Effects of irrigation and fertilization treatments on transfer and utilization of water and nitrogen in maize root zone;

Nano TiO2/attapulgite have been prepared for photocatalyst treatment NH3-N wastewater.

Based on the experiment of dealing with middle-low concentrated NH3-N wastewater by blow-off method,the result shows that with the test facilities.

Research process on the denitrogenation of highly concentrated ammonium-nitrogen wastewater;

Present situation and development of the treatment of highly concentrated ammonium-nitrogen wastewater;

Treatment of metal-ammonia complex ion-containing high concentration ammonia nitrogen wastewater;

Technology Study and Exploration of Industrial Application on Treating the High Strength Ammonia Nitrogen Wastewater of Coke Plant by Chemical Precipitation Method;

Study on immobilized microorganism technology to treat wastewater containing ammonia nitrogen;

Experimental investigation of processing conditions for treatment wastewater containing ammonia nitrogen with ultrasonic stripping;

The technical conditions of disposal of wastewater containing ammonia nitrogen are studied by the chemical depositing method.

With a simulated high-strength ammonia wastewater,the influence factors of the ammonia-nitrogen removal effect of MAP reactor are investigated.

Magnesium ammonium phosphate (MAP) precipitation method,extensively applied in treating ammonia wastewater of iron and steelmaking, oil refining, fertilizer, chemical industry, ferroalloy glass,fabricate, meat process, feed production and so on, has been developedrapidly.

With the development of industry and agriculture, the discharge of ammoniaincreased greatly, ammonia wastewater became one of the main pollutants that woulddo harm to humans, animals and break nature balance.
