Abstract
The present invention discloses a kind of processing method of the abraum salt in cyclopropanecarboxylic acid wastewater treatment, prepare the abraum salt that cyclopropanecarboxylic acid wastewater treatment is produced, abraum salt is placed in Muffle furnace and burns to obtain salt, incineration temperature is 500 DEG C, the burning time is 20min 40min, and fire door is opened at regular intervals and is passed through air.The abraum salt that the present invention produces cyclopropanecarboxylic acid wastewater treatment, which is placed in incinerator, carries out high temperature incineration, control the parameters such as incineration temperature, abraum salt residence time and excess air coefficient, the organic compound in abraum salt is set to decompose oxidation at high temperature, salt after burning is subjected to dissolution filter and crystallization, the crystallization of acquisition can carry out the recycling of resource as by-product Nacl, it can realize and reuse, economize on resources, realize the comprehensive cyclic utilization of resource.
Description
Technical field
The invention belongs to field of waste water treatment, it is more particularly in a kind of cyclopropanecarboxylic acid wastewater treatment at the burning of abraum salt
Reason.
Background technology
The current processing method for abraum salt is using most by desalinization of soil by flooding or leaching method and landfill method.In the desalinization of soil by flooding or leaching method desalinization of soil by flooding or leaching water consumption compared with
Greatly, washings are also easy to produce secondary pollution, reprocess it is costly, and organic impurities in abraum salt be difficult to it is cleared.Landfill method wastes money
Source, and the soil of large area is occupied, cause more serious environmental pollution.
The content of the invention
At a kind of burning of abraum salt in cyclopropanecarboxylic acid wastewater treatment that can remove organic impurities
Reason method.
According to an aspect of the invention, there is provided a kind of processing method of the abraum salt in cyclopropanecarboxylic acid wastewater treatment, accurate
The abraum salt that standby cyclopropanecarboxylic acid wastewater treatment is produced, abraum salt is placed in Muffle furnace and burns to obtain salt, and incineration temperature is 500 DEG C, is burned
Time is 20min-40min, and fire door is opened at regular intervals and is passed through air.
In some embodiments, open fire door every 5min and be passed through air.
In some embodiments, after by the COD of the spent brine solution before detection process respectively and processing
The COD of saline solution come judge whether need continue burn.
In some embodiments, the concentration of the spent brine solution and the concentration of saline solution are identical.
In some embodiments, the concentration of the spent brine solution is 20%, and the concentration of the saline solution is 20%.
Its advantage is：The abraum salt that the present invention produces cyclopropanecarboxylic acid wastewater treatment is placed in progress high temperature in incinerator and burnt
Burn, the organic compound in abraum salt is decomposed oxidation at high temperature, simple to operate and effect is preferable, COD clearance compared with
It is high；The incineration temperature of the present invention is 500 DEG C, it is ensured that the organic matter in abraum salt is fully oxidized decomposition, again will not be because of temperature
It is too high, cause the increase of power consumption；Salt after burning is subjected to dissolution filter and crystallization, the crystallization of acquisition can be used as by-product industry
Salt carries out the recycling of resource, can realize and reuse, economize on resources, realize the comprehensive cyclic utilization of resource.
Embodiment
The present invention is with COD (COD：Mg/L) as Con trolling index, the treatment effect for determining the present invention.
Embodiment 1
The abraum salt that cyclopropanecarboxylic acid wastewater treatment is produced is configured to 20% saline solution, and measure COD is 2600mg/L, will be useless
Salt, which is placed in Muffle furnace, carries out high temperature incineration, and temperature setting is 500 DEG C, and set of time was 20 minutes, every 5 minutes opening fire doors
Air is passed through, after 20 minutes, salt is taken out, 20% saline solution, saline solution gray is configured to, measure COD is
274.6mg/L, COD clearance are 89.4%, after saline solution is filtered, solution clarification, determine now COD and are
131.8mg/L, clearance is 94.9%.
Embodiment 2
The abraum salt that ring and formic acid wastewater processing are produced is configured to 20% saline solution, and measure COD is 2600mg/L, will be useless
Salt, which is placed in Muffle furnace, carries out high temperature incineration, and temperature setting is 500 DEG C, and set of time was 40mi n, every 5 minutes opening fire doors
Air is passed through, after 40 minutes, salt is taken out, 20% saline solution, saline solution gray is configured to, measure COD is
225.4mg/L, COD clearance are 91.3%, after saline solution is filtered, solution clarification, determine now COD and are
113.2mg/L, clearance is 95.6%.
Above-described is only some embodiments of the present invention.For one of ordinary skill in the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.
