生態(tài)彈性填料及陶粒在微污染水體處理中的應(yīng)用研究
摘要: 生態(tài)彈性填料是一種模擬天然水草形態(tài)加工而成的新型水處理材料,近年來在污水處理中得到了廣泛應(yīng)用.其具有比表面積大、去除有機(jī)物容積負(fù)荷高、生物附著性好、空隙可變、不易堵塞、適應(yīng)性強(qiáng)、操作管理簡便等優(yōu)點(diǎn);陶粒具有較高的孔隙率及適中的密度,所有這些都有利于微生物的生長.本文采用人工濕地作為構(gòu)筑物對崇明前衛(wèi)生態(tài)村中心湖的水體進(jìn)行處理,結(jié)果表明,經(jīng)此工藝處理后的水體,CODCr、TP、TN、氨氮等指標(biāo)達(dá)到或優(yōu)于國家三類水質(zhì)標(biāo)準(zhǔn).并為工程實(shí)施提供了科學(xué)依據(jù). Abstract: The ecological fibre is a new water treatment material that is processed by simulating the shape of wild water plant. In recent years it has been applied broadly in sewerage treatment for its following advantages: big specific surface area; high capacity in removing organic matter; good microbiological adhesiveness; variable pore sizes; wonderful performance in preventing jamming; flexibility in operation and management, etc. Ceramic padding has high porosity and moderate density; all of these are favorable to the growth of microorganisms. This paper discussed treating the micro-polluted water by using arts and crafts of constructed wetland, the results show that some indexes of the treated water reached or exceeded band 3 national water quality standard, these indexes include CODCr, TP, TN and NH+4-N and so on. The results can provide reference for project design. 作 者: 張小東 楊波 陳季華 奚旦立 ZHANG Xiao-dong YANG Bo CHEN Ji-hua XI Dan-li 作者單位: 東華大學(xué),環(huán)境科學(xué)與工程學(xué)院,上海,200051 期 刊: 中山大學(xué)學(xué)報(bào)(自然科學(xué)版) ISTICPKU Journal: ACTA SCIENTIARUM NATURALIUM UNIVERSITATIS SUNYATSENI 年,卷(期): 2007, 46(z1) 分類號: X703 關(guān)鍵詞: 生態(tài)彈性填料 陶粒 微污染水體 天然水草 Keywords: ecological fibre ceramic padding micro-polluted water wild water plant【生態(tài)彈性填料及陶粒在微污染水體處理中的應(yīng)用研究】相關(guān)文章:
