  • Treatment effect of domestic sewage by constructed wetland

    Treatment effect of domestic sewage by horizontal subsurface flow constructed wetland with different plants, such as Phragmites communis and Typha latifolia, was studied. The results showed that: (1) the removal rates of CODcr, total phosphorus (TP), total nitrogen (TN) were related to seasons, which were summer>;autumn >; spring. (2) The removal rates of CODcr, TP, TN in Phragmites communis & Typha latifolia wetland were lower than those from Phragmites communis wetland or Typha latifolia wetland, when they were planted in the same density. This illustrated that there should be some antagonistic actions between Phragmites communis and Typha latifolia. (3) The removal rates of pollutants were different, when wetlands were planted in different density of Phragmites communis. For example, the TP removal effect in summer was: NO.1 (92.1%) >;NO,2 (91.1%) >;NO,3 (79.3%), while the Phragmites communis density was: NO.1 (125 plants /m2) >;NO.2 (94 plants /m2) >;NO,3 (63 plants /m2) .This illustrated that 125 plants /m2 was a reasonable density. (4) The removal rates of CODcr, TN and TP in NO.l wetland were, 57.6-81.8%, 45.3-79.6% and 71.1-92.1% respectively.

  • Characteristics of rural wastewater treatment by no reflux swimming bed biofilm reactor

    A novel swimming bed reactor with no reflux which suit for small scale wastewater treatment was developed. The performance of the reactor for treating domestic wastewater was investigated. Steady removal effect with 71.75% of average COD removal rate was achieved in hydraulic retention times (HRT) of 20.74 h ~ 4.30 h. When hydraulic retention time (HRT) was at 8.12h with average NH<sub>4</sub><sup>+</sup>-N volumetric loading of 0.25 kg/(m3.d), 78.5% of average NH<sub>4</sub><sup>+</sup>-N removal rate was obtained. In the optimal condition with pH of 6.7~7.7, 92.2% of average NH<sub>4</sub><sup>+</sup>-N removal rate was obtained. Presence of protozoa and metazoa on the biofilm were observed and steady food chains was contributed to the sludge reduction, 0.2840 of sludge yields (MLSS/CODremoved) was obtained in the experiment.

  • Effect of PH on the production of N<inf>2</inf>O during denitrification process

    To investigate the effect of pH on the production of N2O during shortcut denitrification process, NaNO2 was added into the system to ensure that the initial concentration of NO2--N was 40mg/L. HCl and NaOH were used to regulate pH of the system using sequencing batch reactor with volume of 2.4L. Results showed that nitrite reduction rate under different pH varied little in the shortcut denitrification system. The maximum nitrite reduction rate was 0.084mgN/(mgMLSS-h) and the minimum nitrite reduction rate was 0.071mgN/(mgMLSSh); the production of N2O could reach 4.272mgN/L, which accounted for 10.68% of influent nitrite concentration during nitrite denitrification when pH was 6.5. The production of N2O reached only 0.573mgN/L when pH was 8.0. The reasons of high production of N2O under low pH during denitification process were mainly: (1) low pH had strong inhibition on N2O reductas; (2) low pH played a role of screening strains.

  • Two-stage treatment of edible oil-containing wastewater: Yeast coupled with activated sludge unit

    Two Sequencing Batch Reactors (SBRs) were coupled to treat edible-oil containing wastewater directly. Ten yeast strains were inoculated to the first SBR to treat high-strength oil-containing wastewater. The effluents of the system were further degraded by activated sludge in the second SBR. The results show that each yeast can efficiently decompose edible oil-containing wastewater with the COD removal rate above 80%; The mixture of ten yeast stain can cultivated in an open system without any molds and bacteria inhibitor addition to produce yeast biomass which processes a good settle ability. In 100 day continuous wastewater treatment by the first stage, COD and Oil removal rate achieve 88.9-97.5% and 93.4-99.9% respectively under the influent conditions of the COD of 9500-24000 mg/L and Oil of 3300-14000 mg/L. The effluent with COD varied from 300 to 700mg/L was treated by the second stage and the final effluent of COD was below 100 mg/L which meets the standards for wastewater discharge.

  • Effects of salinity on purification efficiency of constructed wetland with mangrove plant Rhizophora stylosa for eutrophic wastewater treatment

    There is obvious effect for eutrophic wastewater treatment by constructing mangrove wetland, but mangrove plants grow under circumstances of a certain salinity, so this may influence the wastewater purification efficiency. Rhizophora stylosa, one of dominant mangrove species in South China, was used to construct simulated wetlands for eutrophic wastewater treatment. After 9 months irrigation to 8 groups of wetlands with wastewater at salinities of 0<sup>0</sup>/<sub>00</sub>, 5<sup>0</sup>/<sub>00</sub>, 10<sup>0</sup>/<sub>00</sub>, 15<sup>0</sup>/<sub>00</sub>, 20<sup>0</sup>/<sub>00</sub>, 30<sup>0</sup>/<sub>00</sub>, 40<sup>0</sup>/<sub>00</sub> and 50<sup>0</sup>/<sub>00</sub>, respectively, the growth, photosynthesis, amounts of nitrogen (N) and phosphorus (P) assimilated by plant, and the treatment efficiency were surveyed. The optimum salinity for Rhizophora stylosa growth was 15~20<sup>0</sup>/<sub>00</sub>. The net photosynthesis rate, stomata conductance and transpiration rate of leaves increased with the elevation of salinity, reached the highest between 10<sup>0</sup>/<sub>00</sub> and 20<sup>0</sup>/<sub>00</sub>, and then decreased. At salinities of 15<sup>0</sup>/<sub>00</sub> and 20<sup>0</sup>/<sub>00</sub>, the content of N in leaves and stems was the highest, but in roots it decreased with the salinity increase. The content change of P in leaves and roots was similar with N, while at low salinity the content of P in stems was higher than that at high salinity. The removal rate of N in wastewater was above 80% for all treatments of different salinities, but at salinities of 10~30<sup>0</sup>/<sub>00</sub> there was the highest treatment efficiency with removal rate of 84.1~85.2%; the removal rate of P in wastewater was 98.11~98.82% for all treatments, and at salinities of 10<sup>0</sup>/<sub>00</sub> and 20<sup>0</sup>/<sub>00</sub> it was a little higher than at other treatments. The amounts of N and P removed by plant assimilation accounted for 5.9~11.2% of total N and 1.3~3.3% of total P removed from wastewater, respectively, and most of them transferred into sediment. At the optimum salinity for the plant growth, there was the highest purification efficiency for eutrophic wastewater treatment by constructed wetland with Rhizophora stylosa.

  • Productive experiment on tannery wastewater treatment

    Leather industry was a dominant industry in China, but the considerable tannery wastewater resulted in several serious environmental problems, which brought huge harm to human health. In this paper, coagulation-sedimentation combined with biological contact oxidation and SBR was explored for tannery wastewater treatment. Under the hydraulic retention time of 15h of biological contact oxidation process, both the COD and NH<sub>4</sub><sup>+</sup>-N removal efficiency was more than 85%, and the shock of raw water concentration has little influence on this process. In the subsequent SBR process, the removal rate of 65% and 85% of COD and NH<sub>4</sub><sup>+</sup>-N could be achieved respectively under the DO of 2mg/L and aeration time of 6h. The overall effluent of COD was 90mg/L and NH<sub>4</sub><sup>+</sup>-N was 4mg/L approximately, which showed evident superior to the traditional physico- chemical and biochemical processes. The combined process was suitable for tannery wastewater treatment and showed favorable resistance to shock loading.
