Description
一种船舶脱硫废水处理装置及方法 技术领域 Ship desulfurization wastewater treatment device and method
本发明涉及一种船舶脱硫废水处理装置及方法， 属于船舶脱硫废水处理领域。 背景技术 The invention relates to a ship desulfurization wastewater treatment device and method, and belongs to the field of ship desulfurization wastewater treatment. Background technique
根据 MARPOL公约附则 VI规定， 2015年 1月 1 日起， 航行在排放控制区（ECA) 的船只， 必须燃烧含硫量等于或小于 0.10% (m/m) 的低硫燃油， 同时允许船只使用 经批准的减排技术， 条件是 SO2排放等效于燃烧等于或小于 0.10%的低硫燃油。 According to Annex VI of the MARPOL Convention, vessels operating in the Emission Control Area (ECA) must burn low-sulfur fuels with a sulfur content equal to or less than 0.10% (m/m) from January 1, 2015, while allowing vessels to use Approved abatement technology, provided that SO 2 emissions are equivalent to burning low-sulfur fuels equal to or less than 0.10%.
由于石油资源紧缺， 低硫燃油价格高昂且供不应求， 船舶废气脱硫成为国内外研 究热点。 调查目前国内外已有报道的船舶废气脱硫装置发现， 除 Couple Systems公司 采用干法脱硫外， 其余均为湿法脱硫。 可见湿法脱硫是船舶废气脱硫的主流方式， 采 用湿法脱硫技术必然会产生脱硫废水。 而国际海事组织 （IMO) 对船舶废气清洁系统 的洗涤水排放指标做了严格的规定。 同时由于是船舶废气脱硫， 其脱硫废水排放又受 《船舶污染物排放标准》 的制约。 因此脱硫废水的处理， 是整个湿法船舶废气脱硫系 统中不可或缺的关键技术。 船舶废气脱硫技术属于新兴技术， 目前研究重点主要集中 于脱硫效率的提高及能耗的降低， 关于船舶废气脱硫废水处理的研究较少。 调查现有 国内外船舶废气脱硫装置， 鲜有脱硫废水处理工艺的详细介绍。 废水只是通过简单的 曝气氧化或旋流分离处理后进行排放或回用。 Due to the shortage of petroleum resources, low-sulfur fuels are expensive and in short supply, and ship exhaust gas desulfurization has become a research hotspot at home and abroad. Investigate the ship exhaust gas desulfurization devices that have been reported at home and abroad. Except for the use of dry desulfurization by Couple Systems, the rest are wet desulfurization. It can be seen that wet desulfurization is the mainstream way of desulfurization of marine exhaust gas, and desulfurization wastewater is inevitably produced by wet desulfurization technology. The International Maritime Organization (IMO) has strict regulations on the wash water discharge targets for ship exhaust gas cleaning systems. At the same time, due to the desulfurization of the ship's exhaust gas, the desulfurization wastewater discharge is subject to the “Contamination Standard for Ship Pollutants”. Therefore, the treatment of desulfurization wastewater is an indispensable key technology in the entire wet-process marine desulfurization system. The ship exhaust gas desulfurization technology is an emerging technology. At present, the research focus is mainly on the improvement of desulfurization efficiency and the reduction of energy consumption. There are few studies on the treatment of ship exhaust gas desulfurization wastewater. Investigate the existing domestic and foreign ship exhaust gas desulfurization devices, and introduce a detailed description of the desulfurization wastewater treatment process. The wastewater is discharged or reused only after simple aeration oxidation or cyclone separation.
镁基-海水法（M&S )是一种高效的船舶废气脱硫方法。废气进入脱硫塔与喷淋液 接触反应， 气体中的污染物， 如： 颗粒物（PM)、 SO2、 NO2等部分被喷淋液吸收， 形 成液态污染物。 其中 PM—部分悬浮于水中， 另一部分溶解形成多环芳烃 （PAHs); 未燃尽的燃料油随废气一起进入到废水中， 增加了废水的总油含量； SO2溶于水并与 脱硫剂中 Mg2+反应生成难溶物 MgSO3 ; NO2溶于水中形成 NO2—及 NO3—。 pH值、 COD、 浊度 （主要由 MgSO3及 PM贡献）、 总油、 PAHs、 NOx—均为排放指标中要求控制的污 染物。 Magnesium-seawater method (M&S) is an efficient method for desulfurization of marine waste gas. The exhaust gas enters the desulfurization tower and contacts with the spray liquid. The pollutants in the gas, such as: particulate matter (PM), SO 2 , NO 2 and the like are absorbed by the spray liquid to form liquid pollutants. Among them, PM is partially suspended in water, and the other part is dissolved to form polycyclic aromatic hydrocarbons (PAHs); unburned fuel oil enters the wastewater along with the exhaust gas, increasing the total oil content of the wastewater; SO 2 is soluble in water and desulfurizing agent The Mg 2+ reaction forms a poorly soluble MgSO 3 ; NO 2 is dissolved in water to form NO 2 — and NO 3 —. The pH, COD, turbidity (MgSO 3 and the main contribution of PM), the total oil, PAHs, NO x - the Control of emission targets are required.
