Many Internet users in the advice about the problem of textile wastewater treatment equipment today small make up this site on the Internet to find the second article on textile wastewater treatment equipment related information, please follow look small make up for textile printing and dyeing wastewater treatment and reuse of generally includes three processes: the first step is to use common physicochemical and biochemical treatment process meet the discharging standard wastewater treatment, the second step is to meet the requirements of discharge wastewater deep treatment, 2)
Biochemical treatment: use the carrier after domestication, hanging film composite membrane mud flow bed reactor (
The CBR reaction pool)
In primary air floatation processed wastewater aerobic organic matter decomposition (3)
Post-processing: clear liquid water on the tank into the secondary air flotation
pool, by adjusting the reflux ratio of secondary air flotation pool and dissolved air pressure, further remove the impurities in the waste water and suspended particulate matter and to reduce the effluent SS, then introduces wastewater pool ozone oxidation, through the strong oxidizing ozone, will be difficult to degradation of organic matter in the process for biological treatment of further degradation, as well as the use of ozone bleaching performance, guarantee the shade of the water, finally introduces ozone pool textile effluent of sewage treatment equipment
recycling pool, realize the waste water reuse 1)
This process is the existing mature wastewater biological treatment and physical and chemical treatment process, through the optimization of the parameters and biological carrier composite membrane reactor through the mud microbial screening and domestication, able to handle high pollutants concentration, high colority textile printing and dyeing wastewater, water quality is not stable, low operating cost, good treatment effect, stable operation, the advantages of simple operation, 2)
This technology can effectively solve the textile printing and dyeing enterprise school wastewater treatment equipment industry wastewater reuse treatment, water reuse water quality meets the demand of printing and dyeing enterprises of water, can solve the contradiction between the textile printing and dyeing enterprise development and pollution emissions, achieve the energy conservation and emissions reduction targets of the enterprise, reduce the operating cost of the enterprise, improve enterprise's competitive advantage, textile printing and dyeing wastewater treatment process equipment technology process on the basis of quality characteristics of printing and dyeing wastewater treatment project, using A/O process with dominant fungi wastewater treatment technology, process flow is: at the beginning of heavy oil pool -
Adjust the pool -
Hydrolysis acidification -
Biological contact oxidation -

Level discharge standard ii, luoyang water environmental science sewage treatment equipment gas float processing unit function of the original title: luoyang water beautiful air flotation processing unit in environmental science in the sewage treatment equipment beautiful rural area, air flotation sewage treatment equipment, equipment and the introduction of the previous period of aeration device, all is the auxiliary processing unit in luoyang, sewage treatment equipment, but the difference is floating processing unit is not must be equipped with, it is decided according to the actual situation of sewage disposal project, if the oil in the wastewater is not a lot of words can not use of air flotation equipment, part of which reduces investment spending, and reduce overall project cost, below the water environmental protection will give you details of the specific details and air flotation equipment use details only when there are floating in the water under the condition of the particulate matter (
Raw water in succession such as chemical fiber, fine sand, silt or waste water by the organic chemistry or physics are dissolved in water, colloid solution into a suspended solid)
With plenty of the total number of superfine grain bubble caused by adhesion, wrapped clip physical knowledge, such as the proportion of textile wastewater treatment equipment make the particles below the water and separate goal 6, heavy metal exceeds bid ionization, electroplating wastewater of organic chemistry to solve solid-liquid separation process is the luoyang sewage treatment equipment of air flotation processing unit details, to say the air floating device can effectively improve the processing indexes of sewage treatment, to achieve better clean degree of wastewater, but want to choose according to their own requirements, if the discharge of sewage into the municipal pipe network can save the device, in order to save investment to improve the efficiency of other equipment, the limited resources as much as possible to improve the efficiency of the main processing equipment
