摘要
污水处理时絮凝参数可在一定范围内进行有效的调节以提高絮凝效果。研究了以交联胍胶为主的压裂返排废液在联合站污水中含量为7%时,温度、p H值、絮凝剂加药量和沉降时间对掺入采出水絮凝效果的影响。实验结果表明,升高温度有利于絮凝效果的提高,p H值为9时絮凝效果较好,沉降时间需要4 h以上。
When sewage flocculation processed,its flocculation parameters can be effectively regulated within a certain range. This paper studies the predominantly cross-linked guanidine gum fracturing flow back liquid when its content in the sewage was 7%, and the effect of temperature,p H value,dosage of flocculent and settling time on flocculation efficiency of produced water were studied.The increase of the temperature is conducive to the improvement of the flocculation effect, and when the p H value is 9, the flocculation effect is better and the settling time needs more than 4 hours.
