The buried domestic sewage treatment device can be buried below the ground surface, which can be used as green or square land. Therefore, this equipment does not occupy the surface area, does not require building, and does not require heating and insulation. The device is equipped with a fully automatic electrical control system and equipment damage alarm system. The equipment has good reliability, so there is generally no need for dedicated personnel to manage it, only monthly or quarterly maintenance is required.

The AO biological treatment process in this device adopts a push loss biological contact oxidation tank, which has a better treatment effect than fully mixed or two-stage, three-stage series fully mixed biological contact oxidation tanks. The device is equipped with soil deodorization measures, which utilize the upper space of the reinforced concrete structure pool to set up improved soil and air distribution pipes. When the odorous components dissolve in the water contained in the soil through the soil layer, they are then transferred into the soil due to surface adsorption and chemical reactions, and ultimately decomposed by microorganisms to achieve deodorization.

2、 Scope of application

The treatment of domestic sewage in residential areas, hospitals, schools, villa communities, hotels, nursing homes, and other places. The treatment of wastewater from aquatic processing plants, livestock processing plants, fresh milk processing plants, and other production facilities.

3、 Product Features

The DMF series sewage treatment equipment can be buried underground, and the surface can be used as green or square land. Therefore, this equipment does not occupy surface area, does not require building, and does not require heating and insulation.

The DMF series sewage treatment consists of secondary tanks, with the first stage being a reinforced concrete structure with a relatively deep burial depth, and the other group being a steel structure with a relatively shallow burial depth. The steel structure pool adopts the domestically pioneered interpenetrating network anti-corrosion coating for corrosion prevention. It is an interpenetrating polymer formed by the interpenetrating of a rubber network and a plastic network. It is resistant to acid, alkali, salt, gasoline, kerosene, aging, abrasion, and rust. After applying the coating, the anti-corrosion life of the equipment can generally reach more than 15 years.

The DMF series sewage treatment equipment not only adopts conventional blower noise reduction measures (such as vibration isolation pads, mufflers, etc.), but also sets up new sound-absorbing materials on the inner wall of the blower room to reduce the noise level during operation to below 50 decibels, thereby reducing the impact on the surrounding environment.

The DMF series sewage treatment equipment is equipped with soil deodorization facilities. It utilizes reinforced concrete structure to set up improved soil and air distribution pipes in the upper space of the pool body. When odorous components dissolve in the water contained in the soil through the soil layer, they are then transferred into the soil due to surface adsorption and chemical reactions, and ultimately decomposed by microorganisms to achieve deodorization.

The DMF series sewage treatment equipment is equipped with a fully automatic electrical control system and equipment damage alarm system. The equipment has good reliability, so there is no need for dedicated personnel to manage it, only monthly and quarterly maintenance and upkeep are required.
