MBR Membrane Bioreactor Wastewater Treatment Plant (MBR)

Integrated sewage treatment equipment for the user to provide a complete organic buried set of sewage treatment equipment. Its primary purpose is to make life sewage and anything like industrial organic wastewater treatment by the equipment to user's emissions standards. Three generations of glass fiber reinforced plastic materials for the main in the structure of the craft combination, new HDS retail - F equipment is with manufacturing wastewater treatment process and on a new level in this field, and make the sewage treatment equipment reaching the international advanced level.

Integrated sewage treatment equipment is currently a mature biochemical treatment technology contact oxidation method, is mainly to the sewage and industrial organic wastewater, similar to the processing, adopts integration design, occupies little space, low operating cost, equipped with automatic control system, convenient operation and maintenance. Water quality design parameters according to the general life sewage water quality and water design calculation, the average according to 200mg/l for: BOD BOD 20mg water plan, according to project/l, six parts: (1) beginning pond; (2) contact oxidation ponds: (3) the second pond (4) sterilization tank, sterilization device; (5) sludge pool; (6) of the room.

Integrated sewage treatment equipment is a pond, I, II level contact oxidation pool, the second pond, sludge pond and the equipment, concentrated in the body and I, II level contact oxidation pool for drum wind aeration, make contact oxidation and activated sludge effective combination, also with the advantage of the two, and overcome the shortcomings of both, sewage treatment to a higher level, its have prominent advantages are:

1, impact resistant load ability. Contact oxidation in the average residence time more than six hours;

2 with nitrogen, phosphorus ability, and can adjust the equipment to deal with the structure of industrial wastewater, sewage, urban sewage capability;

3, contact oxidation in the pool for the combination of packing more soft filler, qualitative light, high strength, physical and chemical stability, high spicific surface adhesion ability strong, biofilm, sewage and biofilm contact high efficiency;

4, contact oxidation in the pool are using aerator, drum wind aeration fibre bundle moved, aeration constantly bleaching evenly, microbial growth mature, has activated sludge characteristic;

5, outlet water quality stable, and easy to deal with less sludge production;

Six, can put into equipment submersible pumps and cut down engineering investment; among

7, equipment can be set in the ground, can also be buried underground. Buried underground, the upper covered can be used for afforestation, the factory covers an area of less, ground structures is less;

8, easy to complete automatic control, management, simple operation.

Equipment range:

1, processing water: standard for 1.0 ~ 80.0 (m3 / h), greater than 80.0 (m3 / h) prior design.

2, raw water concentration: BOD5: standard acuities, 250mg/L 400mg/L reinforced acuities, more than 400 mg/L should further design.

3, equipment is mainly applied in residential area, hotel, docks and airports, shopping mall, nursing homes, schools, factories and industries of sewage and similar industrial crap water.

Sewage treatment equipment material selection:

1, all stainless steel structure

2, the A3 steel structure

3, (Q235 steel, glass reinforced plastics (FRP)) composite structure

4, glass reinforced plastics (FRP) circular

5 and reinforced concrete structure

Equipment process description:

Equipment design is mainly to the sewage and industrial organic wastewater treatment. Its main processing method is used at present the mature biochemical treatment technology contact oxidation ponds. According to the sewage water quality design parameters for 250mg/L, BOD5 effluent BOD5 20mg/L for calculation. There were seven parts: (1) the pond of early; (2) the anoxic pool; (3) contact oxidation pool; (4) the second pond; [disinfection pool, disinfection device; 6] sludge pool; [7] of the room.

1). the beginning pond for vertical: beginning the pond, sewage leaking in traps streamed rising velocity of 0.3 ~ 0.4 millimeter/SEC, precipitate down the sludge promoted to sludge pond. SFW - 5 types and the following equipment not setting a pond at the beginning

2).Anoxia pool: anoxic pool for nitrogen treatment and Settings, in the pool YDT type three-dimensional elastic packing set, as the carrier of denitrifying bacteria, denitrifying liquid ammonia nitrate back in normal oxygen and the acid in the denitrifying bacteria, under the action of reductive into nitrogen, achieve the purpose of nitrogen, oxygen pool for 2.5 ~ effectively retention time h, dissolved oxygen control in 3.5 more than 0.5 mg/L.

3).Contact oxidation ponds: sewage artesian to contact pool biochemical treatment, contact pool are divided into 3 level, residence time, (for reinforced equipment contact oxidation time can reach 8 ~ 12h) packing for novel elastic packing, easy conjunctival, don't jam, contact oxidation ponds gas water than in 15:1 around.

4).The second pond: the sewage flows into biochemical second pond, the second pond for vertical flow precipitation, the surface load for < 1.0 m3 / m2. J h, row mud promoted to sludge pond.

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

By using solid chlorine piece contact disinfection disinfection way, disinfection of dissolved according to the size of the device can not following the change &safe-durable dosing amount to much less water more medicine, the purpose of water less dosing, need other disinfection device can be made separately.

Electronic control:

Sewage treatment equipment system for automatic microcomputer control, simultaneously has the fault alarm instruction function

Equipment installation, use and maintenance:

Equipment placed for two: a form, floor above; Second, floor below.

Based on average > 5-ton/ m2 artesian requirements based must level . The equipment is installed in the floor, and the ground under based the relative elevation and equipment highly the same. Site equipment in place in sewage equipment is within qualified filled with water, in case the top. The equipment groundwater

Sewage treatment before using equipment, must check the equipment system of electric is normal, the fan motor oil requirements, whether until completely qualified.

Sewage treatment equipment must be established a set of regular maintenance system, fan can not be reversed, regular inspection fan motor oil, fan inlet often cleaning. Fans and pumps 5000h serviced once every operation.
