Buried integrated sewage treatment equipment is a recent sewage treatment commodity that can be buried underground. The surface above the machinery can be used for landscaping or other commercial purposes, without the need for building houses, heating and insulation. It is automatically operated and does not require employee management. There is no need for sludge to flow back for convenient use and maintenance. It has a wide range of applications and very good solution effects.

Based on the operational experience of sewage treatment equipment in various countries around the world, combined with scientific research achievements and project practice activities, a complete set of buried and installable organic sewage treatment equipment is designed, which is the WSZ series of sewage treatment equipment with carbon steel corrosion prevention as the primary raw material. Its main significance is to ensure that domestic sewage treatment and similar industrial production organic sewage meet the environmental standards specified by the customer after being treated by this facility. This facility is mainly used for sewage treatment in residential communities (including villa communities), high-end hotels, hospital clinics, slaughterhouses, comprehensive office buildings, and various civil buildings. The effluent water treated by this facility meets national environmental standards. The entire equipment can be installed underground.

Characteristics of buried integrated sewage treatment equipment machinery and equipment

It can be buried underground, and the surface above the machinery and equipment can be used as landscaping or other commercial land, without the need for building houses, heating and insulation. It is automatically operated and does not require employee management. It is convenient to use and maintain without mud flowing back. All machine equipment solutions are equipped with automatic control systems, which can operate reliably. Generally, there is no need for professional personnel to manage them, and only timely protection and maintenance of the machine equipment are required. Low noise, no odor, and long service life.

Principle of buried integrated sewage treatment equipment

Buried sewage treatment equipment is a modular design of high-efficiency wastewater biological treatment equipment, which is a wastewater biological solution system software mainly based on biofilm cleaning. It fully utilizes the characteristics of high biological density, strong pollution resistance, low driving power consumption, smooth actual operation, and convenient maintenance of biofilm reactors such as anaerobic fermentation biofilters and touch air oxidation beds, which promote the wide application prospects and promotional value of the system.

Processing technology of buried integrated sewage treatment equipment

The development of machinery and equipment mainly focuses on the treatment of domestic sewage and similar industrial organic wastewater. The key solution is to use a relatively complete biochemical solution technology - biological touch air oxidation method. The main parameters of the water body are calculated according to the general design scheme for domestic sewage treatment, with an average BOD5 concentration of 200mg/1 and a water output BOD5 concentration of 20mg/1. It consists of six parts in total; (1) Primary sedimentation tank (2) Contact oxidation tank (3) Secondary sedimentation tank (4) Disinfection tank, disinfection and sterilization equipment (5) Sludge tank (6) Fan room, centrifugal fan. Discussion on Underground Sewage Treatment Equipment

Underground integrated sewage treatment equipment wastewater treatment system

1. One of the specific methods for centralized sewage treatment nowadays is to build sewage treatment stations in new rural areas, which is a technical solution.

The integrated wastewater treatment equipment has processing technologies such as physical filtration, biological dissolution, and green plant interception, which can effectively remove organic matter. At the same time, it can achieve the goal of removing N and P based on the cooperation between aquatic flowers and microorganisms; Especially suitable for engineering projects such as rural domestic sewage treatment, processing, treatment, and recycling of river embankments and natural lake water bodies. The removal of organic pollutants and permanganate index by sewage treatment equipment depends crucially on the AO biological processing technology in the machinery and equipment. The principle is at level A.

Due to the high concentration of organic matter in wastewater, microorganisms are in a state of insufficient oxygen. At this time, microorganisms are facultative microorganisms, which convert organic nitrogen in wastewater into NH3-N. At the same time, organic carbon is used as an electronic device supplier to convert NO2-N and NO3-N into N2, and a portion of organic nitrogen sources and NH3-N are also used to generate new somatic chemicals. Therefore, A-level tanks not only have a certain organic matter removal effect to alleviate the organic load of activated sludge, which is conducive to the development of biological nitrogen fixation, but also use the higher concentration of organic matter in the raw water for nitrification, and finally remove nitrogen from the eutrophic environment of the water

At level O, although the concentration of organic matter has significantly decreased, there is still a certain amount of organic matter and higher NH3-N present. In order to further oxidize and decompose organic matter, and at the same time, biological nitrogen fixation can be carried out smoothly while the carbon enhancement effect is in progress, an aerobic biological contact oxidation tank with lower organic load is set up at level O. In the O tank, aerobic microorganisms and autotrophic bacteria (water quality stabilizers) are specifically stored. Organic matter carbon caused by organic matter dissolution or CO2 in the air are used as nutrient sources to convert NH3-N in wastewater into NO2-N, NO3-N. Part of the overflow water from the O tank flows back to the A tank, providing electrons for the A tank. Device acceptor, based on nitrification, ultimately removes nitrogen environmental pollution.
