食品、纺织、染料、制药和化工/石油等行业，在生产过程中产生大量的含盐废水，含盐量有时高达15%~20%[2，3]。目前，对此类废水一般采用电解法、膜分离法、焚烧法和深井灌注法等技术处理。

Another remarkable characteristic of printing and dye the waste water is that the colour is high, is it adopt biological carbon pool is it is it deal with to decolour to go on to it , for activated carbon absorbent spent to design originally, active charcoal adsorption method to utilize porous active charcoal material make one or many kinds of material of waste water it absorbs to be that surface get rid of in active charcoal.

印染废水的另一显著特点就是色度高，本设计采用生物碳池对其进行脱色处理，所用的吸附剂为活性碳，活性炭吸附法就是利用多孔活性炭物质使废水中的一种或者多种物质被吸附在活性炭表面而去除的。

Experimental results show that the water velocity is that when the BV ammonia concentration of 50 mg, L - 1 simulation wastewater and 98 mg, L - 1 point of industrial wastewater, penetrate respectively C/C0 = 0.3 and 0.15, water column of natural zeolite could handle respectively; 126 BV, 43 BV Modified zeolite column can handle respectively 157 BV, water, and with 46 BV hydraulic load increases, zeolite column can reduce water treatment, The experiment was found to leak after 8 NaCl solution with zeolite desorption regeneration effect is good, low cost, regeneration of zeolite adsorption capacity decrescent, Test through dynamics analysis found that zeolite column of ammonia nitrogen adsorption fast.

实验结果表明，进水速度为2.72 BV时，通入氨氮浓度为50 mg·L-1的模拟废水和98 mg·L-1的工业废水，此时穿透点分别为C/C0=0.3和0.15时，得到天然沸石柱可处理水量分别为126 BV、43 BV；改性后沸石柱可处理水量分别为157 BV、46 BV，且随水力负荷增大，沸石柱可处理水量减小；试验还发现对泄露后沸石用8%NaCl溶液解吸再生效果好，成本低，再生后的沸石吸附容量变小；试验通过动力学分析发现沸石柱吸附氨氮速度较快。

The IR spectra of wastewater simulated with two typical fatty amine flotation collectors of decyl propyl ether amine and stearylamine were studied and the mechanism of degradation of fatty amine flotation collectors by the UV/H2O2/air oxidation method was discussed.

The invention discloses a disposing method of ammonia nitrogen waste water in the effluent disposal technological domain, which is characterized by the following: sieving heterotrophic nitrobacteria and aerobic denitrobacteria with stronger environment adaptive ability to nitrate and denitrate simultaneously; constructing mud nitrated and denitrated system to dispose waste water with nitrogen simultaneously to satisfy different DO densities.

为了解决同步硝化反硝化过程中菌种来源不明，调控困难，硝化和反硝化对DO浓度要求不同，在实际工程中难以实现同步硝化反硝化，本发明筛选出对环境有较强适应能力的异养硝化细菌和好氧反硝化细菌，采用异养硝化细菌和好氧反硝化细菌构建同步硝化反硝化污泥体系处理含氮废水，具有投资少，费用低，处理效果好，不仅去除废水中的氨氮，而且对总氮也有较高的去除率。

After the combined treatment performed at pH=4.0, using 2.5 of TiO2 for 8 min of adsorption and 20 mg/L of ClO2 for 2 min of oxidation, the treated sample was dischargeable under the existing discharge limits for dyeing wastewater; the starting COD was reduced from 750 mg/L to〈100 mg/L and that the wastewater color was reduced from 250 dilutions to 40 dilutions.

结果表明，对于COD为750mg／L、色度为250倍、SS为100mg／L的1000mL印染废水，当溶液pH为4.0、ClO2用量20mg／L、TiO2复合吸附剂用量2.5g、反应时间和吸附时间分别为2、8min时，处理后的废水COD＜100mg／L、色度〈40倍、SS＜70mg／L，达到了《纺织染整工业水污染物排放标准》（GB4287—92）排放要求。

It contains much turmeric ramification, which is dyeable and difficult dedradable surfactant, and its biodegradability is not good.
