main technical contents

1,fundamental

Pool material made with high and new technology, make the sewage treatment equipment of whole set to advanced technology, reasonable configuration, excellent performance, good corrosion resistance, convenient maintenance, beautiful appearance. Pool material according to different reactor in the form of anticorrosive prefabricated steel plate, special sealing material leak proof, this kind of prefabricated steel plate form a protective layer can not only prevent the corrosion of tank, and has the function of strong acid, strong alkali resistance. Short build period; Corrosion resistance is strong; The sewage plant expansion to less investment and put into production soon

2, Technological process:

Regulating pool ­ - gas fugitive dust fall pool - YanYangChi - biological aerobic pool - the second pond - filter - water recycling pool

Process description:

The design of the equipment is mainly for domestic sewage and industrial organic wastewater treatment. The main processing method is to use the relatively mature contact oxidation pool biochemical treatment technology. Water quality design parameters according to the sewage water is 250 mg/L BOD5, effluent BOD5 calculation for 20 mg/L. At the beginning of a total of seven parts: pond; Anaerobic pool; Contact oxidation pool; The second pond; Pool disinfection, disinfection device; The sludge pool; The wind of computer room.

(1) the early pond: early pond for vertical flow sedimentation tank, sewage in the rising velocity of settling basin is 0.3 ~ 0.4 mm/SEC, settle sludge to sludge pools. SFW - 5 pond, early and the following equipment is not set.

(2) anaerobic pool, anoxic pool Settings for nitrogen treatment, pool YDT stereo elastic filler is installed inside, as the carrier of denitrifying bacteria, nitrifying back into nitrate and ammonia and acid in liquid state under the action of denitrifying bacteria, oxygen reduction of nitrogen, achieve the goal of denitrification, anaerobic pool effective retention time was 2.5 ~ 3.5 h, dissolved oxygen control in 0.5 mg/L or less.

(3) the contact oxidation pool: complete wastewater biochemical treatment, to touch the touch the three levels, the residence time is 8 h, (enhanced equipment contact oxidation time up to 8 ~ 12 h) novel packing for elastic filler, conjunctiva, non-clogging, gas-water contact oxidation pool than about 15:1.

(4) the second pond: biochemical sewage flows into the second pond, the pond for the vertical sedimentation precipitation, surface load as < 1.0 m3 / m2. J h, dredge up to the sludge pool.

(5) the pool disinfection, sterilization device: disinfection pool according to the specification: "TJ14-74" standard for not less than 30 minutes, and if the hospital sewage, disinfection pool can increase the residence time to 1 ~ 1.5 h.

(6) contact disinfection using solid chlorine tablets dissolve way of disinfection, sterilization device can be changed according to the size of the water yield is not following the dosage, achieve water add more medicine, less water less dosing purpose, need other disinfection device can be made separately.

4, Equipment installation, use and maintenance:

Device is placed in the form of two kinds: one, above ground level ground, Second, the floor below. Requirements based on average pressure > 5 t/m2, foundation must be level. Equipment installed under the ground level ground, foundation and ground level ground of relative elevation and equipment of the same height. Site equipment in place is filled with water in the sewage equipment, qualified to prevent groundwater float the equipment. Sewage treatment equipment must be checked before using the equipment system of electric equipment is normal, the fan motor oil is in line with the requirements, until fully qualified. Sewage treatment equipment must be established a set of regular maintenance of system, fan cannot be reversed, regularly check the fan motor oil, fan inlet often clean up. Fan and water pump once every 5000 h operation maintenance.

3, Key technology

The key to the high and new technology is:

a, the overall design the reasonable structure of the reactor tank;

b, prepare special anticorrosive coating process;

c, advanced processing technology
