■ Product Introduction

Runhong Environmental Protection & Tongrun Environment TRHJ-WSZ- A/O integrated equipment is suitable for residential areas, rural towns, highway service areas, hotels, restaurants, hospitals, nursing homes, schools, shopping malls, ship terminals, stations, airports, industrial and mining enterprises, tourist attractions, villa, the scenic area sanitary sewage, medical sewage, aquaculture wastewater and simple processing of industrial wastewater.

Anaerobic/aerobic activated sludge process (A/O) is a biological wastewater treatment process, which consists of anaerobic and aerobic parts. After entering the anaerobic tank, the sewage is mixed with the return sludge. In this process, polyphosphate bacteria in activated sludge absorb a large amount of BOD5 in sewage, and release phosphorus in sludge into the mixed solution in the form of orthophosphate. After the mixed solution enters the aerobic tank, the organic matter is oxidized and decomposed, and polyphosphate bacteria absorb orthophosphate in the mixed solution into the sludge. Because phosphorus accumulating bacteria absorb more phosphorus under aerobic conditions than phosphorus released under anaerobic conditions, the sewage undergoes "anaerobic-aerobic" alternation and sludge separation in the secondary sedimentation tank, and finally achieves the goal of phosphorus removal.

Based on the principle of customer first, the design, production and installation of our products are from the following aspects: practicality, high quality, beauty, high cost performance, simple operation and convenient maintenance.


■ Product Advantage:

Integrated wastewater treatment equipment

(1)Integrated sewage treatment equipment is made of carbon steel anticorrosion treatment or stainless steel components, which are spliced and combined on site. It is light in weight, easy to transport and convenient to install;

(2)Adopt FRP, carbon steel and stainless steel anti-corrosion structure, which has excellent characteristics such as corrosion resistance and anti-aging, and its service life is more than 30 years;

(3)Placed below the ground surface, without building houses, heating and heat preservation, the system integration is realized to the maximum extent, and the occupied area is reduced;

(4)The integrated sewage treatment equipment can be designed to be fully buried, without pollution, noise and odor, and reduce secondary pollution;

(5)Integrated sewage treatment equipment is not limited by the amount of sewage, which is flexible and can be used singly or in combination;

(6)The whole equipment processing system is equipped with PLC automatic electrical control system and equipment fault alarm system, which is safe and reliable in operation and low in management cost;

(7)The whole equipment processing system is equipped with PLC automatic electrical control system and equipment fault alarm system, which is safe and reliable in operation and low in management cost;


■ Technology Introduction

The design of A/O integrated sewage treatment equipment is mainly to treat domestic sewage and similar industrial organic sewage, and its main treatment means is contact oxidation method, which is a mature biochemical treatment technology at present. It consists of six parts: adjustment tank, hydrolysis acidification tank, contact oxidation tank, secondary sedimentation tank, disinfection tank and sludge digestion tank.

The process flow of A/O integrated equipment is as follows:

■ Function Introduction

The integrated sewage treatment equipment with A/O process as the main process has the functions of reducing organic pollutants, removing phosphorus and nitrogen, has no sludge bulking problem, and is relatively simple in operation and management. Due to the large specific surface area of packing, good oxidation conditions in the tank, high biosolids per unit volume in the biological contact oxidation tank, sludge backflow and high concentration of activated sludge in the reaction tank, the activated sludge process was combined. Has a high volume load. Because of a large amount of biosolids, when the organic volume load is high, the F/M ratio can be kept at a certain level, so the sludge yield can be equal to or lower than that of activated sludge process. This process has the advantages of simple operation, low operation cost, good treatment effect and stable operation. It is a mature domestic sewage treatment process, which can effectively ensure that the sewage discharge reaches the standard.

It is difficult to repair and maintain the A/O integrated sewage treatment equipment because it is buried. Therefore, its maintenance-free property is considered in the design, and the whole equipment structure is reasonable and reliable. At the same time, it is also considered that even if some faults occur, it can enter the equipment through various inspection holes.

All facilities of A/O integrated sewage treatment equipment are set in several boxes, and the main equipment is made of steel structure, which is deeply anticorrosive. After the internal and external surfaces are treated by mechanical derusting, the internal and external surfaces are treated by epoxy coal tar pitch, and the anticorrosion life can generally reach more than 10 years.
