高鹽廢水是指總含鹽質量分數至少1%的廢水.其主要來自化工廠及石油和天然氣的采集加工等.這種廢水含有多種物質(包括鹽、油、有機重金屬和放射性物質)。含鹽廢水的產生途徑廣泛,水量也逐年增加,去除含鹽污水中的有機污染物對環境造成的影響至關重要。
高濃度含鹽廢水的主要處理方法有反滲透、離子交換、蒸餾、稀釋等,處理成本比較高,目前我公司正在對高含鹽有機廢水生物處理技術進行研發,廢水中較高鹽濃度對生物處理有抑制作用,針對利用污泥對高鹽濃度的適應性,對微生物進行篩選和馴化,獲得的嗜鹽菌可承受較高鹽度,使生物處理高含鹽有機廢水成為現實。高含鹽有機廢水生物處理技術采取的整體工藝流程為:廢水首先經過調節池,然后經過物化的預處理(通常采用調節pH值、混凝、沉淀、電解、微電解等方法),而后加入預先培養好的嗜鹽菌進行生物處理。嗜鹽菌廉價,來源廣,可以利用許多有機物(包括難降解和有毒物質)作為碳源,因此,利用嗜鹽細菌處理高含鹽量有機廢水有廣闊的應用前景。

多效蒸發(MED)
多效蒸發是讓加熱后的鹽水在多個串聯的蒸發器中蒸發,前一個蒸發器蒸發出來的蒸汽作為下一蒸發器的熱源,并冷凝成為淡水。其中低溫多效蒸餾是蒸餾法中最節能的方法之一。低溫多效蒸餾技術由于節能的因素,近年發展迅速,裝置的規模日益擴大,成本日益降低,主要發展趨勢為提高裝置單機造水能力,采用廉價材料降低工程造價,提高操作溫度,提高傳熱效率等。

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.
