Circulating cooling water discharge collar solutions

First, circulating cooling water is the exchange of heat through the heat exchanger or direct contact heat exchange medium heat mode and after cooling tower cold water, recycling to save water resources. Under normal circumstances, the recycled water is neutral and alkaline, pH value control between 7-9.5; circulating cooling water in acidic or alkaline (pH greater than 10.0) in the case of direct contact with the media, general less. Second, to improve the cooling water concentration ratio of benefits to improve the cooling water of concentration, can reduce the amount of make-up water, conservation of water resources; increase of concentration of cooling water, sewage water can be reduced, thereby reducing environmental pollution and wastewater treatment capacity ; increase of concentration of cooling water, water treatment agent can save consumption, thereby reducing the cost of cooling water. Third, the use of agents to improve the concentration ratio of the disadvantages of excessive use of water cooling agent to improve the cooling water of concentration, cause cooling water hardness, alkalinity rises too high, the water tends to increase a lot of fouling; so that knot dirt becomes too difficult to control; circulating cooling water will cause corrosive ions (such as Cl and SO4) contents and corrosive substances (such as H2S, SO2 and NH3) increases, corrosive water increased, so that corrosion the difficulty of controlling the increase; too much concentration ratio will increase the medicine (such as polyphosphate) in the cooling water system, the residence time of growth and hydrolysis, therefore, the use of chemical treatment of cooling water of concentration is not as high as possible . To ensure that the effect of cooling water treatment, cooling water must control the concentration ratio, in addition, the use of chemicals to improve concentration ratio also increases the consumption of water treatment agent, thereby increasing the cost of the cooling water at the inside. Usually thermoelectric system can control 2 to 5 times, chemical, oil refining 2 to 4 times. Fourth, macro and energy circulating cooling water discharge solutions lead the world countries to many industrial wastewater treatment research, which covers an area of ??small electrochemical device, flexible operation, a small amount of sewage, not only can handle inorganic contaminants that can also handle organic pollutants, and even some unable biodegradation of toxic organic compounds and some heavy metal wastewater treatment are available for this method; reduce plus wind, nuclear power and other new technologies to develop and promote the use of energy costs to bring such The electrochemical process has a greater advantage in terms of treating wastewater. Electrochemical scale filter system I plant with domestic water quality characteristics, after years of research scale processing equipment, is another innovative product in the field of water treatment. The device is an investment, a lifetime, as China's low-carbon life advocates, such technological achievements will completely replace the traditional treatment of chemical pollution in a short time.
