Water reuse equipment in the chemical industry

1、 Equipment Introduction

The water reuse equipment in the chemical industry mainly applies membrane biological treatment technology to the water treatment equipment for the regeneration and utilization of chemical wastewater. The basic characteristics of wastewater in the chemical industry include complex water quality components, multiple by-products, and often solvent based substances or cyclic compounds as reaction materials, which increases the difficulty of wastewater treatment;(The high content of pollutants in wastewater is caused by incomplete reaction of raw materials and the entry of large amounts of solvent media used in raw materials or production into the wastewater system; There are many toxic and harmful substances, and there are many organic pollutants in fine chemical wastewater that are toxic and harmful to microorganisms, such as halogen compounds, nitro compounds, dispersants or surfactants with bactericidal effects, etc; There are many biologically recalcitrant substances,B/CLow ratio, poor biodegradability; High chromaticity of wastewater, etc.

The water reuse equipment in the chemical industry is an integrated fully automatic biofilm reactor, also known asMBRThe biological treatment technology of the equipment can completely replace the traditional reclaimed water treatment process. It can achieve the integration of water inlet and standard effluent, greatly reducing land area and labor. Moreover, the effluent is stable and easy to operate, and can efficiently remove various toxic substances and bacteria from the water. The amount of sludge produced is very small, and the suspended matter in the water is almost zero discharged. It also has disinfection and sterilization effects, directly treating the reclaimed water to meet the standard.

4、 Design Features

1. The system adopts fully automatic control(Manual control can also be used, and automatic backwashing and regeneration programs can be set during system operation;

2. Pipelines are generally usedUPVCtexture of material;

3. Integrated control system and integrated instrument system, etc., facilitate operation and management;

4. The equipment has an automatic prompt function for consumables replacement, and the replacement cycle of consumables depends on changes in water quality and pressure, rather than the usage time of consumables. Considering the differences in water quality in different regions, the design is more scientific;

5. It can effectively perform solid-liquid separation, separating suspended substances, colloidal substances, and microbial communities lost from biological units in wastewater from purified water. The separation process is simple, occupies a small area, has good effluent quality, and generally does not require tertiary treatment for reuse.
6. It can maintain high concentration of biomass in the biological treatment unit, greatly increase the volumetric load, shorten the hydraulic retention time of the treatment unit, and correspondingly reduce the footprint of the bioreactor.
7. Due to its ability to prevent the loss of various microbial communities, it is beneficial for bacteria with slow growth rates(Nitrifying bacteria, etc)The growth of the system enables various metabolic processes to proceed smoothly.
8. Extending the residence time of some macromolecules that are difficult to degrade organic compounds is beneficial for their decomposition.
9. Membrane treatment technology, like other filtration and separation technologies, is prone to clogging as a filtration medium during long-term operation. The amount of water passing through the membrane gradually decreases over time. Effective backwashing and chemical cleaning can slow down the decrease in membrane flux and maintain itMBRThe effective service life of the system.
