How to design a sewage treatment plan for a small brewery? For some distilleries, we all know that they produce a certain amount of wastewater during the brewing process. Therefore, wastewater treatment has become a headache for these distilleries, especially for some small distilleries. If wastewater treatment is required, there are two issues: financial issues and professional issues. For small distilleries, integrated wastewater treatment equipment can be chosen for wastewater treatment. So how to choose sewage treatment equipment for small breweries? What are its advantages and disadvantages? Let's take a closer look below.

Our company's brewery's sewage treatment equipment has a novel structure and is easy to operate. It uses water cooling to liquefy high-temperature water vapor, achieving the recycling and utilization of water resources. When high-temperature water vapor liquefies, a large amount of heat is released, heating the water inside the water tank body to achieve the utilization of heat in the high-temperature water vapor. The design of the fixing plate facilitates the fixation of the water tank body, and the design of the heat dissipation fin improves the heat dissipation efficiency, Through the design of liquid level switches and solenoid valves, automated drainage has high practicality, greatly improving the functionality of this brewing wastewater recycling device. Its use effect and efficiency are suitable for widespread promotion. 

Design ideas for wastewater treatment equipment in breweries

(1) First level processing:

The discharged wastewater flows through two grids, one coarse and the other fine, mainly to remove large suspended solids and floating objects, and to prevent mechanical equipment such as sewage lifting pumps from clogging. Then it flows into the oil separation sedimentation tank, and the wastewater contains sediment, which can be removed through natural sedimentation. The sediment is regularly pumped into the sludge concentration tank by a sludge pump. The oil floats on the water surface and can be manually retrieved for recycling. Due to significant fluctuations in the quality and quantity of wastewater, in order to ensure the subsequent treatment effect and operational stability, a regulating tank is set up in the treatment process to homogenize the water quality and quantity* The system runs smoothly. It is also possible to homogenize the acidity and alkalinity of the wastewater by adjusting the pool to meet the requirements of subsequent treatment processes. The blood, grease, oil lumps, etc. contained in wastewater are effectively removed through coagulation and air flotation.

(2) Secondary treatment: 

COD and BOD which are difficult to degrade and have high concentration in slaughterhouse wastewater cannot be removed during pretreatment, so Secondary treatment adopts biochemical treatment. Hydrolysis acidification aerobic biological treatment technology is adopted in this design. The main purpose of the hydrolysis acidification tank is to decompose large molecules into small molecules for further removal during aerobic processes. 

(3) Third level processing:

The effluent after aerobic treatment overflows into the sedimentation tank, and after sedimentation, clean water enters the disinfection tank. The sludge in the sedimentation tank is regularly pumped into the sludge concentration tank by a mud pump.

Working principle of wastewater treatment equipment in breweries:

The brewery sewage treatment equipment is designed specifically for the treatment of domestic sewage and similar industrial wastewater. The main treatment method adopts a relatively mature biochemical treatment technology, the A/O process (Anoxic Oxic), and the biological contact oxygen process is a sewage treatment process between the activated sludge method and the biofilm method.

The integrated sewage treatment equipment is equipped with fillers, with some microorganisms fixed on the surface of the fillers in the form of biofilms and some suspended in flocs, thus possessing the characteristics of activated sludge method and flocculant.

Sewage treatment equipment saves land, increases filling rate, increases capacity and effectiveness of treatment, and adds new structural process description: AO water treatment process (Anoxic Oxic) utilizes different types of microorganisms to remove impurities from washing wastewater, with different impacts at different stages of the treatment process.

In the absence of oxygen in segment A, facultative and anaerobic microorganisms grow, facultative bacteria on the biological filler use their own metabolism to hydrolyze large molecules in the wastewater into small molecules, which is beneficial for the subsequent aerobic biochemical part.

In the aerobic phase O, due to the use of underwater aerators to flush enough oxygen into the water, good organisms reproduce on the filler and metabolize the * * degradable * * substances in the water into harmless inorganic substances. The dead biofilm regularly returns to the anoxic part of the sedimentation tank, and the sludge tank undergoes denitrification, digestion, and decomposition by anaerobic bacteria. There is no occurrence of sludge bulking, and the equipment operation mode is fully automatic/manual. 

Advantages of sewage treatment equipment in small breweries

1. Compact, small in size, with a small footprint, a buried structure, movable, convenient for greening, and no breeding of mosquitoes and flies. 

2. * * High pollutant removal rate and stable effluent quality. 

3. Simple operation, convenient construction, special maintenance, and good self-protection performance of the equipment. 

4. The water treatment performance is good and meets the discharge standard requirements. 

5. Living equipment can be flexibly configured based on the quality of raw water, making it widely applicable.

6. Equipped with corrosion resistance, * * and other characteristics, with a service life of over 50 years. 

Process of Sewage Treatment Equipment in Small Distillery

1. Primary sedimentation tank 

The sewage in the regulating tank is pumped into the primary sedimentation tank by the sewage pump, and some larger particles of pollutants are precipitated. Sludge lift sludge tank.

2. Contact oxidation tank:

The sewage in the first stage sedimentation tank flows into the contact oxidation tank for biochemical treatment. The contact oxidation tank is divided into two stages, with a total retention time of 7 hours. The filling material is novel elastic, easy to form film, and not clogged. The air water ratio in the oxidation tank is around 20:1. Domestic sewage treatment equipment process

3. Secondary sedimentation tank: 

The biochemical sewage flows to the secondary sedimentation tank, which adopts the vertical flow sedimentation, with the rising flow rate of 0.1-0.15mm/s, and the sludge lifts the sewage.

4. Disinfection pool and disinfection device: 

The disinfection pool follows the specifications of "TJ14-74", and the water stays here for 45 minutes. Disinfection adopts a solid chlorine tablet contact dissolution disinfection method, and the disinfection device can continuously change the dosage according to the size of the water output, achieving the goal of adding more medicine to more water output and less water output.

5. Fan room and fan:

The fan room is located above the clean water tank. The fan adopts two three blade Roots fans, which can automatically operate alternately and can be adjusted for 0-12 hours. The operating life of a single fan is about 30000 hours, and there is an air inlet, so the noise during operation is low. 

Working principle of wastewater treatment equipment in breweries:

The sewage treatment equipment of the brewery is a membrane bioreactor technology adopted by our company. The quality of the system's effluent is different from traditional sewage treatment equipment in all aspects, so this equipment can be used as a device for reclaimed water reuse. The removal of pollutants and nitrogen mainly depends on the AO biological treatment process in the equipment. The working principle is in the first stage. Due to the high concentration of * * substances in the sewage, the microorganisms are in a state of hypoxia. At this time, the microorganisms are facultative microorganisms. Therefore, the first stage tank not only has a certain * * substance removal function, reduces the subsequent load of the aerobic tank, and reduces the * * substance concentration, but there is still a quantitative * * substance and higher NH3-N.
