Process for reducing organic matters and chromaticity by oxidizing cyclized wastewater

The invention relates to the technical field of cyclization wastewater, in particular to a process for reducing organic matters and chromaticity by cyclization wastewater oxidation, the process adopts hypochlorite to treat cyclization wastewater, and the process comprises the following steps: adding acid to adjust the pH value of the cyclization wastewater to 8 +/-1; the reaction temperature is controlled to be 60 +/-5 DEG C, the reaction time is controlled to be 3 +/-0.5 hours, the adding proportion of the pypocholoride is 0.2%-0.6%, and the proportion is the mass percent of the added pypocholoride relative to the mass of the cyclization wastewater. The process has the advantages of low equipment investment, low material consumption and low energy consumption, can obviously improve the chromaticity of liquid calcium and calcium chloride dihydrate finished products, and has good economic benefits. 本发明涉及环化废水技术领域，尤其涉及一种环化废水氧化消减有机物与色度工艺，工艺采用次氯酸盐处理环化废水，包括以下步骤：加入酸调节环化废水的pH值为8±1；而后加次氯酸盐，控制反应温度为60±5℃、反应时间在3±0.5小时，所述
