【摘要】 以腐植酸（HA）模拟水为试验水样，通过混凝试验和观察法，对比研究液态双果皮混凝剂（ADFP）在低温（4℃）和室温（25.0～30.5℃）下的储存稳定性，并对比研究其液态与固态的除浊脱色效果。结果显示，低温下储存稳定性优于室温，室温下防腐剂添加量为0、 0.01%和0.05%时，其除浊和脱色效果分别于5、 11和20 d后大幅下降，而低温下同等防腐剂添加量下效果下降的天数则分别延长了10、 14和35 d。ADFP混凝机理出现了天然有机物和微生物的综合效果。液态ADFP的除污染效果优于热干固态，随着投药量的增加，液态ADFP的除浊率和脱色率始终维持在90%左右和80%以上，比热干固态分别高9%和10%左右。更多还原

【Abstract】 Taking humic acid(HA) simulated water as the test sample, the storage stability of liquid dualpeel coagulant(ADFP) under low temperature(4 ℃) and room temperature(25.0-30.5 ℃), as well as its turbidity removal and decolorization efficiency in liquid and solid forms were comparatively studied through coagulation experiments and observation. The results showed that, storage stability was better under low temperature than at room temperature. At room temperature, when the preservative dosage were 0, 0.01%, and0.05%, the turbidity removal and decolorization effects decreased significantly after 5, 11, and 20 days,respectively. In contrast, under low temperature with the same preservative dosages, the periods before performance decline were extended by 10, 14, and 35 days, respectively. The coagulation mechanism of ADFP exhibited a combined effect of natural organic matters and microorganisms. The liquid form of ADFP demonstrated better pollution removal performance than the thermally dried solid form. As the dosage increased,the turbidity removal rate and decolorization rate of liquid ADFP remained around 90% and above 80%,respectively, which were approximately 9% and 10% higher than those of the thermally dried solid form.更多还原
