large bolted waste water tanks

large bolted waste water tanks

In recent years, the urban sewage treatment in China has developed rapidly, and the wastewater treatment rate has reached more than eighty percent. However, most of the small and medium-sized cities and towns which are strongly contrasted to the sewage discharge, collection and treatment are mostly not matched with the corresponding treatment measures. Today, the NVirotech Environmental Protection Co Ltd is to introduce large bolted waste water tanks.

large bolted waste water tanks device is divided into 6 parts, such as 2 inner and outer ring enamel assembly tank and 5 steel mixed partition wall, separated into 6 parts, such as anoxic pool, first grade aerobic pool, two grade aerobic pool, sedimentation tank, disinfection pool, sludge reservoir and so on.

The inner ring is anoxic pool, the other pool is fan shaped in outer ring, and the anoxic pool connects the first grade through the water through the hole. The aerobic pool, the first grade aerobic pool and the two grade aerobic pool are also connected by the over water holes.

The two grade aerobic pool is connected by the outlet pipe to the central pipe of the sedimentation tank. The effluent of the sedimentation tank is collected through the effluent weir, and the disinfection pool is connected through the pipe, and the disinfection pool has a water outlet pipe. The utility model has the advantages of compact structure, small investment, small land area, simple construction, short construction period, and impact load resistance, and is mainly used in the sewage treatment of small and medium-sized towns.

An integrated large bolted waste water tanks treatment device, which is divided into 6 parts, such as anoxic pool, first grade aerobic pool, two grade aerobic pool, sedimentation tank, disinfection pool, sludge reservoir, etc., through 2 annular enamel assembly tanks and 5 steel mixed walls.

The inner tank is an anoxic pool, and the annular area between the inside and outside tanks is separated into a section. The first grade aerobic pool, two grade aerobic pool, sedimentation tank, sterilizing pool and sludge reservoir are separated by steel mixed wall and fan-shaped outside the anoxic pool;

the base of the device is steel mixing foundation, and the outside tank is installed with climbing ladder and walkway, and the anoxic pool is connected to the first grade aerobic pool, first grade aerobic pool and two grade through the overflow hole. The time of aerobic pool is also connected by over water holes. The two grade aerobic pool is connected to the central pipe of the sedimentation tank through the outlet pipe. The effluent of the sedimentation tank is collected through the effluent weir, and the disinfection pool is connected through the pipe, and the disinfection pool has a water outlet pipe.

A kind of integrated large bolted waste water tanks treatment device, which is described in accordance with the claim 1, is characterized in that the enamel assembly can be assembled with enamel plate, special sealing material, self locking bolt and other materials. Each tank body is spliced by a piece of enameled steel plate, among which each enamel steel is adjacent. The transverse edge of the plate is fitted with a corresponding connection hole and fastened with a bolt. The two plates with overlapping parts are inlaid with soft sealing glue; the tank body is provided with a multichannel reinforcement, and the reinforcing bar is fixed on the fastening fastener at the connecting part of the plate.

It is characterized in that the large bolted waste water tanks is equipped with a climbing ladder and a walkway, and the climbing ladder is located on one side of the outer tank, and the aisle is located outside the top of the outer tank and extends to the inner tank to facilitate the operation and maintenance of the 2.

A kind of integrated large bolted waste water tanks treatment device, described in accordance with the claim 1, is characterized in that the base of the device is 50 cm thickness steel mixing structure, double bi-directional reinforcing bar laying; the enamel assembly tank has no floor, is fixed on the steel mix foundation by the expansion screw and sealed with the special sealant; the concrete foundation is expanded with expansion. Screw fixation of anoxic tank central tube, aerobic tank pipe and aerator bracket, central tank support of sedimentation tank.

A kind of integrated large bolted waste water tanks treatment device, as described in 1, is characterized by the steel mixed structure wall and the tank, the sealing steel plate connection and the sealant seal.

In view of the problems existing in the domestic sewage treatment facilities in small and medium-sized cities and towns, the purpose of the utility model is to provide an integrated device used for the treatment of small and medium-sized towns and towns with enamel assembly body as the main body, to solve the traditional technology with large investment, large land occupation, complex construction, long construction period and poor impact load tolerance. A/O+ suspension packing technology, combined with the technology of large bolted waste water tanks and suspended filler, is combined into an integrated sewage treatment device to achieve biological carbon removal, denitrification, disinfection, sludge storage and other functions, and the treated sewage can reach the standard discharge.

large bolted waste water tanks can be made up of enamel plate, special sealing material and self locking bolt. Each tank body is made up of a piece of enamel plate, which is connected with a relative hole in the lateral edge of each enamel plate and is fastened with a bolt, and the connection place is heavy. The two plates are embedded with soft sealing glue layer, and the tank body is provided with a plurality of reinforcing bars, and the reinforcing bars are fixed on the screw fastening parts of the joints between the plates.

The outside large bolted waste water tanks is equipped with a climbing ladder and a walkway. The climbing ladder is located on the side of the outer tank. The aisle is located outside the top of the outer tank and extends to the inner tank so as to facilitate the operation and maintenance of the operators.

The device is based on a 50 cm thickness steel mixing structure, double bi-directional steel bar laying, no floor in the large bolted waste water tanks, fixed on the steel mix and sealed with special sealant through the expansion screw. On the concrete foundation, the center tube of the anoxic pool, the aerator pipe and the aerator support, the center pipe support of the sedimentation tank are fixed with the expansion screw.

industrial wastewater storage tank

As the aeration process is carried out, the aeration tank is continuously rolled and mixed with sewage, and the gas bubble is cut, the utilization rate of oxygen is increased, and the aeration amount and operation cost are reduced.
