Small domestic sewage in villages Water treatment equipment project
With the growth of economy and population, human beings pay more and more attention to the pollution of nature. On the basis of summing up the operating experience of domestic sewage treatment devices at home and abroad, combined with our own scientific research achievements and engineering practice, we designed a complete set of buried organic wastewater treatment devices, Its equipment adopts advanced technology and manufacturing technology at home and abroad in the late 1990s to produce Glass Integrated sewage treatment equipment with steel and stainless steel as main raw materials. The main purpose is to make domestic sewage and similar industrial organic wastewater reach the discharge standard required by users after being treated by the equipment.
Small domestic sewage treatment equipment project in villages The equipment is mainly used for domestic sewage treatment of residential quarters (including villa communities), high hotels, hospitals, comprehensive office buildings and various public buildings. The effluent quality treated by the equipment meets the national discharge standards. The whole set of equipment can be buried underground, so it is also called "underground domestic sewage treatment equipment".
The buried domestic sewage treatment equipment of our company adopts internationally advanced biological treatment process to remove BOD five 、COD、NH three -N in one, with stable and reliable technical performance, good treatment effect, low investment, less land occupation, convenient maintenance and other advantages. Our company can also provide reclaimed water reuse equipment according to customer requirements.
Small domestic sewage treatment equipment project in villages Product features
1. Domestic sewage treatment equipment is buried below the surface, and the surface above the equipment can be used as greening or other For land use, there is no need for building houses, heating and insulation.
2. The two-stage biological contact oxidation process adopts the plug flow biological contact oxidation process, and its treatment effect is better than the fully mixed or two-stage series fully mixed biological contact oxidation tank. It is smaller than the activated sludge tank, has strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not produce sludge bulking. New elastic solid is used in the pool filler The specific surface area is large, and the microorganism is easy to hang and remove the membrane. Under the same organic load conditions, the organic matter removal rate is high, which can improve the solubility of oxygen in the air in water.
3. Biological contact oxidation method is adopted for biochemical tank. The volume load of its filler is relatively low, and the microorganism is in its own oxidation stage, so the sludge production is small. It only takes more than three months (90 days) to discharge the sludge (pumped or dehydrated into mud cake and transported out).
4. The underground domestic sewage treatment equipment is provided with soil deodorization measures in addition to conventional high altitude exhaust.
5. The whole equipment processing system is equipped with a fully automatic electrical control system and an equipment fault alarm system, which is safe and reliable in operation. Usually, there is no need for special personnel to manage the equipment, but only the timely maintenance of the equipment.
Small domestic sewage treatment equipment project in villages There are many sewage treatment processes used at home and abroad, including activated sludge process and biofilm process. The common aeration method, oxidation ditch method, A/B method, A two /The O method belongs to the former, while the biological rotary table and contact oxidation method belong to the latter. The integrated sewage treatment equipment is a device that integrates the primary sedimentation tank, I and II level contact oxidation tank, secondary sedimentation tank and sludge tank, and carries out air blast aeration in the I and II level contact oxidation tank to effectively combine the contact oxidation method and activated sludge method. At the same time, it has the advantages of both, overcomes the disadvantages of both, and further improves the sewage treatment level.
"A good ecological environment is a more inclusive well-being of people's livelihood. We should adhere to the principle of people first, planning leadership, system concept, result orientation, and adjusting measures to local conditions, and promote rural domestic sewage treatment at a high level." Xu Xiaoxia, secretary of the Party Leadership Group and director of the Provincial Department of Ecological Environment, said that the Ministry of Ecological Environment door We should adhere to the principle of "two hands and two promotions", combine theme education with the promotion of central work, constantly strengthen policy guidance, strengthen guidance, assistance, demonstration and promotion, make every effort to improve the level of rural domestic sewage treatment, and strive to improve the rural living environment, so that the majority of farmers can really feel the changes in their families.
