Septic tanks become an alternative to sewage sedimentation tanks




The production and development process of glass reinforced plastic septic tanks Traditional septic tanks and other sewage and sedimentation facilities are mainly brick-concrete structures and reinforced concrete structures. The water treatment effect is also not good, polluting the surrounding environment, increasing the burden on downstream sewage treatment plants, and the construction procedures are complex and the construction period is long, which cannot meet the requirements of environmental protection departments and construction parties. Therefore, the market urgently needs a more suitable and perfect product. . In this way, glass reinforced plastic septic tanks came into being. Glass fiber reinforced plastic septic tanks, due to the particularity of their raw materials, are lightweight, high strength, non-corrosive, no leakage, excellent water treatment effect, convenient construction and installation, just digging pits and burying, and make up all the shortcomings of traditional septic tanks. Development so far can be divided into four stages: The first stage of the product is square, the top and bottom are slightly smaller, if separated, there are two trapezoids. When processing, two groove-shaped models are processed first, and then they are combined to become a finished product. This product solves the disadvantages of traditional products that are not resistant to corrosion and easy to leak and block, but the tightness is not good enough, and the pressure resistance is average, making it impossible to make large-scale products. The second stage product is basically a horizontal cylinder, but the top and bottom are still designed to be flat. The wheel-shaped concave-convex head was put into use. Because it is a cylindrical mold, the products at this stage are generally connected and combined by using a docking method. The compression performance of this product is better than that of the first stage, but the tightness of the product can be further improved, and the processing procedure of this product is complicated, which is not conducive to factory production. The third stage product is also called corrugated glass septic tank. This product maintains the wheel-shaped head design of the second stage, but the cylinder has been designed as a corrugated cylinder, which is basically formed in one shot, and the tightness and compression resistance have reached a satisfactory level. Some companies are still using this stage of technology. The fourth stage product is the product currently commonly used, and some manufacturers call it an inner corrugated glass septic tank. The shape of the product is smooth and cylindrical, which reduces the force bearing area of the product. However, the square steel is embedded and reinforced at intervals, which resembles undulating waves, so it is also called an inner corrugated glass steel septic tank. The principle and technology of glass reinforced septic tank The glass reinforced septic tank is a treatment facility that removes suspended organics from domestic sewage by using the principles of sedimentation and anaerobic fermentation, and belongs to the primary transitional living treatment structure. Domestic sewage contains a large amount of feces, paper scraps, and pathogens. The suspended solids concentration is 100 ~ 350mg / L, and the organic matter concentration BOD5 is between 100 ~ 400mg / L. The suspended organic matter concentration BOD5 is 50 ~ 200mg / L. After the sewage enters the septic tank for 12 to 24 hours, 50% to 60% of suspended matter can be removed. The precipitated sludge undergoes anaerobic digestion for more than 3 months, which decomposes the organic matter in the sludge into stable inorganic matter, and the perishable raw sludge is transformed into stable mature sludge, which changes the structure of the sludge and reduces The moisture content of the sludge. The sludge is regularly removed for transportation, landfilled or used as fertilizer. The sewage discharge process is similar to the traditional standard septic tank. We divide a large tank into three or four cells. The three cells are called the three-level septic tank, and the four cells are called the four-level septic tank. The sewage is first discharged from the water inlet to the first compartment, and the solids and parasite eggs with a large specific gravity in the first compartment settle down. The anaerobic bacteria in the pool water begin the preliminary fermentation and decomposition, and are treated by the first compartment. The sewage can be divided into three layers: pasty faeceskin, relatively clear faecal fluid, and solid dung.
