The role of central control is one word: look.

Show it to yourself, show it to others.

What to show yourself? All historical data can be seen in the central control, as the name suggests, and can be the sewage plant all links, each parameter together to control and record, if the water quality exceeds the standard, failure, you can trace is the best problem, this is to show yourself.

So what to show to others? The sewage plant should be a state-controlled unit, naturally there will be a variety of higher departments to check, they will come to see the operation of the sewage plant, look at the account records, at this time to see the central control, they don't like the sewage plant to take out a box of historical records, just a little central control mouse, you can see everything, this is for others to see.

The sewage treatment system comprises a water collection basin, a coarse grid, a pump room, a fine grid, an aeration sink sand tank, an oxidation ditch, a water distribution well, a secondary sedimentation tank, a disinfection tank, the collection basin, a coarse grid, a pump room, a fine grid, an aeration grit tank, an oxidation ditch, a water distribution well, a secondary sedimentation tank, a disinfection tank are sequentially connected through a pipeline, the oxidation ditch is also provided with a sludge treatment branch, and the sludge treatment branch comprises a sludge return pipeline, a sludge thickening tank, a sludge dewatering workshop, Described oxidation communication sludge return pipeline is connected with the input end of sludge thickening tank, and the output end of described sludge thickening tank is connected with sludge dewatering workshop by pipeline. This system can effectively treat the sewage, so that the sewage discharge meets the national discharge standards and will not affect the land, rivers, etc.

The sewage treatment system generally includes the following main facilities: sewage collection system, sewage primary treatment system, coarse or eggplant water biochemical treatment system, sludge treatment system, sewage discharge system and automatic control system.

The most common integrated sewage treatment equipment consists of four parts: anoxic tank, aerobic tank, sedimentation tank, and disinfection tank.

The anoxic tank is mainly set up for denitrification treatment, and it is also the first step of the AO process, if the equipment is AAO process, an anaerobic tank will be added to the front end of the anoxic tank to achieve the effect of strengthening phosphorus removal. The front end is usually equipped with a grille to intercept large floating debris and suspended particles.

The aerobic pond mainly plays the role of nitrification, explains the organic matter in the sewage, and makes it stable and harmless. Filler or activated sludge will be placed in the tank. In some cases, some MBR modules are also placed in this pool.

The sedimentation tank is to remove suspended solids in the water by using the effect of natural sedimentation or coagulation sedimentation. Generally, it is called the primary sedimentation tank before biochemistry, and the sedimented sludge has more inorganic components, and the moisture content of the sludge is lower than that of the sludge in the second sedimentation tank. The sedimentation tank located after biochemistry is generally called the modified secondary sedimentation tank, which is mostly organic sludge with high sludge moisture content.

As the name suggests, the disinfection tank is to disinfect the sewage to remove bacteria and viruses in the sewage, and the common disinfection methods are chlorine, sodium hypochlorite, ozone, ultraviolet, etc.

1.Grid grit remover tank: isolate the large debris and floating objects in the incoming water, and at the same time make the larger particles in the incoming water settle down here. Simple grids or mechanical grids can be selected according to water quality conditions. Screening slag and grit are cleaned regularly, and handed over to the municipal government for unified treatment after disinfection.

2.Regulating Tank: Regulate the amount of water and balance the water quality. Improve the impact load resistance of the system.

3.Integrated sewage treatment equipment: the main process is a biochemical process, with built-in sedimentation and sludge return system.

The shell is made of mechanically wound FRP tank body, which is a buried design. The core part of the equipment is the biological contact oxidation section, which adopts the immobilized living cell process and adds an external high-efficiency aeration system to dissolve the organic matter in the water through the life metabolism of aerobic cells, so as to achieve the purpose of purifying water quality. The equipment is particularly suitable for the purification process of domestic wastewater.

4.Sand filter ecological pool: It can be used as an effective supplement to the integrated sewage treatment equipment and carry out advanced treatment of the effluent of the integrated sewage treatment equipment.

The treatment system is a single-level manifestation of the constructed wetland ecosystem. Through the adsorption of substrate, the digestion of microorganisms and the absorption of plants, the effluent water quality is stable to meet the design requirements.

5.Equipment room: There are two blower aerators and PLC automatic control equipment.

The blower aerator is one for use and one for standby, and it is switched to run. All equipment in the sewage treatment station is automatically controlled and switched through PLC control equipment, and automatic protection is carried out for overcurrent, phase loss, overvoltage, undervoltage and other faults.

The name of the profession is "grey water system".

Reclaimed water refers to the water that can be used beneficially after proper treatment to reach certain water quality indicators, meet certain use requirements, and be used beneficially. Compared with seawater desalination and cross-basin water transfer, reclaimed water has obvious advantages. From an economic point of view, the cost of reclaimed water is the lowest, about 1 3 yuan tonnes, while the cost of seawater desalination is about 5 7 yuan tonnes, and the cost of inter-basin water transfer is about 5 20 yuan tonnes.

From the perspective of environmental protection, sewage recycling helps to improve the ecological environment and realize a virtuous cycle of water ecology.

Our company has installed a reclaimed water treatment system, which has been put into use at present, with good results and good water-saving effects. After the sewage is treated, it is good to flush the toilet and water the flowers.

Sewage treatment (wastewater treatment): The process of purifying sewage in order to make it meet the water quality requirements for draining a body of water or reusing it. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering and other fields, and is increasingly entering the daily life of ordinary people.

Suitable for residential areas, detached villas, health centers, hotels, hotels, attractions, stations, marinas, airports, shopping malls, nursing homes, schools, factories and mines. Domestic sewage and some industrial organic wastewater discharge points. Intelligent control does not require personnel protection, stability and safety maintenance.

Basement drainage is very difficult to solve for many people, first of all, there is no sewage pipe in the basement, resulting in the sewage can not be discharged normally, of course, many people will also say that the basement is open to reserve a water pit, and the sewage can flow directly into the pit and be discharged directly, of course, the pit must be installed with a submersible sewage pump.

In fact, this method can also solve the basement drainage, but if you want to talk about the basement transformation into a leisure and entertainment space, it is definitely not recommended, the drainage method of the pond + submersible sewage pump is, in the final analysis, the sewage flows directly into the pit, even if the pit is placed on the manhole cover, it is still impossible to get rid of the peculiar smell, and the float control used by the submersible sewage pump, the drainage time will be easy to be blocked by impurities, and the maintenance cycle of the pond will be very long, and someone needs to maintain it regularly, and it is too troublesome in all aspects.

In fact, the current household drainage method will abandon the submersible sewage pump + pond and use the integrated sewage lifting device to solve the problem.

So what is an integrated sewage lifting device?

What about the integrated sewage lifting device? It is to solve the problem of sewage discharge in places without gravity flow, that is, to solve the problem of no sewer in the basement area, and to help us lift the sewage generated in the basement to the nearby gravity flow pipe network.

So what are the advantages compared with submersible sewage pump + pond pit?

First of all, it must be easy to install, compared with the submersible pump, the installation is more diversified, the submersible pump must be installed inside the water accumulation pit, and the integrated sewage lifting device is not too dependent on the installation in the pit, that is, it can be installed on the ground or in the wall.

Secondly, there is no peculiar smell, and the integrated sewage lifting device will be equipped with ventilation holes, which can be installed separately to say that the peculiar smell in the sewage can be directly discharged outdoors, and the fully sealed box does not need to worry about sewage overflow.

Again, of course, there is no need for maintenance, of course, this is only for the external sewage lifter, in general, the external equipment will be equipped with a backwashing device, which can save us the trouble of daily maintenance.

Last but not least, the equipment is equipped with a powerful cutter and a one-way check valve to prevent both of these situations.

Therefore, in contrast, it is more recommended to use an integrated sewage lifting device for basement drainage.

The integrated sewage treatment equipment is a device that integrates the primary sedimentation tank, the I and II contact oxidation tanks, the sedimentation tank and the sludge tank, and carries out hail and air aeration in the I and II contact oxidation tanks, so that the contact oxidation method and the activated sludge method are effectively combined, saving the cumbersome design of the sewage treatment process and infrastructure construction. Features and advantages similar to Eco sewage treatment equipment, such as:

1. It can bear a strong impact force and can continue to oxidize for more than 6 hours.

2. It can treat the wastewater of the laboratory, the production wastewater of enterprises, the wastewater of research and development of colleges and universities, etc., with strong comprehensiveness and wide practicability.

3. The effluent quality is stable, and there will be no secondary pollution such as waste residue and waste gas.

4. It is easy to complete automatic control, can realize remote monitoring, simple management operation and high work efficiency.

5. The source bending key equipment can be connected to the car to make a mobile integrated sewage treatment equipment.
