What Is The Quality Of Rotational Molded Septic Tanks?
Advantages: 1. Never leak. It is formed in one step using advanced rotational molding technology, without welding and has good sealing performance. 2. Corrosion resistance, high compressive strength and good earthquake resistance. Using brand-new PE materials imported from abroad. 3. Small footprint. This product occupies about 45% of the area of a traditional septic tank, saving land resources and having flexible site selection. 4. The treatment effect is good. Using microbial technology, there is no need to add other chemicals, which is simple and economical. 5. Long service life. This product is resistant to moisture, acid and alkali, oxidation, high and low temperature without deformation, and can be used normally for more than 50 years. Rotational molding septic tanks are widely used in residential buildings, office buildings, schools, nursing homes, enterprises, workshops, living rooms and other industrial and civil buildings. Compared with similar plastic molding products, rotational molding is stronger and more rigid than injection molding and blow molding. Better than that.
Material: 100% imported food-grade new raw materials, rotomolded in one go, high strength. Never leak. Rotational septic tank structure and technical principles:
① Sedimentation and corrosion area: Domestic sewage is sedimented, and substances with a heavy specific gravity sink to the bottom of the tank for septic treatment. The parts with a small specific gravity float on the upper layer of the water and can be fished out from the cleaning port. At the same time, the wastewater produces septic action at this time, and cultivates a microbial population with strong adaptability and activity, so that some difficult-to-decompose organic matter with complex structure is degraded into easily decomposable substances.
②Partition: Convert direct flow water into circulating water, increase the residence time of sewage in the pool, make the decomposition time of sewage and sedimentation sludge in the pool longer, produce more microorganisms, and decompose and swallow the sewage.
③Filter treatment area: Its function is to further process sewage in this area. Converting COD in sewage into harmless inorganic substances is a key component of the equipment. The process used is an advanced biofilm treatment technology at home and abroad designed and proposed by relevant scientific research units on the basis of extensive research and practice. PE septic tanks are made of high-quality environmentally friendly high-density polyethylene raw materials and are molded and formed in one go, making the septic tank seamless and requiring no welding. This ensures that the septic tank is non-toxic, odorless, pollution-free and fully sealed during manufacturing. , anti-leakage, acid and alkali resistance, corrosion resistance, durability, normal use can last more than 50 years, eliminating the problem of brick septic tanks that are not suitable for acid-base conditions and leakage.
Instructions for installation and use of rotomolded septic tanks
1. Installation
1. Measure the site setting and excavation dimensions according to the models and specifications of various septic tanks required by the customer (about 450mm-500mm wider than the actual size of the product), and connect in series When septic tanks are connected, the spacing between tanks is 400mm, and the excavation depth depends on the height of each type of septic tank. 2. Before digging the trench, power sources, water pumps, measuring instruments and excavation equipment should be prepared, and surrounding protection work should be done.
2. Foundation treatment
1. For general soil quality, a medium-coarse sand foundation layer with a thickness of 100-200mm can be laid on the original soil foundation or the backfilled and compacted foundation. 2. The pits must not be soaked by water. If the pits are indeed soaked by water, all accumulated water and silt in the pits should be removed first, and then be replaced with good dry soil and a medium-coarse sand base layer should be laid.
