Abstract

The invention provides an integrated device for preprocessing of printing ink wastewater. The integrated device comprises a first lift pump, a first diaphragm pump, a first reactor, an intermediate groove, a second lift pump, an electrolytic bath, a second reactor, a second diaphragm pump, an automatic dosing system and an automatic control system. The integrated device for preprocessing of the printing ink wastewater and a technological process of the integrated device have the following advantages: facilities and equipment for preprocessing of the printing ink wastewater are integrated into a modularized device to the maximum extent, so that input cost and supporting civil investment of treating facilities are greatly reduced; the automatic control system is arranged, so that automation degree is high, and the whole process for processing the printing ink wastewater can be in one-key operation; quality of effluent after treatment of the printing ink wastewater is completed is stable, suspended matters and color scale reach grade 1 emission standard under national environmental requirements, and the effluent can be totally reused for water supply for production.

Description

technical field [0001] The invention relates to equipment for wastewater pretreatment engineering facilities, in particular to an ink wastewater pretreatment integrated device and its process. Background technique [0002] The difficulty of wastewater treatment in the printing industry lies in the fact that wastewater contains high concentrations of refractory organic matter. Generally, the daily emission of a single production enterprise is very small (in a few liters, dozens of liters, hundreds of liters, medium and large enterprises can only reach 10m 3 -80m 3 daily discharge), due to the small amount of wastewater discharged, the treatment process is complicated, the treatment process is difficult, and the project cost of the traditional treatment process is high, and the general small and medium-sized printing enterprises cannot afford the investment cost of environmental protection. As a result, a large number of small and medium-sized printing companies have not bee...
