Treatment methods for high-concentration organic wastewater
Thread Content
What methods are people using to treat high-concentration organic wastewater? I currently have organic wastewater with a COD of 200,000 that doesn’t require much treatment; I’d appreciate some suggestions from everyone Thank you
The scope of organic wastewater as defined by the original poster is too broad. If you really want help, I suggest specifying the type, composition, and properties of the wastewater – the more specific, the better. It’s impossible to give any advice based on just this information. However, such high COD levels can be treated by incineration.
It can be incinerated, but it depends on the composition of your wastewater. This aspect is closely related to the exhaust gas treatment system, and it is also the most expensive part. Also, it depends on whether the waste liquid is viscous; if it is too viscous, the liquid needs to be preheated, and higher requirements are placed on the nebulizer as well.
A COD level of 200,000 represents a high concentration, and wastewater incineration could be considered as a treatment method. Additionally, it is advisable to consider evaporation concentration of the wastewater; if the condensed water resulting from this process can be reused in the system as process water, that would be ideal. This approach increases the calorific value of the concentrated wastewater. It is best for wastewater incinerators to be equipped with waste heat boilers to recover steam, thereby making full use of the heat from the high-temperature flue gases generated during incineration and reducing the costs associated with fuel consumption.
It is somewhat hasty to determine the treatment method based solely on the COD value, without considering other water quality indicators or water volume. LZ might as well clarify the water quality indicators, as well as specify what type of wastewater it is and how much volume there is; this will facilitate more targeted discussions. There are many methods for treating high-concentration organic wastewater; biochemical methods can be used, as can physicochemical methods, and incineration is also a viable option. The choice of method or process requires comprehensive consideration to determine.
I’m not sure whether the organic wastewater you’re referring to contains inorganic salts. If salts are present, direct incineration might present some issues; it would be best to provide information on its composition
The COD of pure alcohol is also less than 200w; 20w is already quite high. It is better to burn it, especially when the other components are unknown. I also have a type of wastewater here; its COD concentration is 20,000, ammonia nitrogen levels are 1,000, and SS levels are 1,000. It is a product of the high-temperature hydrolysis of some biological protein. I would appreciate it if you could offer some suggestions as well.
The high-temperature hydrolysis products of proteins consist of many amino acids, which are rich in nutrients. Are there any other ingredients? If it contains no harmful substances, it makes a good fertilizer in solid form.
The administrator should inform the poster to pay attention to professionalism, as wastewater treatment is a technique that requires customization and specificity. Different wastewater types, different regions, different target values (treatment objectives), and different conditions of the project owners all result in different technical solutions. Attention should be paid to similar posts in the future
The COD of the wastewater generated in glutamate production is between 30,000 and 50,000. The treatment process employed is multi-effect evaporation concentration. The concentrated condensate water is sent to the AAO activated sludge treatment tank, while the concentrated product is used in a spray granulation process to produce organic-inorganic compound fertilizers. The technology is mature, offering excellent economic benefits.
