聚氯化铝的絮凝过程简单说! 在污水处理职业中,絮凝法净化水是旧的固液分离方法之一,由于其适用性广、加工工艺简易、处理价格低一级特性,絮凝法现阶段仍广泛应用于饮用水、生活污水和工业污水处理中。 聚氯化铝(PAC)是一种优良的无机高分子絮凝剂.它在日本研制成功并与20世纪60年代投入工业化出产,是现阶段技术为老The flocculation process of polyaluminium chloride is simple. In the sewage treatment profession, flocculation is one of the oldest solid-liquid separation methods. Because of its wide applicability, simple processing technology and low treatment price, flocculation method is still cially strong adaptability to changes in water temperature, pH value, turbidityhe process of destabilizing colloidal particles. The solid particles o.

多年来聚合氯化铝已发展成为技术成熟、市场销量大的絮凝剂,并有逐步取代传统絮凝剂的趋势。西欧各国于1976年开始生产聚合氯化铝,用作工业污水处理絮凝剂;美国、加拿大已于1983年批准将其用于城市给水和工业污水处理。 聚合氯化铝是水处理混凝剂的常用药剂,水处理***,在饮用水、工业污水净化中有着至关重要的作用。我们常用到的聚合氯化铝含量有:26%、28%、30%。聚合氯化铝含量的不同,用途也不同,相对应的聚合氯化铝价格也不同
水污染的危害显而易见聚合氯化铝合理攻坚管理水污染.
国家对854个乡镇进行调查,每天的排放量达365.3亿吨.其间工业废水达成协议5.5亿吨. 这些废水绝大部分未经处理就直接排放, 污染了江河湖海. 水污染的危害是不是显而易见的.水体污染,水质恶化对人体健康和人类日子,聚合硫酸铁,出产都带来了严重的危害. Over the years, polyaluminium chloride has developed into a flocculant with mature technology and large market sales, and has gradually replaced the traditional flocculant. Western European countries began to produce polyaluminium chloride as flocculant for industrial sewage treatment in 1976, and the United States and Canada approved its use in urban water supply and industrial sewage treatment in 1983. Polyaluminium chloride (PAC) is a commonly used
主要用于去除无机磷、有机磷等水体中的总磷,有效解决水体富营养化,针对生活污水总磷太高难以处理进行研发的专项药剂。解决了其它除磷剂使用量大,除磷不***的问题
为了满足客户污水处理的需求,针对污水除磷的问题,自主研发了***处理含磷废水的除磷剂。主要为棕褐色液体,可适用与各种铝氧化、化学抛光、涂装、磷化等高含磷废水,除磷剂其优点为减少其他除磷药剂的用量,解决除磷不***的问题,并能节省处理成本。
除磷剂加药点的选择应用
预沉淀除磷——将除磷剂投在初沉池之前;
同步沉淀除磷——将除磷剂投加在生化反应池曝气区尾部或氧化沟末梢;
后沉淀除磷——将除磷剂投在二沉池后面(前提是设有终沉池)。
除磷剂污水处理的案例分享
金属表面处理厂,磷产生主要来源于金属除油磷化工艺,含正磷水量20m3/d间歇处理,浓度不稳定60-930mg/L不等。现场工艺有两级沉淀池。
除磷工艺
电镀废水处理厂,磷产生主要来源于化学镍水洗产生的偏磷(次磷),次磷磷水量180-240m3/d间歇处理,平均次磷浓度100mg/L。现场有两个40m3氧化池。
Mainly used to remove inorganic phosphorus, organic phosphorus and other total phosphorus in water body, effectively solve eutrophication of water body, for domestic sewage total phosphorus is too high to deal with research and development of special agents. It solves the problems of large amount of phosphorus removal agent and incomplete phosphorus removal.
In order to meet the needs of customers for wastewater treatment, in view of the problem of phosphorus removal from wastewater, we independently developed a professional phosphorus removal agent for phosphorus-containing wastewater
Case sharing of phosphorus removal wastewater treatment
In metal surface treatment plant, phosphorus production mainly comes from metal deoiling and phosphating process. The water content of po
When in use, the product can be directly added, or first added into the dissolving tank, the concentration is 10-20%, stirring, and pumping into the reaction tank.
The product is suitable for a wide range of pH values, especially in acidic conditi***. Its usage is about 100-1000 ppm (i.e. 0.1-1 kg/ton wastewater). According to the content of phosphate in wastewater, its dosage is different. The specific dosage is generally determined by experiments.
In the experiment, a certain amount of raw water was taken, the product (such as 500 ppm) was added, the pH value of wastewater was adjusted to 7-8, a small amount of PAM was added to flocculate and precipitate, and the supernatant was filtered to determine the content of phosphorus. (if you need to deal with heavy metals, use supernatant for two times.)
Conversion of dosing units: 500ppm =500mg/L=0.5g/L =0.5 =0.5kg/ wastewater
除磷剂投加
于10月25日-11月3日进行八天中试,采用亚铁除磷剂(破络剂换包)和配使用,可将总磷将至0.5-1.3mg/L(客户要求2以下),吨水成本降至7.73元(双+除磷剂),比客户原本投加量省了将近4.5-5元吨水成本。
