In the study, the process neutralization acid waster water from soapstock processing by high calcareous phosphorite of Central Kyzylkum at temperature 60 ºC by drainless technology was investigated. As a result, digested forms of P2O5 by citric acid and Trilon B in final products were ranged 30.28-50.43 and 25.58-39.93%, respectively. Those types of products can be used under autumn chill.

A series of tailings and sediments samples were collected from Linahuashan tungsten mining area. Particle composition, arsenic concentrations and arsenic speciation distribution in the tailings and sediments were investigated. The proportion of large particle (> 170 μm) in the tailings varied from 37% to 50%. Arsenic (As) concentrations in the tailings ranged from1889 mg·kg-1to 3135 mg·kg-1. The sediments upstream were similar to those in the tailings in particle composition, As concentrations and speciation distribution. The sediments in the middle or lower reaches of the stream contained finer texture and lower As concentrations than the tailings. Compared to the tailings, Acid waste water with a lot of tailings particle enter the stream. Most of larger particle in acid waste water settled upstream, and smaller particle and soluble As precipitated in the middle or lower reaches of the stream. Smaller particle fraction contained higher percentages of Fe-As, Ca-As and Al-As, while larger particle fraction contained higher percentages of FeOc-As and Res-As.

Application of whey soy proteins to wastewater processing and beverages were investigated under different conditions.Decoloration and deflavoring eficiency were determined using activated carbon under different temperature,and desalination with ion exchange resins and trypsin inhibitor activity(TIA)was investigated when tested in Sucrose addition and Citric acid addition.The experimental results of whey soy proteins wastewater pretreatment showed that the best conditions of decoloration de-flavoring were:10% of activated carbon,50°C of temperature,adsorption time for 40 min,and the best condition of desalination was 4.28mL/min of flux using ion exchanging resin.
