Buried integrated domesticsewage treatment equipment

DSW-A equipment scope of application:

This underground sewage treatment is suitable for the residential area, hotel, nursing homes,

schools, mines, factories and such life organic wastewater treatment anything like industrial organic

wastewater treatment.

DSW-A equipment description of the process:

DSW - A device is designed for sewage and anything like industrial organic wastewater treatment, its

main processing method is used at present the mature biochemical treatment technology, biological

contact oxidation, water quality parameters according to general life wastewater design calculation,

press BOD5 200mg/l, average 20mg/l according to water BOD5 design. Six parts: (1) (2) beginning

pond contact oxidation ponds (3) the second pond (4) disinfection pool, disinfection device (5) sludge

pond (6) wind room, fan. Now discussed as follows:

1)beginning early: this equipment pond for pond, sewage leaking Kennedy streaming rising velocity

in traps 0.6-0.7 mm/SEC, precipitate down with air mention to sludge sewage sludge pond. (note:

DSW - A0.5-5m3 / h do not set beginning pond)

2)contact oxidation pool of water after: beginning the sink are analysed to contact pool biochemical

treatment, contact pool three levels, total retention time for more than four hours, heavy-duty

equipment contact oxidation time can reach 6 hours, packing for novel trapezoidal packing, easy

conjunctival, no congestion, packing for 160m2 / m3 than surface area than gas-water contact, pool in

12:1 around. (note: DSW - A0.5-5m3 / h contact pool for level 2)

3)the second pond: the sewage flows into biochemical second pond, the second pond leaking for two

vertical flow velocity parallel-running, rise 0.3-0.4 millimeter/SEC, row mud USES air mention to

sludge pond. (note A0.5 DSW - 5m3 / h sludge artesian - to sludge pool)

4)sterilization tank and disinfection device: according to the standard: "disinfection pool TJ14 74"

standard for 30 minutes, if the hospital sewage, sterilization tank can increase the retention time to 1-

1.5 hours. By using solid chlorine slices of dissolved disinfection way, contact with disinfection

disinfection pool, according to the size of the device can change constantly, &safe-durable

Variable dosage, achieve much more medicine, less water water less the purpose of dosing, need

other device can be made separately.

5)sludge pond: beginning pond, the second pond with all the sludge are DSW - A

lift to the air within the sludge pond aerobic digestion, sludge pond with

supernatant fluid flowing to contact oxidation in the pool before treatment,

digestion, excess sludge rarely after general 1-2 years clean up, cleaning method

can be used FenChe absorption from the sludge pond inspection hole stretch into

sludge after bottom department for suction can. Sinotrans (DSW - A0.5-5m3 / h

sludge using anaerobic digestion)

6)the wind room, fan: equipment DSW - A computer in the wind, the wind above

the sterilization tank engine room with double layer sound insulation, 2 imported A

muffler, fan filter, so runtime without noise. Fan adopts two L ROM dimitrios

blower, it can automatic alternating single machine operation, the fan operation

life of 30,000 hours.

DSW-A equipment Technoloty Parameters Table:

DSW - A equipment all facilities are set in A number of the cabinet, made by the

A3 steel box, the thickness of the steel plate handled, each box 8mm with

seamless steel tube connection, equipment inside and outside all use chemical

product promotion chlorosulfonated polyethylene anti-corrosion coatings,

equipment general besmear brushs the paint 8 way: 2 coat 6 road face paint,

corrosion life generally available for 10 years.

Set of DSW - A design of equipment maintenance cycle for 10 years.
