(3) adding citric acid, plant fiber, microbial inoculum and organic acid to the mixer and stirring, stirring for 40-50min, the stirring speed is 900-1000r/min, adding coagulation agent, propylene carbonate and 3-butanedi Alcohol, stir for 20-30min, add defoamer, solvent and polychloride salt after fully mixing, stir at high speed for 10-15min, stirring speed is 500-550r/min, and finally add an appropriate amount of synergistic additives to the appropriate viscosity , filtered to obtain component B for use;

(4) The PVC foaming regulator LP-40, 3-methylphenol and antioxidant are added to the mixer for stirring, the stirring time is 30-40min, the stirring speed is 300-350r/min, and the wood fiber powder is added while stirring , carbon fiber powder, water glass and flame retardant continue to stir for 30-35min, stirring speed is 200-250r/min, finally add leveling agent, stabilizer and auxiliary materials and stir to appropriate viscosity, filter to obtain C component.

(5) Put the A component, the B component and the C component obtained in the preceding steps into the mixer and stir, keep the temperature at 50-60 ℃, and the stirring speed is 200-250r/min until the stirring is uniform and the environmental protection can be obtained Non-toxic sewage treatment agent.
