Abstract
The invention discloses a preparation method of an urban domestic sewage disinfectant, and the urban domestic sewage disinfectant product belongs to the field of disinfectants; the urban domestic sewage disinfectant product is prepared from potassium ferrate, bromo-3-chloro-5,5-dimethylhydantoin and pure water as raw materials by mixing at certain temperature. The advantages of the preparation method are that: used equipment is less, production process is simple, investment is low, product production and use are harmless to the human body; the urban domestic sewage disinfectant product is an urban domestic sewage disinfectant, can fully meet the primary treatment disinfection requirements of urban domestic sewage, has the capability of killing a variety of bacteria and viruses and removing ammonia nitrogen and phosphorus in the sewage, and is good in flocculation effect; the urban domestic sewage disinfectant product is compounded by the potassium ferrate and the bromo-3-chloro-5,5-dimethylhydantoin to achieve synergistic effect, but the compounded urban domestic sewage disinfectant product is slightly poor in stability, and needs to be immediately prepared when using.
Description
Technical field
The invention belongs to disinfectant field, relate in particular to a kind of compound method of city domestic sewage disinfectant.
Background technology
The source of city domestic sewage comprises: kitchen waste water, bath sewage, cesspool sewage, wash water etc., and its composition is mainly the fine suspension of high concentration, and B/C is larger, and Nitrogen-and Phosphorus-containing is higher.Municipal sewage treatment is generally according to the utilization of urban sewage or emission direction and consider the natural purifying ability of water body, determine degree for the treatment of and the corresponding treatment process of sewage, sewage after processing, no matter for industry, agricultural or recharge recharge of groundwater, all must meet the relevant water standard that country issues.Pollutant in sewage forms very complicated, usually needs above several method combination, just can reach processing requirements, by degree for the treatment of, divides, and can be divided into one-level, secondary, tertiary treatment process.Sewage coagulation is pretreatment; Two stage treatment is main body, and the sewage after processing generally can reach discharge standard; Tertiary treatment is advanced treating, and effluent quality is better, even can reach drinking water quality standard, but disposal cost is high.Disinfecting when product of the present invention is mainly used in the coagulation of sewage, the primary raw material of use is potassium ferrate, auxiliary material is BCDMH and water.Potassium ferrate is a kind of novel non-chlorine high effect disinfectants, there is efficient disinfective action, its molecular weight is 198.05, outward appearance is the glossy powder of mulberry, stable in dry air below 198 ℃, the very easily water-soluble light violet magenta solution that forms, after standing, can decompose and emit oxygen, and be settled out hydrated ferric oxide, potassium ferrate all has extremely strong oxidisability under acid condition or alkali condition, can be widely used in the oxidation of water and waste water, sterilization, sterilization, when pH value is 6-6.5, every premium on currency adds potassium ferrate 6mg-10mg, normal temperature can be killed pathogenic bacteria in water body in lower 30 minutes, Escherichia coli, typhoid bacillus and virus, every premium on currency adds in the waste water removed of potassium ferrate 10mg-20mg 86% ammonia nitrogen and 75% phosphorus, potassium ferrate also has good flocculation simultaneously, do not produce any poisonous, harmful material.The molecular weight of auxiliary material BCDMH is 241.5, fusing point is 158-162 ℃, outward appearance is white powder, BCDMH is the special disinfectant of a kind of performance, be mainly used in the sterilization of water treatment and water, especially except algae powerful in function, can be used for disinfecting, deodorizing, the sterilization bleaching of various water treatments, in agricultural, can be used for the aspects such as flowers and seed disinfection, sterilization, fruit freshness preserving.Product of the present invention is a kind of city domestic sewage disinfectant, can fully meet the demand of city domestic sewage coagulation sterilization, has the various bacteria of killing, virus, the ammonia nitrogen in removal waste water and the ability of phosphorus, and flocculating effect is good.Use potassium ferrate and BCDMH composite, to reach the effect of synergy, but composite city domestic sewage disinfectant stability is slightly poor, need join and use.
Summary of the invention
The problem that the present invention mainly solves is to provide a kind of compound method of city domestic sewage disinfectant, and it is raw material that the method be take potassium ferrate, BCDMH, water, and the blending by a certain temperature made finished product afterwards.The advantage of this production method is: device therefor is few, it is little to invest, production technology is simple, the production of product with use all harmless, the needs that can fully meet the sterilization of city domestic sewage coagulation, the present invention uses the weight proportion of raw material to be: potassium ferrate 0.8%-0.9%, BCDMH 0.1-0.2%, pure water 99%.
The present invention can be achieved through the following technical solutions:
A compound method for city domestic sewage disinfectant, its feature consists of following steps:
(1) pure water of formula ratio is sent into agitator tank, temperature is increased to 20 ℃-25 ℃, add while stirring the potassium ferrate of formula ratio, be stirred to whole dissolvings.
(2) be cooled to 10 ℃-15 ℃, add the BCDMH of formula ratio, after stirring, get product.
(3) using method of this city domestic sewage disinfectant is: this agent and city domestic sewage are added in sewage by the consumption of 1:1000, and standing 1-3 hour stirs.
The purity of the potassium ferrate that step (1) is described is 99.5%.
The purity of the BCDMH that step (2) is described is 98%.
The invention has the beneficial effects as follows: the compound method that a kind of city domestic sewage disinfectant is provided, the method device therefor is few, production technology simple, it is little to invest, the production of product is all harmless with use, can fully meet the demand of city domestic sewage coagulation sterilization, product has the various bacteria of killing, virus, ammonia nitrogen in removal waste water and the ability of phosphorus, and flocculating effect is good.
