Zero emission system and process for organic silicon production wastewater

The invention discloses an organic silicon production wastewater zero discharge system and process, relates to the technical field of treatment of water, wastewater, sewage or sludge, and aims to solve the problems that the existing organic silicon wastewater treatment process is unstable and difficult to reach the standard, and meanwhile, most organic silicon wastewater is discharged into a sewage treatment plant in a park, so that the wastewater treatment cost is reduced. The sewage treatment plants in the park all adopt conventional biochemical treatment and precipitation filtration processes, and almost have no effect on specific pollutants contained in the organic silicon wastewater, so that the actual effect of discharging the organic silicon production wastewater into the sewage treatment plants in the park is equivalent to dilution discharge, and the potential environmental pollution is very serious. The wastewater zero discharge system comprises a pretreatment unit, an evaporation unit, a biochemical
