本发明提供了一种用于净化水的聚合铁的改进 性生产工艺。其主要内容是以廉价硫酸亚铁为原料， 用氯酸钾作氧化剂，在酸性介质情况下生产液体和固 体聚合铁。其特点是工艺简单、原料易得、净化效果 好，不存在二次污染问题。不但可以净化污水还可以 净化饮用水。制得的固体聚合铁便于运输和贮存，为 扩大聚合铁的使用范围提供了极为方便的条件。The present invention provides an improvement in polymeric iron for water purification sexual production process. Its main content is to use cheap ferrous sulfate as raw material, Potassium chlorate is used as an oxidant to produce liquid and solid in acidic medium body polymerized iron. It is characterized by simple process, easy access to raw materials, and high purification effect. Well, there is no secondary pollution problem. It can not only purify sewage but also Purify drinking water. The prepared solid polymeric iron is convenient for transportation and storage, and is Expanding the scope of use of polymerized iron provides extremely convenient conditions.
Description
The present invention is a kind of production technique of water scavengine agent.
For purifying waste water and tap water, mostly adopt water purification agents such as Tai-Ace S 150, aluminium chlorohydroxide and polymerization iron both at home and abroad at present, under the contrast, it is with low cost that polymerization iron has, applied widely, and advantages such as good purification are generally adopted by people.But the existing production technique of polymerization iron is complicated, and the reaction times is longer, and production cost is higher.The patent application of a ferrous system of polymerized water purifier production method was disclosed on December 14th, 1.This application is utilized the ferrous sulfate waste liquid to add hydrogen peroxide and is made oxygenant, makes mother liquor with squama iron sheet, hydrochloric acid, ammoniacal liquor, again oxygenant and mother liquor reaction is made polymerization iron, and this method raw material is easy to get, and cost is lower.But technology is still complicated, needs medicament more, and the reaction times still needs more than 12 hours, and is that liquid product inconvenience is transported and stored.
For solving the deficiency that the existing production method of polymerization iron exists, satisfy present heavy demand to water scavengine agent.The present invention releases a kind of improved processing method.Not only liquid polymeric iron can be produced, and solid polymerization iron can also be produced.This polymerization iron does not have secondary pollution, but purifying drinking water, good purification.
Details are as follows for the technology of production polymerization iron of the present invention:
One, raw material: industrial ferrous sulfate, industrial sulphuric acid, Potcrate.
Two, equipment: reactor, vacuum pump, condenser, disintegrating machine, drying baker.
Three, processing method: at first used ferrous sulfate is chemically examined, measured ferrous (Fe
++) content, so that grasp the consumption of oxygenant chloric acid potassium.In reactor, add entry and sulfuric acid.Water and vitriolic amount are decided according to the amount of the polymerization iron that will produce.One ton of polymerization iron of general production need add 100～200 kilograms of entry, needs to add 50～100 kilograms in sulfuric acid.Add ferrous sulfate again, under stirring state, add Potcrate slowly.The amount of Potcrate is decided according to the amount of ferrous sulfate, and the ratio control of general ferrous sulfate and Potcrate is 13～15: the 1(weight ratio).Finish along with Potcrate adds, brown high price iron generates, and reaction is just basic to be finished, and has just obtained the gluey polymerization iron of liquid.If place to use and production site are nearer, and do not need long storage, this colloidal liquid can directly be disposed of sewage and tap water as water conditioner, as being river water cleaning tap water.Transport for long-distance if desired and store, this liquid product also can continue to be processed into solid phase prod, and concrete grammar is as follows: will liquid polymeric iron move in the evaporating kettle and carry out reduction vaporization, vaporization temperature is 40～60 ℃, and vacuum degree control is at 30～50 mmhg.Take out during near doing to be evaporated and add a part of crystal seed (solid polymerization iron) and be placed in the drying baker and dry, or put sun cured, obtain blocks of solid polymerization iron, just obtain polymerization iron finished product through disintegrating machine powder essence again.Can add also can obtain same effect for saving the reduction vaporization process into crystal seed.Yes that to add many more curing fast more for the amount of crystal seed, but will increase workload, grasps according to practical situation and be advisable.
The present invention has compared following advantage with the production method of existing polymerization iron:
1. good purification promptly can be used as sewage-treating agent, but yet purifying drinking water does not have the secondary pollution problem.
2. method is easy, and the reaction times is short, makes with medicament few.
3. can make solid phase prod is convenient to store and transportation.
Be that example illustrates processing method of the present invention to produce one ton of solid polymerization iron below.
Ferrous sulfate (Steel Mill adds waste pickle liquor with the squama iron sheet and makes) with cheapness is a raw material, contains ferrous (Fe through chemical examination
++) 20%.Earlier in reactor, add 100 kilograms of entry, add 50 kilograms in sulfuric acid.Add 1000 kilograms in ferrous sulfate again, under continuous stirring state, add 73 kilograms in Potcrate slowly, treat that the Potcrate adding finishes, and promptly obtains brown polymerization iron liquid product.Liquid polymeric iron is moved in the evaporating kettle again and carry out reduction vaporization, vaporization temperature is 50 ℃, and vacuum tightness is 40 mmhg.The nearly liquid of doing of evaporation is shifted out adding 50 kilograms of crystal seeds (solid polymerization iron), be placed in the drying baker and dry, dispatch from the factory with pure packing of disintegrating machine powder then.
