Buried integrated sewage treatment equipment

The underground integrated sewage treatment equipment is suitable for domestic sewage treatment and similar industrial sewage treatment in residential areas, restaurants, hotels, nursing homes, schools, mines, factories, slaughter plants, etc.

On the basis of summarizing the operating experience of domestic and international domestic sewage treatment plants, combined with scientific and technological achievements and engineering practice, a complete set of organic wastewater treatment equipment can be designed, which is a series of WSZ series sewage with carbon steel anticorrosion as the main raw material. Processing equipment. Its purpose is mainly to make domestic sewage and similar industrial organic wastewater treated by the equipment to meet the emission standards required by users. The equipment is mainly used for domestic sewage treatment in residential quarters (including villas), high-grade hotels, hospitals, slaughter plants, comprehensive office buildings and various public buildings. The effluent quality treated by the equipment meets national emission standards. A full range of equipment can be buried underground.

Features

Can be buried under the surface, the surface above the equipment can be used as greening or other land, no need to build houses and heating and insulation, fully automatic control, no personnel management, no sludge reflow operation is simple, and maintenance is convenient. The whole equipment processing system is equipped with a fully automatic electric control system, which is safe and reliable in operation. Usually, no special person management is required, and the equipment needs to be maintained and maintained in a timely manner. Low noise, no odor and long service life.

working principle

The buried sewage treatment equipment is a modular high-efficiency sewage biological treatment equipment. It is a sewage biological treatment system that uses biofilm as the main body of purification. It fully utilizes biofilm reactors such as anaerobic biological filter and contact oxidation bed. The utility model has the advantages of large biological density, strong anti-pollution ability, low power consumption, stable operation and convenient maintenance, and the system has wide application prospect and promotion value.

Process Description

The design of the equipment is mainly for the treatment of domestic sewage and similar industrial organic sewage. The main treatment method is to adopt the more mature biochemical treatment technology--biological contact oxidation method. The water quality parameters are calculated according to the general domestic sewage water quality, and the average BOD5 is 200mg/ 1, the effluent BOD5 is designed according to 20mg/1. There are six parts; (1) primary sedimentation tank (2) contact oxidation pond (3) secondary sedimentation tank (4) disinfection tank, disinfection device (5) sludge tank (6) fan room, fan.

Sewage centralized treatment system

1. Technical route – one of the main ways to concentrate on sewage treatment today is to build a sewage treatment plant in rural areas.

The integrated sewage treatment equipment has physical filtration, biodegradation and plant interception, which can effectively remove organic substances and can achieve the purpose of removing N and P through the cooperation of aquatic plants and microorganisms; especially suitable for rural domestic sewage, rivers and Engineering and reuse of natural lake water systems.

2. Application

The centralized sewage treatment system has the advantages of high degree of automation and easy management. It not only has good water quality and high stability, but also meets the national emission requirements in terms of the current status of rural sewage. There are many engineering examples in various centralized sewage treatment methods in China. In addition to land treatment methods, a large amount of construction and management experience has been accumulated.

Advantages and disadvantages

advantage

There are many kinds of buried sewage treatment processes. Under the premise of effluent compliance, the advantages of Zui are:

1. The equipment is buried under the surface, and the above can be greened and the environment is beautiful.

2. The entire device generally does not require dedicated management.

3. It can reduce the floor space, and the parking lot can be built above the equipment. There is no need to build facilities such as factories.

Disadvantage

1. It is not conducive to maintenance. After the equipment fails, it is not convenient to repair and replace. This is usually troubled by the owner zui.

2. It has strong adaptability to the environment, anti-freezing in winter and flood control in summer. The north needs to be buried deep and heat-treated.

Scope of application

1. The amount of water to be treated: the standard type is 1.0 to 80.0 (m3/h), and it needs to be designed separately when it is greater than 80.0 (m3/h).

2. Raw water concentration: BOD5: Standard type ≤250mg/L, enhanced type ≤400mg/L, more than 400mg/L, need to be designed separately.

3. The equipment is mainly applicable to domestic sewage and similar industrial crap water in residential areas, hotels, terminals, airports, shopping malls, nursing homes, schools, factories and mines.

Precautions

Generally, the materials used for buried equipment are of FRP and carbon steel. When purchasing equipment, it is necessary to ask the materials used by the suppliers. When the process and other conditions are the same, the prices of the materials will vary greatly.

Everything speaks with facts. No matter how the supplier of the equipment you provide introduces the superior performance of the equipment, the supplier should be provided with the previous success stories, and then sent to the site to inspect the on-site sewage treatment effect. Although it may delay some time, it is really very important.

Conventional effluent implementation standard

Many units have not specified the standard for sewage treatment when purchasing buried sewage treatment equipment. Under the premise of improving environmental protection requirements in the later period, it will lead to disputes. Because of the different levels of treatment, sewage treatment costs can vary greatly.
