High salt wastewater treatment
High salt wastewater wastewater refers to the total salt mass fraction of at least 1%. It mainly comes from chemical plants and oil and gas collection and processing. The wastewater contains a variety ofsubstances (including salt, oil, organic heavy metals and radioactive substances). The way of produce waste water containing salt widely, content also increased year by year, crucial influence tothe removal of organic pollutants in wastewater contaning sait on the environment caused by the.
The main treatment method of high concentration wastewater with reverse osmosis, ion exchange and distillation, dilution, the processing cost is relatively high, at present, our company is the high salinity organic wastewater biological treatment technology research and development, high saltconcentration in the wastewater has inhibitory effect on biological treatment, the needle on the use of sludge on the adaptability of high salt concentration screening and acclimat of microorganisms.and obtain the halophilic bacteria can withstand higher salinity the biological. treatment of organic wastewater with high content of salt into reality The whole technological process to salt organic wastewater biological treatment technology for wastewater containing high: first through adjusting pool, pretreat and after materialized (pH value adjustment,coagulation, precipitation,electrolysis, micro electrolysis method is usually used and then adding the pre cultured)good halophilic bacteria for biological treatment. Halophilic bacteria, cheap, wide source can utilize many organic compounds (including refractory and toxic substances) as carbon source, therefore, the use of halophilic bacteria in treatment of high salinity organic wastewater has the broad application prospect.

Multi effect evaporation
Multi effect evaporation is to get heated Brine Evaporation in a plurality of series connectedevaporator, steam evaporator evaporation from a previous as the heat source of a evaporator, andcondensed into fresh water.The low-temperature multi effect distillation method is one of the most energy-efficient law Low temperature multi effect distillation technology because of such factors. developing rapidly in recent years,expanding the size of the device,low-cost,the main treng of development in order to improve the unit water ability using cheap materials to reduce project cost, increasing the operating temperature, improve the heat transfer efficiency.
