The domestic sewage treatment integrated machine is based on summarizing the domestic and foreign domestic sewage treatment equipment operating experience, combined with its own scientific research results and engineering practice, designed an integrated organic wastewater treatment device, which integrates the removal of BOD5, COD, NH3 -N in one, it has the advantages of stable and reliable technical performance, good treatment effect, low investment, automatic operation, convenient maintenance and operation, no land occupation, no need to build a house, no need for heating and heat preservation, etc. The integrated domestic sewage treatment machine can be set to be buried, and flowers and grass can be planted on the ground without affecting the surrounding environment.
1. Structure and characteristics
The design of the integrated domestic sewage treatment machine is mainly for the treatment of domestic sewage. The main treatment method is the contact oxidation method, which is a relatively mature biochemical treatment technology. The water quality design parameters are also designed and calculated according to the general domestic sewage water quality.
It consists of six parts: (1) anoxic tank (2) contact oxidation tank (3) secondary sedimentation tank (4) disinfection tank, disinfection device (5) sludge tank (6) fan room.
2. Working principle
The two-stage biological contact oxidation treatment process adopts the plug-flow biological contact oxidation, and its treatment effect is better than that of the complete mixing type or the two-stage series complete mixing type biological contact oxidation tank. Compared with the activated sludge tank, the volume is smaller, the adaptability to water quality is strong, the impact load resistance is good, the water quality of the effluent is stable, and there is no sludge bulking. The tank adopts a new type of elastic three-dimensional filler, which has a large specific surface area, and microorganisms are easy to hang on the film and remove the film. Under the same organic matter load condition, the removal rate of organic matter is high, and the solubility of oxygen in the air in water can be improved.
The biochemical tank adopts the biological contact oxidation method, the volume load of the filler is relatively low, the microorganisms are in the self-oxidation stage, and the amount of mud produced is small. Mud cake outbound).
3. Scope of application
1. Hotels, restaurants, nursing homes, hospitals;
2. Residential quarters, villages, market towns;
3. Stations, airports, seaports, ships;
4. Factories, mines, ministries, tourist spots, scenic spots;
5. Various industrial organic wastewaters similar to domestic sewage.
4. Installation and use
1. Foundation: If the integrated domestic sewage treatment machine is placed above the floor, it is only necessary to prepare a concrete floor with the same shape as the equipment as the foundation. The foundation pressure must be greater than 4T/m2, and it is also required to be level and flat.
If the equipment is buried below the floor, the elevation of the foundation must be less than or equal to the elevation of the equipment and to ensure that there is no water accumulation when it rains.
2. Installation: According to the installation drawing, each box is in place in turn. The position and direction of the box can not be misplaced, the distance between each other must be accurate, and the pipes should be connected well.
