Septic tank Septic tank working principle: Septic tank is an oxygen-free (Oxygen) condition using anaerobic micro-degradation to make organic matter in sewage to be purified (chǔ lǐ). 原则以不影响建筑基础即可；一般距离生活饮用水池不得小于10m.距离地下取水构筑物不得小于30m． The principle of Hohhot septic tank is that it does not affect the foundation of the building; generally, the distance from the drinking water tank should not be less than 10m. The distance from underground water intake structures should not be less than 30m. When the building foundation plane is higher than the septic tank foundation plane, the outer wall distance of the septic tank should not be less than 2m. When the building foundation plane is lower than the septic tank base plane, the net distance of the septic tank from the building wall should not be less than 5m .
A septic tank is a treatment facility that uses the principles of sedimentation and anaerobic fermentation to remove suspended organic matter from domestic sewage. It belongs to the primary transitional life treatment structure. Domestic sewage contains a large amount of feces, paper scraps, pathogens ... The suspended solids concentration is 100 ~ 350mg / L, and the organic matter concentration BOD5 is between 100 ~ 400mg / L, among which the suspended organic matter concentration BOD5 is 50 ~ 200mg / L. L. After the sewage enters the septic tank for 12 to 24 hours, 50% to 60% of suspended matter can be removed. Glass reinforced septic tank is a device made of synthetic resin as the base and made of glass fiber reinforced materials, which is specially used to treat domestic sewage. Hohhot Cistern
It is mainly applicable to domestic sewage purification equipment for civil buildings such as industrial enterprise living rooms and urban residential quarters. Hefei Shuangqiang glass reinforced septic tank is a composite material product actively promoted by the country. Its advantages such as light weight, high strength, good toughness, corrosion resistance, bright color, and smooth finish reach mirror effect, have far surpassed ceramics, hard plastic, steel Similar products of similar materials are widely used in chemical, petroleum, construction, textile, aviation, marine, transportation, electric power, metallurgy, machinery, medical, food, paper, environmental protection and other fields. Under anaerobic conditions, the anaerobic special structure in sewage: Capsules, flagella, fungus hairs decompose organic substances such as carbon (C) water compounds (Carbohydrate), protein (fat) and fat (fat) to produce organic The acid is then further fermented under the action of methanogens to form methane, oxidation carbon, and hydrogen (Hydrogen), thereby purifying the sewage. Such as septic tanks, sludge anaerobic digestion, anaerobic ponds, etc. The BOD load of wastewater from anaerobic treatment is relatively high. For example, the BOD load of anaerobic digestion is generally 3.5kg / (m3 · d), the screening rate can reach more than 90%, and its treatment cost (expense) is lower than aerobic treatment. It is one of the good treatment methods for domestic sewage sludge, high-concentration organic industrial wastewater and feces. Anaerobic glass tempered septic tank adopts the new technology of up-and-down baffle sludge tank and anaerobic filter. It has good hydraulic conditions and good mixing effect. There are few dead angles in the septic tank for environmental protection. The contact is beneficial to the decomposition of organic matter. The removal rate of COD is 55% and the removal rate of suspended COD is 80%, which is more than double the traditional processing capacity. The design of the upper and lower partitions of the compartment is without mixing equipment (shèbèi), no power, simple structure, but can make the original DC flooding in the pool into circulating flooding, which makes the contact oxidation time of sewage and filler longer, organic matter Higher degree of degradation. At the same time, due to the stepwise reduction of the influent sludge load, the agitation of the biogas is also minimized step by step, and a large amount of sludge will not be lost due to the anaerobic sludge bed inflate.

Application scope of septic tank: It is mainly applicable to domestic sewage purification equipment for industrial buildings (Company) living rooms and urban residents living quarters. It plays an active role in intercepting and precipitating large particles of impurities in sewage, preventing clogging of sewage pipes, and reducing buried depth of pipes. At present, domestic sewage is becoming increasingly serious to the environment. Based on the introduction of foreign domestic sewage treatment technology, this product is combined with the company's scientific research results and engineering practices, using polymer composite materials and factory production. It is an efficient ( Refers to high-efficiency), energy-saving, lightweight, and inexpensive domestic sewage treatment equipment. It successfully replaced (substitute one substance with another substance (mostly the weaker one)). Traditional bricks and steel septic tanks polluted groundwater and affected due to seepage and poor operating conditions ( influence) the safety of surrounding buildings. This product uses the gravity flow of water, does not require any external power and operating costs, saves energy, is easy to manage, and has good social, environmental and economic benefits.
