Beautiful rural life pollution Water treatment equipment small-scale
Product features
one . It can treat the comprehensive wastewater of the living system and similar organic sewage. The 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.
two The two-stage biological contact oxidation process adopts the plug flow biological contact oxidation process, and its treatment effect is better than that of the fully mixed or two-stage tandem 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.
three Biochemical tank adopts biological contact oxidation method, and the volume load of its filler is relatively low. The microorganism is in its own oxidation stage, and the sludge production is small, which only takes three months (90 day ) Primary sludge discharge above ( Suck or dehydrate with manure truck to form mud cake for outward transportation ) 。
four The deodorization method of the buried domestic sewage treatment equipment is not only conventional high altitude exhaust, but also soil deodorization measures.
five 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.
six , using Glass Steel and stainless steel structure, with excellent characteristics such as corrosion resistance, aging relief, and long service life fifty More than years.
Small domestic sewage treatment equipment in beautiful countryside Select from the material, which is the integrated sewage treatment equipment pot Body material. At present, carbon steel, glass fiber reinforced plastic, cast iron, aluminum, food grade resin or PVC And other materials. The first three types of materials with good compression resistance can be used as prefilters (central machines), while the last two types of materials with poor compression resistance can only be used at the back end of prefilters (central machines) for direct drinking machines. Among these materials, carbon steel is preferred for compression resistance and corrosion resistance. The price is also relatively high. Food pole resin or PVC The pressure resistance is poor and the price is relatively low. In this method, the oxygen required by microorganisms is supplied by blast aeration. When the biofilm grows to a certain thickness, the microorganisms on the filler wall will undergo anaerobic metabolism due to hypoxia. The generated gas and the scouring effect formed by aeration will cause the biofilm to fall off and promote the growth of new biofilm. At this time, the fallen biofilm will flow out of the pool with the outflow.
Small domestic sewage treatment equipment in beautiful countryside There is no unified limit on the treatment capacity of the sewage system in various countries. The characteristics of water quality and quantity of domestic sewage can be roughly summarized as follows: the water quality and quantity change greatly, the concentration of pollutants and suspended solids is low, the biodegradability of sewage is good, and the treatment difficulty is low. The sewage treatment process should vary according to the different functions of sewage discharged into the water body. The principle of sewage treatment: select a treatment method with stable treatment effect, less sludge production and energy conservation. Septic tanks are generally built in various buildings in the sewage treatment system, so septic tanks should be combined with sewage treatment methods.
Small domestic sewage treatment equipment in beautiful countryside Common treatment process flow of buried integrated sewage treatment system: domestic sewage → grid → domestic sewage regulating tank → sewage pump → buried sewage treatment equipment → discharge. The biological contact oxidation method is used. Its main advantages are short residence time and easy film hanging. It is especially suitable for equipment, equipment buried construction, and the use of glass fiber reinforced plastic materials with good anti-corrosion performance. The service life of the equipment can reach more than 25 years, so it is favored by environmental protection companies and users.
Huaxi River is a tributary of the Yangtze River originating from Banan District. In the past, because the surrounding sewage was directly discharged into the river, the Huaxi River smelled bad. With the promotion of joint efforts to protect the Yangtze River in Chongqing, the sewage treatment in the Huaxi River basin has continued to deepen, and the former smelly ditch has become a popular clean water river. Not long ago, Tuqiao Water Quality Purification Station located at the lower reaches of Huaxi River was put into trial operation, which further guaranteed the full collection, treatment and treatment of sewage in Huaxi River.
