Description
Technical field
The present invention relates to two fraction salt treatment process of a kind of high saliferous industrial wastewater, belong to the water treatment field in environmental conservation.
Background technology
All kinds of industrial and mining establishment with Chemical Industry as representative, water consumption is huge, and the wastewater flow rate of generation is also big, and water quality is complicated, and pollutant levels are high, and salinity is high.The waste water of these enterprises discharge can be collectively referred to as high saliferous industrial wastewater.At present, after high saliferous industrial wastewater is processed by pretreatment, biochemical treatment and recycle-water, can meet reuse requirement, but owing to the Water Sproading rate of recycle-water system is the highest by only 80%, cause the high strong brine remaining 20% can arrange nowhere, therefore seek the high saliferous technology for treating industrial waste water that Water Sproading rate is higher, technology stability is higher, operating cost is lower, it is achieved and waste water zero emission, have become as the self-demand of the industry developments such as Coal Chemical Industry and external requirement.
So-called zero-emission, refer to ad infinitum to reduce pollutant and can source emission until the activity of zero.Its content is, first has to the pollutant controlling to have no alternative but liquid, gaseous state and the solid-state of generation in production process, is reduced to zero；Next to that the energy recycling in those emissions, resource are reclaimed, finally realize the no pollution to environment.
Wastewater zero discharge referred to as zero liquid discharge (ZLD) abroad, refers to that any type of waste water does not discharge to waters, earth's surface in enterprise.The industrial water system that zero-emission is construed in the GB/T 21534-2008 " water for industrial use water saving term " of quality supervision and test quarantine general bureau of China in 2008 promulgation enterprise or main unit reaches without arranging outside industrial wastewater.Even if in short, the form that industrial wastewater is condensed into solid or concentrated solution by zero-emission is acted upon rather than to be discharged to natural water outside the form of waste water again.
" zero-emission " of high saliferous industrial wastewater, fully recovering, the most not waste discharge after treatment such as the waste water that will produce in production process, sewage, peace and quiet lower water；Meanwhile, carry out the salinity in waste water concentrating, separate and recycle after crystallization treatment, reduce the discharge of solid waste to greatest extent.
At present, domestic almost all of so-called waste water zero emission project each means the zero-emission of liquid, all kinds of inorganic salts in waste water, Organic substance are then with the form evaporative crystallization of mixing carnallite out, and this part mixed salt is owing to adulterating mutually and containing Organic substance, not only can not recycle, to carry out processing as hazardous waste on the contrary and dispose；Process, consequently, it is possible on the one hand considerably increase, the cost disposed, on the other hand too increase the risk of the secondary pollution to surrounding.
Generally characterize the salinity of waste water with total dissolved solid (TDS), the total dissolved solid in high saliferous industrial wastewater mainly includes soluble inorganic salt ion and dissolved organic matter；Wherein, after pH regulator, softening pretreatment and advanced oxidation process, each component proportion is: sodium chloride 30%-45%, sodium sulfate 50%-65%, sodium nitrate 5-10%, Organic substance 1-3%, other 1-3%.As can be seen here, though high saliferous industrial wastewater complicated component, sodium chloride, sodium sulfate and sodium nitrate proportion exceed the 95% of total dissolved solid.Therefore, how these three inorganic salt is efficiently separated, crystallizes and purifies so that it is meet industrial reuse standard, be the key point of high saliferous industrial wastewater realization " zero-emission " truly.
Restriction due to many factors such as the most domestic technical merit, equipment investment, operating cost and operation stabilities, make high saliferous industrial wastewater can not be effectively separated crystallization, the sodium chloride of output, sodium sulfate and sodium nitrate are extremely difficult to industrial reuse standard, and investment and operating cost remain high, seriously constrain the development of high saliferous industrial wastewater " zero-emission " technology.
