② The wastewater may include unreacted raw materials, solvents, and a large number of compounds, which vary from chemical reaction to chemical reaction. In biochemical treatment systems, the concentration of the compounds per unit volume of biomass is too high or toxic, and thus chemical pretreatment of the wastewater is generally required prior to biological treatment.
③ The waste water has complex components, contains substances which are difficult to degrade by microorganisms and even have strong inhibition effect on the microorganisms, such as organic or inorganic salts, intermediate process products, residual solvents, chemical residues, decomposition products and the like which are added in the reaction process, and can inhibit the growth of the microorganisms under the condition of small dosage when the waste water has certain concentration, so that the start-up domestication period of a biochemical system is prolonged, and the anaerobic gas production and biochemical treatment efficiency are reduced.
④ Since wastewater contains a large amount of chemical components, the wastewater has biotoxicity and poor biodegradability.
⑤ The pH value of the wastewater is changed frequently, and the fluctuation range is large; the pH value of the wastewater is acidic or alkaline.
The water quality is shown in Table 1.
