水电站配套鱼类增殖站养殖废水水质估算模型

Estimation Model of Aquaculture Wastewater Quality for Fish Breeding Station in Hydropower Station

通过对鱼类增殖站的物料平衡和水平衡研究,建立其养殖废水水质估算模型,探讨鱼类增殖站养殖废水的分析方法。废水中总氮(TN)、总磷(TP)、悬浮物(SS)与饵料重量(W)和进水量(Q)的估算公式为CTN=0.01024W·Q-1、CTP=0.00045W·Q-1、CSS=0.277W·Q-1。估算泸定鱼类增殖站养殖废水中,CTN=0.395 mg/L、CTP=0.017 mg/L、CSS=10.68 mg/L;与实测水质进行验证结果表明,Sig.(双侧)>0.05,表明实测值与估算值之间没有显著差异,说明2组数据具有一定的吻合性。该模型可以作为鱼类增殖站养殖废水水质的一种估算方法。

An aquaculture wastewater quality model , based on the analysis of the mass balance and water balance of the fish breeding station , was developed as an evaluative tool to estimate the water quality of fish breeding stations.The estimation formulas of total nitrogen（TN）, total phosphorous（TP） and suspended solids（SS） with the bait weight（W） and the water inflow（Q） were shown as follows：CTN =0.01024W＆#183; Q-1, CTP=0.00045W· Q-1, CSS =0.277W· Q-1 , and the estimation values of TN , TP and SS in the wastewater of Luding fish breeding station were CTN =0.395 mg/L, CTP =0.017 mg/L, CSS =10.68 mg/L, respectively, which agree well with the monitoring results （Sig.〉0.05）, indicating that there were no significant difference between the estimation values and monitoring values.Therefore, the model was an effective estimation tool of aquaculture wastewater quality for fish breeding stations.
