Description
Technical field
The present invention relates to a kind of thimerosal, and in particular to the 1,3-dibromo-5,5-dimedisinfectantn disinfectantn in a kind of production process for recycled writing paper
And preparation method thereof.
Background technology
Substantial amounts of waste water can be produced in papermaking enterprise production technology, how to realize utilizing the treatment Posterior circle of waste water,
Realize that energy-saving and emission-reduction are the problems that papermaking enterprise is studied always.But due to being rich in microorganism and microbial fermentation in papermaking systems
Necessary nutriment, and papermaking systems closed operation, cause microorganism particularly to produce the anaerobic bacteria urgency of stink
Increase severely plus, so as to cause the problems such as smelly water quality of cycling use of water, blackening, and the anaerobic fermentation of anaerobic bacteria can cause paper pulp
Fiber be destroyed, so as to produce the phenomenons such as paper pulp wall built-up, the disconnected paper of rotten slurry.General papermaking enterprise is using chlorinated product in paper pulp
Microorganism is controlled, but chlorinated product has following defect in itself：First, the smell of chlorinated product is big, and excitant is strong, easily right
Operating personnel damage；Second, paper pulp is an extremely complex system, wherein having COD and ammonia nitrogen very high, these materials
Chlorinated product will be rapidly consumed, prevents chlorinated product from playing the effect of itself sterilizing, cause consumption big, and chlorinated product
Produced chloride also has very big toxic and side effect to environment, there is a problem of to secondary pollution.
1,3-dibromo-5,5-dimedisinfectantn disinfectantn is relatively low because of its effective bacteriocidal concentration, and sterilization speed is fast, and under field conditions (factors) can by light,
Oxygen, microorganism etc. resolve into nitrogen and carbon dioxide within a short period of time, will not will not also be produced poisonous because of residual contamination environment
Material, thus be used to be carried out disinfection instead of chlorinated product.But solubility of the C5H6Br2N2O2 in water is very low, dissolution velocity is slow,
Stability after being dissolved in water is poor, limits the use of DBDMH disinfecting agent；And due in recycled writing paper production process
