Small scale domestic sewage treatment equipment——Equipment Description

1The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. A new type of elastic three-dimensional packing material is used in the pool, with a large specific surface area and easy biofilm formation and detachment by microorganisms. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.

2The biochemical tank adopts the biological contact oxidation method, which has a relatively low volume load of fillers, and microorganisms are in their own oxidation stage, resulting in low sludge production and only requiring three months（90Discharge the mud once (using a manure truck to suction or dehydrate it into a mud cake and transport it outside).

3The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required.

Small scale domestic sewage treatment equipment——Characteristics of buried equipment:

1）HDWThe series of buried equipment can be fully installed underground (optional method), and the equipment above can be used for greening, increasing its aesthetic appeal,Saved land resources; Or place the equipment on the ground as required.

2）This equipment is a fully automatic biochemical treatment device, which operates safely and reliably without the need for professional personnel to be on duty. The effluent quality is stable and meets the standards for reuse.

3）Equipment maintenance is simple, with no sludge reflux operation, safe and convenient, no odor, and low noise.

4）The device has a long service life.HDWThe series buried municipal sewage treatment equipment is made of carbon steel anti-corrosion, glass fiber reinforced plastic and other materials, with high compressive strength, corrosion resistance, aging resistance and other excellent characteristics

5）Save resources, treat equipment with standard recycled water, which can be used for greening, flushing toilets, road surface washing, etc., and reuse resources

6）Wide processing range, It can treat domestic sewage and similar organic sewage, and has a wide range of applications.

Small scale domestic sewage treatment equipment——How to maintain cost-effective integrated buried sewage treatment equipment in daily life

Any device will experience accidents after long-term use, and the same applies to integrated sewage treatment equipment. Proper daily maintenance and upkeep are crucial for the longevity of the equipment. The integrated sewage treatment equipment must establish a regular maintenance system, and the main vulnerable parts are the fan and water pump. Below are the specific methods for daily maintenance and upkeep of the equipment.

Maintenance work must be carried out in accordance with the "Six Diligence Work Method", which includes diligent observation, listening, smelling, touching, hands-on, and garbage collection.

The specific content is:

1It is necessary to pay attention to the absence of large solid substances in the sewage entering the equipment. The garbage in the collection tank, grille, and slag conveyor should be regularly removed to avoid blocking the pipes and holes and damaging the water pump. Keep the water inlet unobstructed;

2The equipment manhole must be covered to prevent accidents or large solid objects from falling in;

3Wastewater entering the geographic sewage treatment equipmentPHThe value must be within6—9Between them, being acidic or alkaline can affect the normal growth of biofilms;

4The fan generally operates6It is necessary to change the oil every month or so to improve the service life of the fan;

5It is necessary to ensure that the air inlet of the fan is unobstructed.

6、 Work diligently. Make all necessary records and take action to solve problems.

Small scale domestic sewage treatment equipment——Equipment operation management

1Adjust the water pump and fan to normal state;

2Operate the program according to the design and frequently observe the water discharge situation.

3Generally, the control cabinet is placed in the automatic position and can be automatically controlled by the control cabinet. Usually, only one person is needed to conduct regular inspections and check the operation status every day.

Small scale domestic sewage treatment equipment——Common fault inspection

1Abnormal water discharge:

Check if the connecting pipes of the contact oxidation tank, sedimentation tank, disinfection tank, and sludge tank are blocked (usually caused by detached biofilm and damaged elastic three-dimensional packing).

2Uneven aeration in the contact oxidation tank:

Check if the outlet valve of the aeration fan is in the normal position and if the aeration head is damaged.

3The contact effect of biofilm is not significant

ACheck whether the aeration in the contact oxidation tank is uniform and whether the sludge in the secondary sedimentation tank is pumped to the tank;

BIf the above conditions are normal, add an appropriate amount of nutrients (such as white sugar, urea, etc.) to the pool.

4The effluent quality does not meet the standard

AExcessive water ingress;

BUneven aeration or prolonged shutdown of the contact oxidation tank (in which case the biofilm must be re cultured);

CExcessive sludge in the sedimentation tank (sludge must be removed);

DThe disinfection device is shut down and the effluent is not disinfected for a long time.

5Automatic control malfunction

ACheck if the power supply of the automatic control cabinet is normal;

BCheck if the supporting lifting pump and aeration fan are damaged (at this time, excessive current may cause the short-circuit switch to automatically disconnect).
