Biological deodorization technology mainly deals with the odor pollution caused by organic compounds, which appeared as early as the 1950s. Its main principle is the metabolic mechanism of microbial decomposition, oxidation, synthesis, etc., which converts substances containing odor into carbon dioxide, water, 4-valent hydrogen oxides, etc. The transformation process from organic to inorganic substances can achieve odor control. There are two common types of biological deodorization technology: (1) biological filter. The so-called "biological filter" refers to the pre humidified odor passing through the biological filter bed and being converted into a biofilm fixed on the surface of the filter material. The microorganisms in the biofilm can meet the work of oxidation and decomposition, converting organic matter into inorganic matter. But the drawbacks of this technology are obvious, it cannot achieve persistent operation, and the phenomenon of local compaction is very serious. (2) Biological drip filtration tower. The principle of this technology is that after pollutants are circulated and absorbed, they are continuously transported to the biofilm to achieve microbial decomposition and oxidation. However, when pollutants exceed the load of the biofilm, there will be an increase in pressure loss, leading to an anaerobic state inside the membrane and the formation of odorous gases such as hydrogen sulfide and organic acids.

1、 Introduction to Hospital Sewage Treatment Equipment
On the basis of summarizing the operating experience of domestic and foreign domestic sewage treatment devices, combined with scientific and technological achievements and engineering practice, a complete set of organic sewage treatment devices that can be buried is designed, which is a sewage treatment equipment mainly made of carbon steel anti-corrosion materials. The main purpose is to make domestic sewage and similar industrial organic sewage meet the discharge standards required by users after being treated by this equipment. This device is mainly used for the treatment of domestic sewage in residential communities (including villa communities), high-end hotels, hospitals, slaughterhouses, comprehensive office buildings, and various public buildings. The effluent quality treated by this device meets the national discharge standards. The entire set of equipment can be buried underground

2、 Characteristics of hospital sewage treatment equipment

4. Low noise, no odor, long service life.

3、 Overview of Hospital Sewage Treatment Equipment
With the development of China's economy and the advancement of urbanization, the shortage of water resources and the worsening of water pollution are becoming increasingly severe. The demand for sewage treatment and reuse is becoming more and more urgent. Traditional centralized sewage treatment faces prominent problems such as difficult sewage collection, high pipeline investment, large land occupation, and long construction cycle, which seriously restrict the sewage treatment rate and COD reduction. In this situation, decentralized sewage treatment integrated technology equipment has become a beneficial and necessary supplementary measure for centralized sewage treatment.

Existing decentralized sewage treatment equipment, some only use a single aerobic biochemical treatment process, which is not ideal for nitrogen and phosphorus removal; Some use a single aeration method, which results in high energy consumption; Some use plant treatment methods such as artificial wetlands, which occupy too much land and are affected by climate, resulting in unstable operation; Some devices have low integration and poor processing efficiency; In response to the above situation, through repeated practical exploration, we have independently developed a series of integrated technology equipment for the treatment of medium and low concentration dispersed organic wastewater with the aim of achieving standard discharge and resource recycling of sewage.

4、 Application areas:
Including residential communities, rural towns, scenic spots, highway service areas, airports, docks, industrial and mining enterprises, and other difficult to treat sewage. 3. Introduction to the installation system

5、 Working principle of hospital sewage treatment equipment
The core component of integrated sewage treatment equipment is membrane bioreactor (MBR),
It is a new sewage treatment technology that combines membrane separation technology with biotechnology.
Wastewater enters the MBR system. Zone A is a facultative zone, where fillers are placed and fully contacted with activated sludge. The O zone is an aerobic zone, where a membrane module is placed and PVDF membrane is used to trap activated sludge and large molecular organic matter, eliminating the need for a secondary sedimentation tank. The concentration of activated sludge is greatly increased, and hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, while difficult to degrade substances continuously react and degrade in the reactor. After further processing, the treated water can meet the discharge standards or be reused. In addition, the air transported to the MBR system is also a very important part of the treatment process. It can promote the circulation of fluids in the reactor, improve the degradation efficiency of activated sludge, and also cause friction between the hollow fiber membrane fibers to clean the membrane components. The process flow is as follows: collect sewage from places and areas where municipal sewage pipelines have not yet been constructed.

According to statistics, approximately 41% of electroplating factories in China use chemical methods to treat electroplating wastewater; In Japan, chemical laws account for about 85% of the total governance in the country. This method has the advantages of simple and reliable operation, low investment, ability to withstand large amounts of water and high concentration loads, and stable effects. It is suitable for sewage treatment of various types of electroplating enterprises. However, there is also a problem of secondary pollution of electroplating sludge, and enterprises generally entrust qualified units to dispose of it.

Activated carbon deodorization technology fully utilizes the physical properties of this adsorbent. The structure of activated carbon contains a large number of voids that cannot be observed by the naked eye, with a surface area ratio of 700-2300 square meters per gram, which has a good adsorption effect on odor gas pollution. Meanwhile, due to its use of only physical properties, it is convenient to use, has minimal side effects, and is relatively low in cost. However, the deodorizing effect of activated carbon is very limited; With the continuous development of material technology, new activated carbon fiber products have emerged. By using fibrous precursors and programmed carbonization activation treatment, they have the advantages of fast adsorption and desorption, low pressure loss, low powdering, and increased adsorption capacity. They also have certain alkali and acid resistance characteristics and can be processed into different forms of daily necessities; At present, the most common activated carbon deodorization technology is the "catalyst type", such as potassium permanganate activated carbon, potassium hydroxide activated carbon, etc. Essentially, it meets the combination of chemical and physical effects, thereby achieving better odor control effects.
