【摘要】：循環(huán)水養(yǎng)殖在水產(chǎn)養(yǎng)殖中占有重要地位,水質(zhì)凈化是其核心技術(shù)。該文模擬循環(huán)水養(yǎng)殖系統(tǒng),對3種濾布填料(碳纖維、滌綸無紡布、工業(yè)濾紙)構(gòu)成的掛簾式生物濾池進(jìn)行研究,通過比較3者的氨氮處理效果來篩選最佳濾布填料,并探究最適濾布填料在不同工況條件(流速、溫度、初始氨氮濃度)下的最優(yōu)處理效果。結(jié)果表明,碳纖維生物濾池掛膜速度快,生物量多且穩(wěn)定,對氨氮和亞硝態(tài)氮有更好的去除效果;在30℃條件下,初始氨氮為10 mg/L,經(jīng)過6 h反應(yīng),氨氮去除率可達(dá)97%;在一定范圍內(nèi)增大流速,會提高其氨氮的去除效率;初始氨氮濃度為15 mg/L時,氨氮平均去除速率達(dá)到0.5 mg/(L·h)。以上研究結(jié)果為掛簾式生物濾池在循環(huán)水養(yǎng)殖水質(zhì)凈化中的應(yīng)用奠定了實(shí)驗(yàn)基礎(chǔ)。
[Abstract]:Circulating water culture plays an important role in aquaculture, water purification is its core technology. In this paper, three kinds of filter cloth fillers (carbon fiber, polyester non-woven fabric, industrial filter paper) were studied by simulating the circulating water culture system. The best filter cloth fillers were selected by comparing the ammonia nitrogen treatment effect of three filter cloth fillers. The optimal treatment effect of filter cloth packing under different operating conditions (flow rate, temperature, initial ammonia nitrogen concentration) was investigated. The results show that carbon fiber biofilter has the advantages of fast membrane forming rate, high biomass and stable biomass, better removal of ammonia nitrogen and nitrite nitrogen, and at 30 鈩，
