Abstract

The invention provides a multi-group chelating type magnetic mycelium water purifying agent recycling treatment process and treatment system. The process includes three steps of pretreatment, co-sedimentation and activation, separation and recycling: firstly, the pH value of wastewater is adjusted to 8-9 , adding a multi-group chelating magnetic mycelial water purifying agent to stir the reaction; separating the reacted liquid under the synergistic driving of a magnetic field and gravitational field to obtain first-level purified water and water purifying agent residue; activation and separation of the water purifying agent residue are obtained respectively Recyclable heavy metal waste acid, effective water purifier and non-magnetic failure state water purifier that can be directly returned to the system. The circulating treatment system device includes a heavy metal wastewater reaction tank, a magnetic separator, a further processor, a rinsing separator, a water purification agent storage tank, an activator storage tank and connecting equipment. The multi-group chelating magnetic mycelial water purifying agent circulation treatment process and system provided by the invention have the characteristics of simple structure, fast precipitation and separation, plug-and-play portable, etc., and can realize rapid emergency treatment of water pollution sites.

Description

technical field [0001] With the rapid development of economy, heavy metal pollutants and organic pollutants in wastewater have become one of the most serious environmental problems in China and even in the world. This kind of wastewater has high toxicity, biodegradability and accompanying volatilization characteristics, which will not only affect the ecological environment, but also cause major harm to human health through the food chain. At present, among the water treatment methods, adsorption method is considered as an efficient and economical method for the treatment of heavy metal organic wastewater. The adsorption method is easy to operate, low in cost, low in pollution and recyclable, especially in the treatment of low-concentration wastewater, which is favored by researchers. Currently, the most widely used heavy metal ion adsorbent is activated carbon. Because of its high specific surface area and reactivity, activated carbon can effectively remove heavy metal ions ...
