Special fiberglass septic tank for sewage treatment

Introduction to Glass Tempered Septic Tank for Sewage Treatment:

A septic tank is a device that processes feces and filters and settles them. The principle is that the solidified material decomposes at the bottom of the pool, and the hydrated material in the upper layer flows away into the pipeline, preventing pipeline blockage and giving sufficient time for the solidified material (feces, garbage, etc.) to hydrolyze. Septic tank refers to a small-scale treatment structure that separates and settles domestic sewage and anaerobically digests sludge.

Chemical principle of glass reinforced plastic septic tank for sewage treatment:

Septic tank is a treatment facility that uses the principles of sedimentation and anaerobic fermentation to remove suspended organic matter from domestic sewage. It is a primary transitional living treatment structure. Domestic sewage contains a large amount of feces, paper scraps, and pathogenic insects. The suspended solids concentration is 100-350mg/L, and the biochemical oxygen demand (BOD5) is between 100-400mg/L. Among them, the suspended biochemical oxygen demand (BOD5) is 50-200mg/L. The sewage enters the septic tank and undergoes 12-24 hours of sedimentation, which can remove 50% -60% of suspended solids. The settled sludge undergoes anaerobic fermentation and decomposition for more than 3 months, which breaks down the organic matter in the sludge into stable inorganic substances. The perishable raw sludge is converted into stable mature sludge, changing the structure of the sludge and reducing its moisture content. Regularly remove the sludge for transportation, landfilling, or use as fertilizer. Requirement: The calculated volume of the sedimentation and decay parts of the septic tank should be determined in accordance with Articles 4.8.4-4.8.7 of the "Code for Design of Building Water Supply and Drainage" (GB50015-2003). The retention time of sewage in the septic tank should not be less than 36 hours. For sewage treatment systems without sludge disposal, the capacity of the septic tank should also include the capacity for storing sludge.

Special fiberglass septic tank for sewage treatmenttechnological process:

Septic tank is a treatment equipment that uses sedimentation and anaerobic fermentation principles to remove suspended organic matter from domestic sewage. The corrugated glass reinforced plastic manure container is equipped with a partition inside, and the holes on the partition are staggered up and down, which is not easy to form short flow, and divides the entire lower tank into three parts; The third stage anaerobic chamber, the second stage anaerobic chamber, and the clarification chamber are interconnected at the bottom of the first and second stage anaerobic chambers, and are filled with "MDS specific special packing" inside. This separation reduces the contact time between sewage and sludge, ensuring that the two processes of acidic fermentation and alkaline fermentation do not interfere with each other. At the same time, the presence of fillers increases the contact surface area between sewage sludge and anaerobic bacteria, greatly improving reaction efficiency.

Environmentally friendly septic tanks have the performance characteristics of traditional oil separators, oil-water separators, and sedimentation tanks

1、 The product barrel body is made of high-strength acid and alkali resistant materials such as glass fiber and organic resin, which are formed in one go and have good sealing performance. It will never cause fracture damage or floating slag layer in the tank due to foundation settlement, completely solving the problem of underground water pollution in brick septic tanks, ensuring the reliable operation of septic tanks and the function of anaerobic manure;
2、 The product with high compressive strength has a reasonable structural design and uniform compression. After more than 200 cycles of testing, the truck does not settle or deform when rolled on the upper part;

3、 The product has a small footprint, occupying about 60% of the traditional brick septic tank, saving land resources and featuring flexible site selection;

4、 Easy installation and construction, can be freely combined and installed according to site needs, and can be put into use within two hours after installation;
5、 The treatment effect is good. The compartment board of this product is designed with staggered layers, changing from the original direct flow type to a circulating type. The substrate transfer is smooth, and the application of anaerobic biofilter (AF) packing system intercepts more biomass. The sewage treatment capacity is more than twice that of traditional septic tanks with the same volume;

6、 Long service life: This product is resistant to moisture, acid and alkali, oxidation, high and low temperatures without deformation, and can be used normally for more than 50 years;

7、 The overall cost of reinforced concrete structures is 80-90% of the low economic indicators, and it is an environmentally friendly product vigorously promoted by the urban construction department.
　　

Application scope of buried fiberglass septic tank for sewage treatment:　　

1. This product is a supporting facility for the preliminary treatment of domestic sewage in industrial and civil buildings such as residential buildings, office buildings, schools, sanatoriums, enterprise workshops, and living rooms in residential communities;

2. This product is calculated and applied according to the separation system of washing wastewater and fecal sewage in indoor drainage system;

3. Before the inlet and outlet pipes of the septic tank, a drainage inspection should be conducted.
