技术领域technical field

As the main skeleton material of tires, the demand for steel cords continues to increase, resulting in an increasing demand for steel cord drawing lubricants. . Wire drawing lubricant plays the role of lubrication, cooling, cleaning and so on. As the working time of the lubricant increases, the free acid, alkali, heavy metals and other pollutants in the wire drawing lubricant gradually accumulate, which reduces the lubricating ability of the wire drawing fluid, and when the situation is serious, it will cause the wire to break, so the lubricant needs to be replaced, resulting in Lubricant wastewater.

拉丝润滑剂废水的成分包括合成油、乳化剂、防锈剂、表面活性剂等。由于在拉丝工艺过程中有大量重金属带入,因此含有高浓度的锌与络合铜,废水的COD浓度高达40000~80000mg/L。The components of wire drawing lubricant wastewater include synthetic oil, emulsifier, rust inhibitor, surfactant, etc. Due to the large amount of heavy metals brought in during the wire drawing process, it contains high concentrations of zinc and complexed copper, and the COD concentration of the wastewater is as high as 40,000-80,000 mg/L.

拉丝润滑剂废水成分复杂,污染物浓度高,处理难度大,该种废水的处理是钢帘线企业污染治理的难题。The composition of wire drawing lubricant wastewater is complex, the concentration of pollutants is high, and the treatment is difficult. The treatment of this kind of wastewater is a difficult problem in the pollution control of steel cord enterprises.

拉丝润滑剂废水对环境和人体健康具有极大的危害性,目前该类废水的处理方法大致可分为物理法、物理化学法、化学法、生物法等,但采用传统的单一物理、化学、生物法均不能达到有效的处理效果。Drawing lubricant wastewater is extremely harmful to the environment and human health. At present, the treatment methods of this type of wastewater can be roughly divided into physical methods, physicochemical methods, chemical methods, biological methods, etc., but the traditional single physical, chemical, Biological methods cannot achieve effective treatment effects.

一种采用上述高浓度拉丝润滑剂废水处理系统进行废水处理的方法,具有如下步骤:A method for wastewater treatment using the above-mentioned high-concentration wire drawing lubricant wastewater treatment system has the following steps:

①废水通过进水管进入废水调节池调节水质和水量。①Wastewater enters the wastewater regulating tank through the water inlet pipe to adjust the water quality and quantity.

②调节后的水通过破乳池底部的进水管进入破乳池,酸液添加和pH值测控系统调节废水的pH值为3-4,在酸性条件下废水中的乳化油结构被破坏,变为悬浮态。②The adjusted water enters the demulsification tank through the water inlet pipe at the bottom of the demulsification tank. The acid solution addition and pH value measurement and control system adjust the pH value of the wastewater to 3-4. Under acidic conditions, the emulsified oil structure in the wastewater is destroyed and becomes in a suspended state.

③然后废水通过进水管进入臭氧氧化气浮池的中下部;位于臭氧氧化气浮池布水管下方的曝气盘产生大量细小气泡,臭氧把废水中的大分子物质氧化成易于吸收和吸附的小分子物质,同时曝气盘产生的细小气泡与油渣粘附形成混合体在浮力作用下上升,在臭氧氧化气浮池分离区三相分离器的作用下,混合体上升至油渣区,在油渣刮板的作用下,油渣进入油渣槽并被清理外运;分离处理后的水在臭氧氧化气浮池三相分离区导流板作用下进入臭氧氧化气浮池集水区,通过溢水堰、出水管和连接管进入混凝还原沉淀池的进水管。③ Then the waste water enters the middle and lower part of the ozone oxidation air flotation tank through the water inlet pipe; the aeration plate located below the water distribution pipe of the ozone oxidation air flotation tank produces a large number of fine air bubbles, and the ozone oxidizes the macromolecular substances in the wastewater into small molecular substances that are easy to absorb and adsorb At the same time, the fine air bubbles produced by the aeration disc adhere to the oil residue to form a mixture that rises under the action of buoyancy. Under the action of the plate, the oil residue enters the oil residue tank and is cleaned and transported; the separated water enters the water collection area of the ozone oxidation air flotation pool under the action of the guide plate in the three-phase separation area of the ozone oxidation air flotation pool, and passes through the overflow weir, outlet The water pipe and connecting pipe enter the water inlet pipe of the coagulation reduction sedimentation tank.

④废水通过混凝还原沉淀池搅拌混合区底部的废水进水管进入混凝还原沉淀池,废水与来自药液添加系统的混凝剂和还原剂混合,利用设置在搅拌区中部的搅拌装置进行搅拌;混凝还原反应后的废水进入废水流道,调节废水的pH值为9-10,调节后的废水进入沉淀区,废水中的铜、锌在碱性条件下生成沉淀物,沉淀区的三相分离器实现泥水分离;污泥在重力的作用下下沉到混凝还原沉淀池沉淀区的下部,通过底部的沉淀物排放阀排出;废水通过溢水堰、出水管和连接管进入高级氧化反应沉淀池的进水管。④Wastewater enters the coagulation reduction sedimentation tank through the wastewater inlet pipe at the bottom of the stirring and mixing zone of the coagulation reduction sedimentation tank, and the wastewater is mixed with the coagulant and reducing agent from the liquid medicine addition system, and stirred by the stirring device set in the middle of the stirring zone The waste water after the coagulation reduction reaction enters the waste water flow channel, and the pH value of the waste water is adjusted to be 9-10. The phase separator realizes the separation of mud and water; the sludge sinks to the lower part of the sedimentation area of the coagulation reduction sedimentation tank under the action of gravity, and is discharged through the sediment discharge valve at the bottom; the waste water enters the advanced oxidation reaction through the overflow weir, outlet pipe and connecting pipe The inlet pipe of the sedimentation tank.

⑤混凝还原沉淀后的水通过高级氧化反应沉淀池的进水干管、布水管进入高级氧化反应沉淀池,海绵铁填料筒中的过氧化氢、海绵铁盐反应产生大量活泼的羟基自由基,破坏废水中污染物的结构,废水中的污染物被氧化分解,氧化分解后的废水通过溢水堰、出水管和连接管进入反流式曝气生物滤池的进水管。污泥等沉淀物在重力的作用下下沉到高级氧化反应沉淀池的下部,通过底部的沉淀物排放阀排出。⑤The water after coagulation reduction and precipitation enters the advanced oxidation reaction sedimentation tank through the main water inlet pipe and water distribution pipe of the advanced oxidation reaction sedimentation tank. The hydrogen peroxide and sponge iron salt in the sponge iron packing tube react to produce a large number of active hydroxyl radicals. The structure of the pollutants in the wastewater is destroyed, the pollutants in the wastewater are oxidized and decomposed, and the oxidized and decomposed wastewater enters the inlet pipe of the reverse flow biological aerated filter through the overflow weir, the outlet pipe and the connecting pipe. Sediment such as sludge sinks to the lower part of the advanced oxidation reaction sedimentation tank under the action of gravity, and is discharged through the sediment discharge valve at the bottom.

⑥废水通过进水管、布水管进入反流式曝气生物滤池的下流区,曝气管产生的空气与废水在填料中交汇发生生化反应,同时填料对废水进行过滤,废水通过折流板后进入上流区,在填料中发生生化反应,同时填料对废水进行过滤,下流区和上流区产生的污泥下沉到污泥区,通过污泥区底部的污泥排放阀排放出去,反流式曝气生物滤池处理后的水通过溢水堰流出,实现达标排放。⑥Wastewater enters the downstream area of the counterflow biological aerated filter through the water inlet pipe and water distribution pipe. The air generated by the aeration pipe and the waste water meet in the filler to undergo a biochemical reaction. At the same time, the filler filters the waste water. After the waste water passes through the baffle plate Entering the upstream area, biochemical reactions occur in the packing, and the packing filters the waste water at the same time. The sludge generated in the downstream area and the upstream area sinks to the sludge area and is discharged through the sludge discharge valve at the bottom of the sludge area. The water treated by the biological aerated filter flows out through the overflow weir to achieve standard discharge.

⑦混凝还原沉淀池、高级氧化反应沉淀池、反流式曝气生物滤池排出的污泥经浓缩、脱水后外运。⑦ The sludge discharged from the coagulation reduction sedimentation tank, advanced oxidation reaction sedimentation tank, and counterflow biological aerated filter is concentrated and dehydrated before being transported abroad.
