What is high salt wastewater?
High-salt wastewater refers to wastewater with a total salt content of at least 1%. It is mainly from chemical plants and oil and gas collection and processing. This wastewater contains a variety of substances (including salts, oils, organic heavy metals and radioactive materials).
Treatment of high-salt wastewater:
Evaporation method, electrochemical method, ion exchange method, adsorption, membrane separation technology, etc., effectively combine physical, chemical and biological methods.
Sewage treatment equipment:
First, the centrifuge is mainly used to separate the solid particles in the suspension from the liquid.
Second, the sludge dewatering machine can automatically control the operation, continuous production, stepless speed regulation, suitable for a variety of sludge, suitable for sludge in various industries such as water supply and drainage, paper making, casting, leather, textile, chemical, food, etc. Dehydration.
3. The aeration machine directly injects the “microbubbles” into the untreated sewage through the diffused air impeller. Under the joint action of the coagulant and the flocculant, the physical flocculation and chemical flocculation of the suspended solids form a large The suspended floc is floated on the surface of the bubble group to form a dross, which is separated from the water by a scraper.
4. Micro filter machine, drum type screen filter device. The treated wastewater enters the drum in the axial direction and flows out through the screen in a radial radial direction, and the impurities in the water are trapped on the inner surface of the filter on the drum. When the impurities trapped on the filter screen are brought to the upper portion by the drum, the pressure flushing water is backflushed into the slag discharge tank and flows out.
5. Air flotation machine, equipment for removing suspended solids, grease and various gels in various industrial and municipal sewage. The equipment is widely used in the treatment of industrial wastewater and municipal sewage such as refining, chemical, brewing, slaughtering, electroplating, printing and dyeing.
6. Ozone generator, which can decompose organic macromolecules into small molecules, decompose difficult-dissolved substances into soluble substances, convert refractory substances into degradable substances, and decompose harmful substances into harmless substances, thereby achieving sewage purification the role.
