AI Technical Summary

Problems solved by technology

However, the amount of urban wastewater produced is huge, and the consumption of sewage treatment agents for treatment is also very large. The sewage treatment agents in the prior art are disposable products, and the desorption process cannot be used to recycle the treatment agent, and the cost of sewage treatment is high. Therefore, a kind of sewage treatment agent was developed. High-efficiency adsorption sewage treatment agent to improve the above problems

Abstract

The invention discloses an efficient adsorption type sewage treatment agent and a preparation method thereof. The efficient adsorption type sewage treatment agent is prepared from straw-based magnetic porous biochar, nano silicon dioxide, modified coconut shell charcoal, porous basalt, modified zeolite, plant fibers, a porous metal material and a flocculating agent. The prepared efficient adsorption type sewage treatment agent is high in adsorption capacity, ammonia nitrogen and other substances contained in water can be removed, the treated wastewater becomes recycled water which can be used for irrigation, flushing and the like, the water utilization rate is greatly increased, the modified coconut shell charcoal, the porous basalt and the modified zeolite are added to enhance the adsorption capacity, the flocculating agent is added to greatly enhance the flocculation capacity and the precipitation capacity, and the plant fibers are soaked in sodium oxalate to make condensed organic matters not prone to dispersing under the conditions of high sewage flow rate and high temperature.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an efficient adsorption sewage treatment agent and a preparation method thereof. Background technique [0002] Cities consume a lot of water every day, and my country is a country with insufficient water resources per capita. Therefore, it is necessary to treat wastewater so that it can be reused, that is, wastewater is converted into recycled water, also called reclaimed water. Reclaimed water refers to wastewater or Rainwater is water that can be used beneficially after being properly treated to meet certain water quality indicators and meet certain use requirements. Compared with seawater desalination and cross-basin water transfer, reclaimed water has obvious advantages. From an economic point of view, the preparation cost of reclaimed water is the lowest. From an environmental point of view, sewage recycling helps to improve the ecological environment and realize the...
