Sewage treatment equipment for small meat product factories——The functions of each component:

1）Grille Grilles are mainly used to intercept large floating objects in sewage, ensuring the normal operation of subsequent treatment structures and effectively reducing treatment loads, providing guarantees for the long-term normal operation of the system. One artificial grille is used for the grille. The artificial grille is made of stainless steel in a mesh shape, with gaps between the bars5-10mmThe grille adopts1Only. 2）The regulating pool is mainly used to regulate the quality and quantity of wastewater discharged from stations and living areas. To prevent particles from settling in the regulating tank, perforated aeration pipes are installed at the bottom of the tank. High, medium, and low level controllers and water pumps are installed in the tank, and overflow holes and overflow discharge outlets are provided at the upper opening of the tank. Submersible sewage pumps are installed in the water pump pit.

This type of filler has the advantages of not being easily blocked, being lightweight, having a large specific surface area, and stable treatment effect. It is also easy to maintain and replace, with a residence time of≥3.5Hour. （2）OGrade biochemical poolA/OThe packing material for the biochemical tank adopts a columnar biological carrier packing set inside the tank, which has a large specific surface area and is the same as general biological packing materials16～20times(Same unit volume)Therefore, maintaining a high biomass in the pool achieves the goal of high-speed removal of organic pollutants. The aeration equipment adopts a blower and a microporous aerator, and the utilization rate of oxygen is30Above, it effectively saves operating costs. dwell time≥7Hour by hour, the ratio of air to water is12：1左右。 （3）Sedimentation tank Sewage treatmentOAfter treatment in the biochemical tank, the water contains a large amount of suspended solids (biofilm shedding). In order to improve the effluent qualitySSTo meet the emission standards, a vertical flow sedimentation tank is used for solid-liquid separation. Setting of sedimentation tank1Seat, surface load is1.0m3/m2• hrThe sludge in the sedimentation tank is lifted to the sludge tank by gas lifting equipment, and a portion of the sludge can be lifted to the sludge tank according to the actual water qualityAPerform sludge reflux in the biochemical tank to increaseOThe concentration of sludge in the biochemical tank is increased to improve the removal efficiency. （4）Disinfection pool The contact time of the disinfection pool is30minute Chlorine dioxide disinfection is used for disinfection. The dosage is4－6mg/LAfter biochemical treatment and sedimentation, the treated water is then disinfected. （5）Sludge tank Effective capacity of sludge tank8m3,The sludge from the sedimentation tank is lifted by air to the sludge tank for normal temperature digestion. The supernatant from the sludge tank flows back to the contact oxidation tank for further treatment, and there is very little residual sludge after digestion. The cleaning method can be achieved by inserting a suction truck from the inspection hole of the sludge tank into the bottom of the sludge for suction and transportation. （6）Fan room, fan The fan is located in the fan room and equipped with a muffler, so the noise during operation meets environmental protection requirements. （7）Lift pump The lifting pump adopts anti clogging and tear typeWQSubmersible sewage pump, with strong sludge discharge capacity, no blockage, and can effectively pass through the diameter10mmSolid particles. There are two lift pumps for the regulating tank, which are divided into working pump and standby pump. The start of the pump is controlled by the floating ball of the regulating tank. The floating ball switch is composed of a fully sealed glass structure, with the external foam plastic as the carrier. The floating ball is divided into three according to the liquid level of the regulating tank, and is controlled by the control cabinet. （8）Fan The fan adopts the product produced by PepsiCo, with the model ofHC-25ISThe fan has low noise and long service life. In the system process, fans are used for air blowing and aeration24Exchange usage within hours. When the regulating pool water pump stops, the fan interval2Hourly aeration0.5Hour by hour, with each fan running24Automatically switch once every hour, and this process is controlled by the control cabinet.

Integrated sewage treatment equipment biological contact oxidation method andMBRComparison of Craftsmanship

Types of commonly used processes

There are mainly two commonly used processes for treating domestic sewage nowadays, one is the contact oxidation method for domestic useA/OLaw, the other isMBRMembrane biological method.

Characteristics of two processing techniques

Biological contact oxidation method:

Advantages:

The process has been running for many years and runs more smoothly. After debugging and normal water output, it can ensure long-term stable operation.

Operation management is relatively simple and does not require backwashing. Only a few months later, a portion of the sludge in the sludge tank can be extracted.

The requirements for the quality of operators are relatively low. Without power outages and ensuring stable water inflow, it is only necessary to monitor whether the equipment is working properly every day.

The overall investment of the equipment is relatively even, without expensive individual core components, and the operating costs are relatively low.

Disadvantages:
1Compared toMBRThe effluent quality of membrane bioreactor may be poor, and there may be some suspended solids being carried out.

MBRMembrane biological method:

Advantages:

After debugging, the effluent quality is superior, higher than the first levelAThe emission requirements.

Disadvantages:

MBRThe membrane is prone to blockage of the outlet by sludge in sewage, resulting in difficulty in water discharge. The usual measure taken in the early stage is to use a chemical agent for online cleaning. When the effect is not ideal, the membrane components need to be removed from the system for separate cleaning, which requires high cleaning conditions. In the later stage, some membrane components need to be replaced irregularly to ensure normal water discharge.

The quality requirements for operators in the process are relatively high, and they must have a certain professional foundation, understand the process flow, be clear about the water output, and the pressure difference of membrane components for membrane cleaning needs.

MBRThe membrane is the core component of the entire process, which is expensive and requires high maintenance and replacement costs.
