PE Sewer Septic Tank Specification

As a professional manufacturer of sewer septic tank, our factory mainly produces sewer septic tanks made of PE and SMC. Septic tanks are widely used at home and abroad. In addition to the application of sewer septic tank itself, sewer is also used for the operation and management of sewer septic tank A very important part of the septic tank process. Next, I will introduce to you several problems in the operation and management of septic tanks. Sewer septic tank is the main local treatment structure of domestic sewage. Therefore, strengthening its operation management is of great significance for reducing pollution and protecting urban water environment. But in practice, the author found that there are some deficiencies in its operation and management: small volume, too much sediment, untimely cleaning, etc. In view of the above situation, the author proposes improvement measures such as increasing the water volume, strengthening heat preservation, and clearing out the sediment in time. The practical observations in recent years have shown that the above measures have played a very good role in improving the quality of effluent water and ensuring discharge standards. We mainly produce septic tanks made of pe and smc, so the following form is PE/SMC Sewer Septic Tank Specification.

Several problems in the operation and management of septic tanks

The cost of building a centralized sewage treatment plant ranges from tens of millions to hundreds of millions. In many small and medium-sized cities, there is no centralized sewage treatment facility at present. The sewage is discharged into the water body after local treatment. The most widely used domestic sewage local treatment structures are mainly septic tanks. Septic tanks are generally used in small and medium-sized towns because of their low cost, simple structure, and convenient operation. The sewage is clarified and the sediment is kept and fermented for a long time in the pe septic tank at the same time. After treatment, the ss content in the sewage is reduced by 70%-75%, and the BOD. 5. content is reduced by 30%-35%. Since septic tanks are widely used, strengthening their operation and management is very beneficial to ensure the quality of effluent water and reduce environmental pollution.

Through the investigation of some residential areas in some cities, it is found that there are generally deficiencies in the operation and management of sewer septic tanks, which makes it difficult for the effluent quality of sewer septic tanks to meet the discharge standards. The reasons are as follows:

A large amount of solid inorganic particles flow into the sewer septic tank, reducing its effective water volume. Many newly-built houses need to be refurbished when they are delivered to users, and a large amount of waste water containing high-concentration inorganic particles flows into the sewer septic tank along the drain pipe. According to the initial observation of Xinyang and Luohe residential quarters, the total solid concentration (TS) of the septic tank inlet sewage is as high as 2000 mg/L, and the suspended solids (SS) is as high as 500 mg/L, while BOD5 is relatively small , less than 100 mg/L. Due to the low content of organic matter in sewage, it is almost difficult to form microbial flora, so the initial stage of sewer septic tank use is mainly to purify sewage by sedimentation. However, no one cleans up the solid inorganic particles after deposition, which reduces the effective water volume of the sewer septic tank and correspondingly shortens the residence time of sewage, which brings adverse effects on the later use of the pe sewer septic tank and reduces BOD5. removal rate. After comparative observation before and after cleaning the sewer septic tank, the reduction rate of BOD5 content before cleaning was only 18%, and the reduction rate of Bo content after cleaning was as high as 30%.

The cleaning cycle is too long, which affects its processing effect.

According to our country's practice, the sludge cleaning cycle is generally designed to be 3 to 12 months. However, many sewer septic tank sludge cleaning cycles are much longer than this, ranging from 3 years to 5 years, and some even once built, no one cares about them, resulting in silting. If the sewer septic tank is not cleared in time, some precipitated particles rise together with the air bubbles, resulting in a large amount of suspended solids in the clarified sewage, which reduces the removal rate of ss. The long-term accumulation of sediment will inevitably reduce the effective water volume of the sewer septic tank and reduce the residence time of sewage. Sometimes the sewage is discharged out with almost no residence time in the septic tank due to silting. Obviously, it is impossible to achieve the purpose of effectively degrading organic matter.

Strengthen the operation and management of sewer septic tank

Septic tanks should be cleaned regularly. To this end, a management system can be established in which the street neighborhood committee is responsible for management, charging residents a certain amount of sewage discharge fees, and the environmental protection department regularly monitors and supervises. In addition, improving the degree of mechanization and reducing the labor intensity of workers will also promote the normal operation and management of septic tanks. Therefore, the author envisages burying the sludge suction pipe in the sewer septic tank. When the sludge needs to be discharged, the sludge pump can be used to directly extract it without opening the cover plate. In order to ensure that there are 20% mature sludge in the pool, several small holes can be drilled in a certain part of the pipe. Based on the above ideas, the author increased the volume design of the new residential septic tank by No. 1, and also adopted other related improvement measures. The use observations in recent years show that under normal circumstances, the SS of the sewer septic tank effluent is 80-100 mg/L, and the BOD5 is 80-90 mg/L, both of which have achieved discharge standards.
