matters needing attention:

There are usually two types of materials used for buried equipment: fiberglass and carbon steel. When purchasing equipment, it is necessary to inquire with the supplier about the materials used. When the process and other conditions are the same, the price of different materials will vary greatly.
Go to the supplier's successful case site to observe the effect
Everything should be based on facts. No matter how the supplier of the equipment introduces its performance, they should provide previous successful cases and then send people to inspect its on-site sewage treatment effect. Although it may delay some time, it is indeed crucial.
Agreed execution standards for water discharge
Many units fail to specify the standard for sewage treatment in the contract when purchasing buried sewage treatment equipment, which can lead to disputes in the future when environmental protection requirements are raised. Due to different levels of treatment, the cost of sewage treatment can vary greatly.
Compare and sign contracts before purchasing, and specify the payment process.
Choose several suppliers as references, and then compare their adopted processes, successful cases, prices, and other factors comprehensively.

With the growth of the economy and population, the control of natural pollution has received increasing attention from humans. Based on the summary of the operating experience of sewage treatment equipment at home and abroad, combined with our company's own scientific research achievements and engineering practice, we have designed a complete set of organic wastewater treatment equipment that can be buried underground. This equipment adopts advanced technology and manufacturing techniques at home and abroad to produce products mainly made of fiberglass and carbon steelTDMType series integrated sewage treatment equipment. The main purpose is to meet the discharge standards required by users after treating domestic sewage and similar industrial organic wastewater with this equipment. This device is mainly used in residential areas(Including villa communities)The wastewater treatment of hotels, hospitals, comprehensive office buildings, and various public buildings, the effluent quality treated by this equipment meets the discharge standards.

Equipment features

1. Buried below the surface, the surface above the equipment can be used for greening or other purposes, without the need for building houses, heating, or insulation.

2. The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. Adopting new methods in the poolType elastic three-dimensional filler, with a large specific surface area, is prone to biofilm formation and detachment by microorganisms. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in air in water.

3. The biochemical tank adopts the biological contact oxidation method, which has a relatively low volume load of the filling material, and the microorganisms are in their own oxidation stage, resulting in low sludge production. It only takes more than three months (90 days) to discharge the sludge (using fecal trucks to suction or dehydrate into sludge cakes for external transportation).

4. The deodorization method of this buried domestic sewage treatment equipment not only uses conventional high-altitude exhaust, but also includes soil deodorization measures.

5. The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required.

The integrated sewage treatment equipment is suitable for the treatment and reuse of domestic sewage in residential areas, villages, towns, office buildings, shopping malls, hotels, restaurants, sanatoriums, government agencies, schools, military units, hospitals, highways, railways, factories, mines, tourist attractions, and similar organic wastewater from small and medium-sized industries such as slaughter, aquatic product processing, and food. The sewage treated by this equipment meets the Grade B standard of the comprehensive sewage treatment discharge standard.
