齐齐哈尔氧化塘改造前、后净化功能对比分析

THE TREATMENT ABILITY OF OXIDATION POND OF THE CITY QIQIHAR COMPARE AND ANELYSE BEFORE AND AFTER RECONSTRUCTION

本文根据齐齐哈尔氧化塘改造前、后的现场监测数据,分别统计出改造前(自然状态下)和改造后(厌氧塘、兼性塘、生态塘)在冬季和夏季处理城市混合污水COD、BOD_6、SS的体积负荷、面积负荷和这三项指标随距离降解的数学模型;统计结果表明,改造后的氧化塘处理有机废水的能力明显提高;冬季(冰封期),塘内仍有一定的净化作用,为我国北方地区应用氧化塘技术处理城市混合污水提供了参数。

This article was according to the oxidation pond of the city Qiqihar the montoring data on hand get from the before and after the reconstruction of the model works of the northern district in our country. To make a separate statistics about the before reconstruction (under the natural condition) and the after reconstruction (anaerobic pond, facultative pond, ecological pond), the organic load treated in the urban mixing sewage (dimension carrying capacity, area carrying capacity), and the COD, BOD_5, SS degradation mathematic model in winter and summer; the result of the statistics shows that, after the reconstruction of the oxidation pond, the treatment ability of the organic waste water was visibly promoted, in winter (ice frozen period) the pond also to have some ability of purifying effect; for the applying the technology of the oxidation pond to treat the urban mixing sewage in the northern district in our country, it provided the consultation data, the result of the comparison and analysis of the before and after reconstruction of the oxidation pond, the ablity of the organic waste water treatment was apparently promoted.
