What are the processes for handling trimethylolpropane?

Trimethylolpropane is important in chemical products, and it is also widely used in many fields, such as: resins, coatings, plastics, textiles and so on. However, trimethylolpropane production process will bring pollution, such as: exhaust gas pollution and wastewater pollution, this kind of industrial wastewater can not be directly discharged into the water body, need to be purified and discharged.

1. Hydrolysis acidification method

Hydrolytic acidification is mainly used in wastewater treatment process with high organic matter concentration and high SS. During this period, large molecule pollutants are converted into small molecule pollutants in TMP wastewater treatment, which improves the biochemical capacity of TMP wastewater treatment and lays down good reaction conditions for the subsequent treatment process.

2.Contact oxidation method

Contact oxidation method is a biological treatment method for wastewater derived from the biofilm method, i.e., filling a certain number of fillers in the biological contact oxidation tank, using the biofilm and fully supplied oxygen to oxidise and decompose the organic matter in the trimethylolpropane wastewater to achieve the purpose of purification.

3. pH adjustment tank

As the indicators of trimethylolpropane wastewater will fluctuate greatly with the drainage time, the adjustment pool is set up to regulate the quality, quantity and pH value of the wastewater, and also to prevent the treatment equipment and pipelines from being affected by changes in the peak flow or concentration of the wastewater. In order to protect the subsequent equipment, the adjustment pool is equipped with a homemade coarse grating to remove some of the impurities.

4. Coagulation and precipitation method

Under the action of coagulant, the colloid and fine suspended matter in the wastewater is coagulated into flocculant, and then separated and removed as a water treatment method. The basic principle of the coagulation method is to put the coagulant into the trimethylolpropane wastewater. As the coagulant is an electrolyte, it forms colloids in the trimethylolpropane wastewater, electrically neutralising the colloidal material in the trimethylolpropane wastewater and forming flocs that settle.
