Definitions
- the invention belongs to the technical field of sewage treatment, and more specifically to a method for deep processing biochemical tail water of coking wastewater.
- Coking wastewater is a wastewater generated in the process of high-temperature coking, gas purification and chemical product refining of raw coal. Its composition is complex, and with the difference of raw coal, cognac temperature and chemical by-product recovery methods, the composition of wastewater changes greatly.
- Coking wastewater generally contains ammonia nitrogen, cyanide, thiocyanide, phenols and other organic pollutants such as polycyclic aromatic hydrocarbons, nitrogen-containing, oxygen and sulfur heterocyclic compounds. These persistent pollutants pose a greater hazard to the ecological environment, and most polycyclic and heterocyclic compounds are continuously converted and carcinogenic. Therefore, the treatment of coking wastewater is a serious problem faced by various countries at home and abroad. At present, most coking plants discharge the coking wastewater produced after dephenolation pretreatment and biochemical treatment.
- the biochemical oxygen demand (BOD) in coking wastewater can meet the national wastewater secondary emission standard, but the color and chemical oxygen demand (COD) are generally exceeded, which does not meet the national emission standards.
- COD color and chemical oxygen demand
- the above problems can be solved by using advanced oxidation method, activated carbon adsorption method, etc., but the high cost and small processing amount limit its wide application. Therefore, it is difficult and urgent to solve the problem that the advanced treatment technology of coking wastewater with simple process, low cost and stable effect is urgently needed.
- Iron oxides and manganese oxides are used to remove certain heavy metals (Zn, Cd, M, Pb, etc.) and inorganic anionic contaminants (arsenate, fluoride, perchlorate, etc.) in solution, which is widely used in many literatures and patents. It has been documented. Some organic matter in the wastewater can form a coordination complex with hydrated iron oxide or hydrated manganese oxide to form selective adsorption, which makes it possible to treat organic wastewater with iron oxide or manganese oxide nanomaterials. However, achieving standard discharge after coking wastewater treatment is still a difficult problem in the art.
- the present invention provides a method for deeply treating the biochemical tail water of coking wastewater, which can be processed at a lower cost, in view of the current situation that the coking wastewater after biochemical treatment cannot achieve the standard discharge.
- the effluent COD stabilized to below 70 mg / L, the chromaticity stability fell below 20 times.
- a method for deeply treating biochemical tail water of coking wastewater comprising the following steps:
- the effluent from the secondary settling tank of the coking wastewater biochemical treatment system flows into the flocculation agitation tank, and the ferric sulfate (PFS) and polyacrylamide (PAM) are added to mix the raw water and the flocculant.
- the method of adding polyferric sulfate (PFS) and polyacrylamide (PAM) is wet addition.
- the concentration of polyferric sulfate (PFS) solution is 2-10%, and the dosage is 5-25 L/m 3
- the concentration of the polyacrylamide (PAM) solution is 0.05-0.2%, and the dosage is 5-20 L/m 3 .
- the stirring speed of the flocculation agitating tank is 200-300 rpm, and the mixing time is 2-6 min.
- the mixed liquid obtained in the step (A) is flowed into the flocculation reaction tank to carry out flocculation reaction, and large flocculated particles are formed by compressing the electric double layer, the adsorption electric neutralization, the adsorption bridging, the net trapping, and the like, and removing the water. Colloidal particles, non-soluble COD and other contaminants.
- the stirring speed of the flocculation reaction tank is 50-100 rpm, and the reaction time is 20-60 min.
- the flocculation reaction mixture obtained in the step (B) is flowed into the sedimentation tank for solid-liquid separation.
- the sedimentation time of the sedimentation tank is 30-60 min.
- step (D) After filtering the supernatant obtained in step (C), at 5-35 °. Under the condition, the flow rate of 4-10 BV/h (BV is the bed volume) is passed through the adsorption tower packed with nanocomposites, so that the soluble organic matter and the small amount of reducing inorganic substances which are difficult to be biodegraded in the wastewater are effectively adsorbed in the nanometer. On the material; the amount of wastewater treated per batch is 500-1000 BV. The COD of the adsorbed water is less than 70 mg/L and the chroma is less than 20 times.
- the nanocomposite of the present invention has a quaternized nanoporous spherical polystyrene as a basic skeleton, and is loaded with nano iron oxide or manganese oxide particles. It can be a composite material loaded with manganese oxide nanoparticles DA-HMO (produced by Jiangsu Yongtai Environmental Protection Technology Co., Ltd.) or a composite material loaded with iron oxide nanoparticles (DA-HFO (produced by Jiangsu Yongtai Environmental Protection Technology Co., Ltd.). Preferred among these are composite materials DA-HMO carrying manganese oxide nanoparticles.
- step (F) Concentrate the high concentration desorption solution obtained in step (E), send it to incineration or use it to produce coal water slurry, and use low concentration desorption solution to prepare sodium hydroxide solution for the next batch of desorption operation. .
- the general coking wastewater treatment method can only process COD to about 100 mg/L, the efficiency is not high, and the treatment amount is small, and the decolorization ability is poor.
- this method is due to the aroma of oxide nanoparticles to monocyclic and polycyclic Group compounds, heterocyclic compounds containing nitrogen, sulfur, oxygen, organic components such as phenols, and high adsorption selectivity, high adsorption efficiency, and resin-based Donnas membrane effect of reducing inorganic substances such as cyanide and thiocyanide, Excellent COD and chroma removal.

Description
一种深度处理焦化废水生化尾水的方法 技术领域
本发明属于污水处理技术领域,更具体的说是一种深度处理焦化废水生化尾水的 方法。
背景技术
焦化废水是在原煤高温干熘、煤气净化和化工产品精制过程中产生的废水,其成 分复杂, 且随着原煤、干熘温度和化工副产品回收方式等的不同, 废水的成分发 生很大变化。 焦化废水一般含有氨氮说、 氰化物、硫氰化物、 酚类以及其他有机污 染物如: 多环芳香烃、 含氮、 氧和硫杂环化合物等。 这些持久性污染物对生态环 境造成较大的危害,且大多数多环和杂环化书合物可不断转化并具有致癌性。因此, 焦化废水的处理是目前国内外各个国家面临的严峻的问题。 目前, 大多数焦化厂 对产生的焦化废水经过脱酚预处理、生化处理后即进行排放。焦化废水中生化需 氧量 (BOD) 能达到国家废水二级排放标准, 但色度、 化学需氧量 (COD) 等 普遍超标, 达不到国家要求的排放标准。采用高级氧化法、活性炭吸附法等可以 解决上述问题, 但成本高、 处理量小限制了其广泛应用。 因此, 寻求工艺简单、 成本低廉、 效果稳定的焦化废水深度处理技术是目前较难且迫切需要解决的问 题。
铁氧化物和锰氧化物用于去除溶液中某些重金属 (Zn、 Cd、 M、 Pb等) 及无机 阴离子污染物 (砷酸根、 氟离子、 高氯酸根等), 这在很多文献及专利中已有记 载。废水中某些有机物可以与水合氧化铁或水合氧化锰形成配位络合物, 形成选 择吸附,这使得采用铁氧化物或锰氧化物纳米材料处理有机废水成为可能。但对 于焦化废水处理后实现达标排放仍是本领域技术所需要面对的难题。
发明内容
1、 发明要解决的技术问题
为解决现有技术存在的问题,针对目前经生化处理后的焦化废水不能实现达标排 放的现状,本发明提供一种深度处理焦化废水生化尾水的方法,可以在较低的成 本下, 使处理后出水 COD稳定降至 70 mg/L以下, 色度稳定降至 20倍以下。
2、 技术方案
本发明的技术方案如下:
一种深度处理焦化废水生化尾水的方法, 包括以下步骤:
( A) 将焦化废水生化处理系统二沉池出水流入絮凝搅拌池, 投加聚合硫酸铁 (PFS)和聚丙烯酰胺(PAM),使原水与絮凝剂得以充分混合。聚合硫酸铁(PFS) 和聚丙烯酰胺 (PAM) 的投加方式均为湿式投加, 聚合硫酸铁 (PFS) 溶液的浓 度为 2-10%,投加量为: 5-25 L/m3;聚丙烯酰胺(PAM)溶液的浓度为 0.05-0.2%, 投加量为: 5-20 L/m3。 絮凝搅拌池中搅拌浆的转速为 200-300 rpm, 混合时间为 2-6 min。
(B) 将步骤 (A) 得到的混合液流入絮凝反应池, 进行絮凝反应, 通过压缩双 电层、 吸附电中和、 吸附架桥、 网捕等物理化学作用形成大的絮凝颗粒, 去除水 中胶体颗粒、 非溶解性 COD 等污染物。 絮凝反应池中搅拌浆的转速为 50-100 rpm, 反应时间为 20-60 min。
(C) 将步骤 (B) 得到的絮凝反应混合液流入沉淀池, 进行固液分离。 沉淀池 的沉淀时间为 30-60 min。
(D) 将步骤 (C) 所得上清液过滤后, 在 5-35 °。条件下, 以 4-10 BV/h (BV 为床层体积)的流速通过装填有纳米复合材料的吸附塔, 使废水中难以生物降解 的溶解性有机物和少量还原性无机物被有效吸附在纳米材料上;每批次废水处理 量为 500-1000 BV。 吸附出水的 COD小于 70 mg/L, 色度小于 20倍。
本发明中所述纳米复合材料以季铵化的纳米孔球形聚苯乙烯为基本骨架、负载纳 米铁氧化物或锰氧化物颗粒。 它可以是负载锰氧化物纳米粒子的复合材料 DA-HMO (江苏永泰环保科技有限公司生产), 也可以是负载铁氧化物纳米粒 子的复合材料 DA-HFO (江苏永泰环保科技有限公司生产)。 其中优选的是负 载锰氧化物纳米粒子的复合材料 DA-HMO。
(E) 当吸附达到穿透点时 (COD超过 70 mg/L或色度超过 20倍) 停止吸附, 用 2- 10%的氢氧化钠水溶液作为脱附剂,在 40-85 温度下以 0.5-2 BV/h的流速 进行脱附再生。
(F) 将步骤 (E) 得到的高浓度脱附液浓缩后, 外送焚烧或者用于生产水煤浆, 低浓度脱附液用于配制氢氧化钠水溶液套用于下一批脱附操作。
一般的焦化废水深度处理方法, 其 COD仅能处理至 100 mg/L左右, 效率不高, 且处理量小, 脱色能力较差。但本方法由于氧化物纳米颗粒对单环及多环的芳香
族化合物, 含氮、 硫、 氧的杂环化合物, 酚类等有机成分和氰化物、 硫氰化物等 还原性无机物的高吸附选择性、 高吸附效率以及树脂基的 Donnas膜效应, 表现 出优异的 COD及色度去除效果。
3、 有益效果
本发明的有益效果在于: 1、 对生化处理后的焦化废水进行深度处理后, 在进水 COD为 160 mg/L, 色度为 80倍的条件下, 出水 COD<70 mg/L, 色度 <20倍, 达到污水综合排放标准 (GB8978-1996) —级标准; 2、 处理量大, 在保证上述 处理效果的条件下, 可处理 500-1000床层体积的焦化尾水; 3、 纳米复合材料再 生性能良好, 机械强度高, 可重复使用。 综上所述, 本发明操作工艺简单, 成本 低廉, 在产生环境效益的同时又产生经济效益。
