Filter industrial wastewater treatment facilities design ideas simply apply in urban sewage treatment works will bring a lot of unexpected problems. Urban sewage treatment plants is characterized by larg e-scale, large area of facility size, multi-unit treatment facilities usually reinforced concrete structure accordingly require the whole process constitute a simple monomer facility form should simplify and minimize pipeline interludes and complex structure, in order to reduce the total amount of the maintenance and management of the facilities and equipment of the whole plant. Better accounted for only three filter efficiency (the rate of operation of pollution control facilities, equipment utilization, pollutant removal) of the total number of operating facilities 35.7% pollutant removal efficiency of only 50% of the design capacity, the overall The effective investment accounted for only dealt with all the facilities for a total investment of 31.3%, less than 1/3 of the equipment to play a role.
With the development of society and the enhancement of people s environmental awareness, water pollution control experienced by a single pollutant sources, the concent ration of pollutants discharge standards to regional integrated pollution prevention and control, based on the capacity of the environment pollutant emission control two stage. In the past decades, China s pollution prevention and control work has been to get rid of not point sources, discharge, and three at the same time and the polluter who governance policies, actual results are not satisfactory.belt filter press manufacturers
Y-strainer According to the State Environmental Protection Administration (SEPA) of 5556 sets of industrial wastewater treatment facilities survey results show that, we can see that the original wastewater treatment system planning, design, ideological principle, there are many problems, is no longer to adapt to the current economic development in China and environmental protection requirements. Industrial wastewater treatment is technically similar to the urban sewage treatment, precisely because of the large size of the urban sewage treatment facilities, invest more, it s rugged and simple, long service life, good economies of scale, lower unit processing costs run effect prominent role to play in environmental governance, stability pipeline filter has been determined to engage in urban sewage treatment works, according to the characteristics of urban sewage treatment works, learn from other people s experience with the technology, and careful selection of process options being considered, namely: Overall simpler process constitutes the monomer facility constitutes To simplify, ease of maintenance, ease of operation, energy consumption as low as possible, covering as much as possible to stabilize the province, run effect.
The filter characteristics of industrial wastewater treatment: the targeted technological change. The main technical oil separation, flotation, coagulation, sedimentation, gravity filtration and membrane filt ration, activated carbon adsorption, ozonation, ion exchange, electrolysis, electrodialysis, reverse osmosis and other proprietary technology to separate oil, color reduce industrial waste water, heavy metals, toxic and hazardous substances in industrial wastewater treatment is often used in hydrolysis acidification contact oxidation, surface aeration, pure oxygen aeration, anaerobic and aerobic activated sludge biochemical techniques. Generally small-scale industrial wastewater treatment facilities, technical, flexible combination of technology, the structure is usually steel, even if the internal pipeline interspersed more, the operation and maintenance is not too difficult.
