (condensed) stabilised sludge the eggs of Capillaria spp. and Toxocara spp. were also detected. From the epidemiological aspect the sewage sludge, due to high concentration of protozoal oo(cysts) or helminth eggs, represents a significant epidemiological risk for the endoparasitoses dissemination.

Wastewater from scheelite flotation tailings slathered a lot of sodium silicate in the flotation process, a large number of silicate minerals residues remain in the wastewater, forming suspension bodies difficult to be naturally subsided. With high concentration of suspended substance and pH of 11 or more, this kind of wastewater belongs to unmanageable mine wastewater. Research shows that, pretreating the waste water with Sulfuric acid and calcium chloride, adjusting pH to 7-8 and adding polyacrylamide on flocculating-sedimentation combined can remove suspended solids effectively, offering theoretical basis for wastewater recycling and disposing mine wastewater, which is of great importance.

Pharmaceutical and textile industries widely use inorganic and organic components which undergo different chemical and biochemical reactions with the ground water systems. The removal of organic wastes from effluents was carried out using a composite adsorbent. Four different samples were collected from the Gonoshasthaya Antibiotic Limted, Gonoshasthaya Pharmaceuticals Limited, Pakiza Dyeing and Printing Industries Limited and Bangladesh Dyeing and Finishing Industries Limited. Synthetic effluents of four types were prepared maintaining a similar chemical average of the collected samples. All the samples contained a high concentration of TDS, TSS, TS, COD and BOD5. The composite adsorbent performed excellently for all the samples. The concentrations of the components contained in the waste water were analyzed by UV-Visible spectrophotometer and High Performance Liquid Chromatography (HPLC). After the treatment, the decreasing trend of the absorbance and total peak area indicated that the significant amount of effluent materials were removed. Bangladesh J. Sci. Ind.

Analysis of literature sources suggests that the use of anaerobic treatment methods is especially effective for high concentrations of contaminants in wastewater, as well as for large volumes of water supplied for treatment, which is typical for industrial wastewater. In biotechnological production and food industry, waste water has a high level of pollution with organic compounds, it is advisable to use anaerobic treatment methods. Anaerobic wastewater treatment processes are characterized by low energy consumption and the ability to recover energy through the combustion of methane. To ensure the required temperature regime for the operation of the bioreactor, a new design of the heat exchange device of the anaerobic bioreactor with immobilized microorganisms has been developed. This design of the bioreactor can provide the required degree of wastewater purification at significantly lower costs for construction, operation, and material and energy resources. For clarity, the design features were designed bioreactor with a plane load of bundled software SOLIDWORKS and a mathematical model of the processes of anaerobic wastewater treatment.
