Contact oxidation (
, coagulation -
The centers for disease control and prevention, water oxidation pool sewage treatment equipment
, water (
On the static settling after)
, COD is 150 mg/L, chromaticity, 200, used a variety of drugs (
Aluminum sulfate and decoloring agent, ferrous sulfate and lime)
, because of the reconstruction project, coagulation dosing for 4 h after water, easy to color, but the cost is too high or cannot make COD colorimetric standard question 4: at the same time treatment station operation is normal, just started out of the water is not good, a tan, but it's good anaerobic effluent, after oxidation ditch is out of the water is not good, at the beginning of the oxidation ditch pond water with mud and water or a blond, don't know what to do, aeration, fujian sewage treatment equipment level bubble with a little green, now is to remove water colority problem five: I early treatment of printing and dyeing wastewater treatment
process in regulating pool is + sink sink + 2 + + hydrolysis contact sand filter, the normal usually yellow or a little pink, sometimes appear blue, green, blue-green, excuse me what reason be cause sometimes aeration biological filter sewage treatment equipment manufacturers of aeration biological filter wastewater treatment, the equivalent of habitat for microbes is added in the aeration tank with sewage treatment equipment of fujian province to fill,
Expected, the air-blowing under packing, is has the characteristics of the activated sludge biological membrane method, this process has the removal of SS, COD, BOD5, nitrification, denitrification and phosphorus removal effect, its biggest characteristic of small medical sewage treatment equipment is integrating biological oxidation and intercept suspended solid, save the subsequent two pond, on the premise of guarantee treatment effect to improve process simplified aeration biological filter principle of wastewater treatment process, biological filter water purification filter material in filter is the principle in the growth of biofilm on the microbial oxidation decomposition, filtration and adsorption intercept effect of biofilm and along the flow direction of classifying predator food chain, and biofilm formed by the internal micro environment and anaerobic denitrification - chengdu water technology co. , LTD
Aeration biological filter sewage treatment equipment supplier three operation management, sewage treatment equipment maintenance (1) when the equipment installation, attention should be paid to adjust fixed and mobile parts (
As a guide in fujian sewage treatment equipment for rail and sliding block)
Clearance, ensure the decontamination rake up and down movement of smooth vibration faults in abnormal sound method to eliminate the original chassis overheating clinic sewage treatment equipment manufacturer for under a certain speed has nothing to do with the rotating speed is proportional to the speed of has nothing to do with the air flow under a certain air of continuous intermittent impeller wear and corrosion
are an important part of the society and they come in handy in any place where there are wastewater solutions in need of wastewater solutions.
