APPLICATION OF HOME SEWAGE TREATMENT PLANT

Packaged home sewage buried integrated treatment plant is widely used in

• Living communities
• Large and small cottages
• Different type of small factories
• Collective living areas,
• Hospital & Health institute
• School, Collage & Education institute
• And similar sector

Home Sewage Treatment Plant has good livability, low pollution degree, degradability and easy treatment. For example,  The integrated treatment of domestic sewage can help the generation of biological bacteria and promote the reproduction of microorganisms. After the treatment of biological bacteria, the sewage can effectively meet the discharge standard. The underground integrated sewage treatment equipment is generally buried in the ground as a whole, one is to ensure the normal water temperature for the existence and reproduction of biological bacteria; the other is to isolate the air outside the equipment, which is conducive to the external anti-corrosion of the equipment; the third is to reduce the noise of the surrounding environment.

Moreover, the upper part of the equipment is covered with soil, which can afforest vegetation or directly harden into pavement facilities. The underground integrated sewage treatment equipment basically does not occupy land resources and occupies less space. That is to say, The equipment equippe with observation holes, which is conducive to equipment maintenance. The electric control device operates automatically, saving labor cost and convenient operation.

WORKING PRINCIPLE OF HERON HOME SEWAGE TREATMENT PLANT

Meanwhile,  A special filter material is set in the anaerobic filter bed tank in Heron Home Sewage Treatment Plant. Moreover, Through years of technical accumulation, the filter material is designed with high microbial retention, but no blockage and backwashing. Certainly, the water in the anaerobic filter bed flows through the plug flow. Certainly, And the solids separat and stored at the bottom. At this time, through the role of microorganisms in the anaerobic filter bed. Certainly, The anaerobic decomposition of organic matter and denitrification of nitrate nitrogen are completed.

Certainly, The water naturally pushed out from the anaerobic filter bed tank flows into the carrier flow tank. Likewise. Meanwhile, The carrier flow tank is filled with a special flow carrier developed through years of technology accumulation. The carrier has good chemical stability, large surface area, excellent wear resistance and damage resistance, and will not be lost due to crushing. So, it is very suitable for the inoculation, domestication and propagation of microorganisms. Likewise, Through aeration stirring at the bottom of carrier flow tank, the contact efficiency of pollutants and microorganisms is improved, and sufficient oxygen is brought to microorganisms. That is to say, These attached microorganisms decompose organic matter and nitrify ammonia nitrogen, and achieve a larger treatment capacity in a small capacity. Since, the carrier is flowing, there is no need for backwashing at our Sewage Treatment Plant in your home or industry.

THE CARRIER FLOW

Above all, the carrier flow tank is connected with the bottom of the sedimentation tank. Moreover,  a small amount of sludge accumulated at the bottom of the carrier flow tank flows naturally to the bottom of the sedimentation tank. Above all, then is transferred to the debris removal tank by the air lift pump for storage. So, Aar lift pump is a common device to save power and facilitate automatic control, it uses the air power, because there is no need for electrical power.

So, there will be no electrical mechanical failure. When the compressed air is pumped into the vertical pipe in water, the specific gravity of the liquid inside and outside the pipe is different, and the liquid in the pipe is lifted together with the bubbles. As a result, the ascending liquid flows out, air is released into the air. The gas lift pump continuously pumps out a certain amount of liquid, with uniform water output, high efficiency, maintenance free, and actual service life of at least 30 years. So, it is proving our sewage treatment plant is most suitable for your home.

THE SEDIMENTATION TANK AT SEWAGE

However, when the sludge at the bottom of the sedimentation tank at sewage treatment plant at your home premises. most importantly, And it is sent back to the debris removal tank by the air lift pump. The nitrified ammonia nitrogen in the carrier flow tank is also sent back to the debris removal tank to realize the subsequent denitrification reaction. The clear water supernatant in the sedimentation tank is concentrated into the treated water collecting tank through a special structure, and then transferred to the disinfection tank by an air lift pump. most importantly, The supernatant is disinfected by a medicament cylinder equipped with chlorinated disinfection tablets (the dissolving amount of medicament can be adjusted).

However,  after the number of fecal coliforms reaches the standard, it is discharged without any other power, and the initial and maintenance costs are small. So, the equipment system increases the bottom elevation of the discharge pipe by using the discharge air lift pump. So that the effluent does not need to use another pump to enhance the discharge. Above all, The water level in the tank can rise and fall at the same time, buffering the change of inflow flow and reducing the impact load.

At the same time, through calculation, the special flow direction is designed to realize solid-liquid separation. similarly, Through careful design, the odor gas will not occur in the whole domestic sewage treatment device under the action of microorganisms in the tank. Thus way our home sewage treatment plant has wide advantages of automatic operation. similarly, At the same way small installation area and low operation and management cost.
