Vacuum drainage technology is on the move

The application of vacuum environmental protection toilet field

1. Introduction

With the acceleration of urbanization and the enhancement of people's awareness of environmental protection, the inadequacy of traditional toilet systems has become increasingly apparent. Traditional toilets not only consume a lot of water, but also tend to cause odors and hygiene problems. In this context, vacuum drainage technology has gradually been introduced into the field of environmental protection toilets, especially in the mobile vacuum environmental protection toilets has shown great application potential.

2. Vacuum drainage technology overview

Vacuum drainage technology is a technology that quickly transmits waste water and dirt from the drainage point to the treatment system through vacuum suction. The core of this technology is the use of negative pressure difference, so that waste water and sewage can be efficiently pumped away without the help of gravity. This kind of system usually includes vacuum pumping station, vacuum pipe, vacuum toilet and water storage device, sewage tank and other parts.

3. Advantages of vacuum drainage technology

3.1. Remarkable water-saving effect

Vacuum drainage system can greatly reduce water consumption compared with traditional gravity drainage system. Traditional toilets usually require 6-9 liters of water per flush, while vacuum toilets only need 0.5 to 1 liters of water per flush, which greatly saves water resources.

3.2 Environmental hygiene

Due to the rapid sewage capacity of vacuum drainage technology, it can effectively prevent dirt from remaining in the drainage pipe, reduce the production of odor, and also reduce the risk of bacterial growth. This makes the vacuum environmental protection toilet in places with high sanitation requirements (such as public places, tourist attractions, etc.) is particularly suitable.

3.3 Strong adaptability

Vacuum drainage technology does not rely on gravity drainage system and can be installed and used in various terrain conditions. This makes it particularly suitable for portable toilets, which can be flexibly arranged and used in a variety of temporary places (such as construction sites, wilderness campsites, large-scale event sites, etc.).

4. Mobile vacuum toilet application scenarios

4.1 Urban modular vacuum toilet

Urban modular vacuum toilets can be installed and disassembled quickly through container-type design, and are suitable for public places such as parks and squares. Due to the limitations of the urban water supply and sewage system, the water supply and sewage of traditional toilets are difficult, and the vacuum toilet with its advantages of saving water and reducing the amount of sewage, the same water can be flushed more times, which greatly reduces the cost of use and reduces the dependence on municipal infrastructure. These toilets can not only operate efficiently in a limited space, but can also be flexibly arranged according to demand, providing urban residents and tourists with convenient toilet choices.

4.2 Environmental protection vacuum toilet in scenic area 

Tourist attractions often face problems of large number of tourists and imperfect water supply and sewage systems. Traditional toilets are difficult to cope with the demand for use during peak periods and are prone to environmental pollution. Environmental protection vacuum toilets in scenic spots use vacuum drainage technology to save water and reduce the amount of sewage. The same water can be flushed more times, reducing the difficulty of sewage treatment. The installation of vacuum toilets is flexible, not limited by terrain, can adapt to various natural environments, provide environmental protection and sanitary toilet facilities, and enhance the experience of tourists and the environmental protection image of the scenic spot.

4.3 Vacuum toilet in the field of troops

Troops are usually required to set up temporary living facilities when they are on field duty. Water supply and sewage are limited in the field, the use of traditional toilets is greatly limited, water replenishment is difficult and sewage treatment is complicated. The characteristics of water saving and low sewage amount of vacuum toilets make them especially suitable in the field environment. Vacuum drainage technology not only reduces the demand for water resources, but also efficiently treats wastewater and provides reliable sanitation. These toilets are easy to install and can be quickly deployed in a variety of field environments, providing soldiers with a clean and sanitary toilet environment to ensure their health and combat effectiveness.

4.4 Fire lavatory vacuum truck

At fire rescue sites, it is usually necessary to provide convenient toilet and washing facilities. Traditional lavatory facilities are heavy in water consumption and complicated in sewage treatment, making it difficult to meet the needs of emergency rescue. Through vacuum drainage technology, the fire washing vacuum truck saves water, reduces the amount of sewage, and improves the use efficiency of the on-board facilities. The vacuum toilet can operate efficiently in the case of limited water supply and sewage conditions, provide the necessary hygiene guarantee, and ensure the health and work efficiency of rescue workers.

4.5 Mobile vehicle vacuum toilets

In long-distance buses, motorhomes and other mobile vehicles, traditional toilets have limited space and complex water supply and sewage systems. Vacuum drainage technology can achieve efficient wastewater treatment in a limited space to ensure a clean and sanitary environment inside the vehicle. The vacuum toilet uses less water, and the same water can be flushed more times, reducing the need for water refill and the difficulty of sewage treatment. The characteristics of low water consumption and low sewage volume improve the endurance of the vehicle, reduce the trouble of frequent stopping and replenishing, and improve the comfort and convenience of passengers.

4.6 Ocean-going ships and aircraft vacuum toilets

During long voyages or flights, the traditional toilets face difficulties in replenishing and discharging water. Vacuum drainage technology ensures environmental hygiene and reduces waste water treatment pressure by saving water and reducing the amount of sewage. Vacuum toilets are able to operate efficiently in a limited space and provide a comfortable toilet experience. With its advantages of water saving and low sewage volume, it ADAPTS to the needs of long-term journeys and ensures the health and comfort of passengers and crew.

4.7 Vacuum environment-friendly toilets on site

Construction sites usually have limited water supply and sewage conditions, and traditional toilets are easy to cause environmental pollution, difficult to replenish water and a large amount of sewage, and high cost of use. The vacuum environmental protection toilet on the construction site uses vacuum drainage technology, saves water, reduces the amount of sewage, is easy to install, and can adapt to various terrain conditions. The vacuum toilet provides a clean and sanitary toilet environment, reduces the waste of water resources and the burden of sewage treatment, meets the requirements of green construction, and improves the working environment and health protection of workers.

4.8 Vacuum toilets in campsites

Campgrounds are often located in remote areas with inadequate water and sewer systems. Traditional toilets are difficult to replenish water and complicated to treat sewage, which easily causes pollution to the natural environment. Vacuum toilet through vacuum drainage technology, water saving, low sewage, the same water can be flushed more times, reduce the impact on the natural environment. The installation of vacuum toilets is flexible and can adapt to various campsite environments, providing environmentally friendly and sanitary toilet facilities, enhancing the camping experience and ensuring the comfort and health of campers.

5 Vacuum equipment

There are two forms of vacuum toilet equipment available today: single-unit vacuum toilets and centralized vacuum toilets at pumping stations.

5.1 Introduction to the single vacuum toilet

The single vacuum toilet is the high concentration of feces and urine sewage pumped to the sewage main pipe using the principle of air pressure, and then step by step pressure discharged to the sewage treatment system, users can choose any number of squatting toilets, toilets, urinals, each toilet pumping and sewage system, separate control, do not interfere with each other, will not affect the normal use of other toilets due to the failure of individual toilets;
