Filled column 14 is mainly used in GAS ABSORPTION, and it adopts close packed structure as depicted, and fabric filter element 25 then adopts Active carbon fiber filter core, is mainly used in the absorption to float, and its effect is mainly reflected on material.
Sewage purification medicine generally has the various inorganic coagulant such as aluminium salt, iron salt, flocculant, is mainly used in sewage sedimentation, flocculation.
Sewage disposal: in the sewage disposal system using the various inorganic coagulant such as aluminium salt, iron salt, flocculant, exceed the disposal ability of depositing reservoir if desired for the water yield processed or floated outward owing to other factors cause flco in water to have little time sedimentation, the PAM that only need to add 0.1-2ppm helps solidifying, can significantly improve effect of settling.And, after process, the COD of water and chromaticity index also can improve significantly.
Sludge condensation: use the inorganic coagulant of 0.3-2ppm can reduce the ratio of mud and water in biochemistry pool and sludge concentration tank, improve the utilization rate of biochemistry pool and sludge concentration tank.Sludge concentration can be brought up to 30--100g/L by 3---10g/L, substantially reduce the mud body weight of the process of next step sludge dewatering, improve device for dehydrating sladge waste and personnel's effective percentage.
Sludge dewatering: model and dosage and mud cake dry be considered as the difference of mud kind and different after dehydration, therefore various different model products need to be carried out test and Selection.
In the present embodiment, described sewage treatment pot 1 top is provided with outlet three, sewage treatment pot 2 18 top is provided with outlet four, bottom is provided with water inlet three, sewage treatment pot 3 16 bottom is provided with water inlet four, water after being disposed is flowed out by the top of sewage treatment pot 3 16, and the dirt in water is deposited in lower floor under gravity, utilize the improved effect treatment effect of gravity.The workflow of the present invention is as shown in Figure 3: after the water in circulating water pool 1 enters treating column via water pipe 1 under the effect of suction pump 3, enter jet air float machine jet air float, silt and greasy dirt that mud filtering device 9 is removed in water is entered under gravity after completing jet air float, silt and greasy dirt filter after water enter metal filtering device and carry out the adsorption treatment of metal, gravity is utilized by whole treating column dexterously, save while saving the energy and use space, recirculated water is after having processed by treating column, enter sewage treatment pot unit and carry out further biochemical reaction and absorption, after filtering, thus completing precipitation and the removing of particulate matter in water, whole procedure layout is reasonable, impurity-eliminating effect is good, water after having processed enters clear water reserviors 15 and stores, etc. to be utilized.
Above-described is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention.
