1、 Overview of Slaughter Wastewater Treatment Equipment

Due to the continuous improvement of people's living standards, there has been a significant increase in both the quantity and freshness of food. Nowadays, not only are cities a consumer of poultry meat products such as pork and lamb, but rural areas also have a high demand. Due to the dispersion of regions, many are individual businesses, and driven by profit, many people directly discharge wastewater without treating it. It has had a significant impact on the surrounding environment. The ground flushing water containing blood and animal manure discharged from the slaughterhouse, the high-temperature water containing a large amount of pig hair discharged during scalding, and the wastewater from cleaning, dismantling, and internal organ cleaning after slaughter. Wastewater generally presents a reddish brown color with an unpleasant fishy odor, containing a large amount of blood, oil, meat, bone and other pollutants. It has a high content of suspended solids and organic pollution. The COD value of the main component of wastewater is generally around 1500mg/L, and it has good biodegradability. In response to these characteristics, Dongguan Gaoda Environmental Protection Technology Co., Ltd. has developed and produced an integrated device for treating slaughter wastewater, which is a high-tech environmental protection product that purifies the wastewater generated during the slaughter process to ensure that the effluent quality meets national discharge standards.

2、 Introduction to Common Process Flow of Integrated Equipment for Slaughter Wastewater Treatment

Therefore, a grille should be used to intercept it first to ensure the normal operation of subsequent equipment, as slaughter wastewater contains large molecular organic compounds such as blood stains and oil, which are difficult to degrade when directly entering aerobic treatment. In order to reduce the load on subsequent treatment facilities, it is considered to set up an air flotation device to remove oil and reduce the concentration of SS. Set up a large regulating tank to regulate water quality and quantity to ensure the normal operation of the entire facility and reduce the impact load on subsequent facilities. Wastewater is collected in the regulating tank and then pumped into the subsequent treatment facility through a pump to further degrade it into small molecule substances, preparing for subsequent aerobic biochemistry. Considering the excessive ammonia nitrogen and total phosphorus in the wastewater, the facility operates in an alternating aerobic anoxic environment to achieve the effect of nitrification denitrification and phosphorus removal. Here, a hydrolysis acidification tank is set up to reflux the effluent from the subsequent aerobic treatment to the hydrolysis acidification tank. After being treated by various biochemical treatment facilities in the front-end, the organic pollution load is greatly degraded. Then set up a coagulation sedimentation tank and add targeted chemicals. The effluent from the sedimentation tank enters the disinfection tank, and finally meets the discharge standards.

3、 Technical types of slaughter wastewater treatment equipment

1. Physical processing; Screening, skimming, adjustment, precipitation, air flotation, filtration, microfiltration, reverse osmosis, and activated carbon adsorption.

2. Biochemical treatment; Aerobic, anaerobic, facultative, etc.

3. Physical and chemical processing; Coagulation, adsorption, membrane separation, etc.

4、 Reclaimed water system for slaughter wastewater treatment

Physical and chemical disinfection processes can be used, as follows:;

Source Water --->Regulating Tank --->Filtration Tank --->Disinfection Tank --->Storage Tank --->Discharge When using residential sewage as the source of reclaimed water, the biochemical+disinfection process can be used, as follows: Source Water --->Hydraulic Screen --->Regulating Tank --->Biochemical Tank --->Filtration Tank --->Disinfection Tank --->Storage Tank --->Discharge The above process facilities can be designed as above ground or underground structures according to the specific situation on site.

5、 What should I pay attention to when purchasing integrated equipment for slaughter wastewater?

1. Suppliers can be requested to provide successful cases or visit the site to observe the effects

Everything should be based on facts. No matter how the supplier who provides you with the equipment introduces its superior performance, you should ask the supplier to provide previous successful cases and then send someone to inspect its on-site sewage treatment effect. Although it may delay some time, it is crucial to test the professionalism of the merchants you cooperate with and whether the follow-up services can be timely and in place.

Gaoda Environmental Protection Technology Co., Ltd. has a large number of cases and has served Fortune 500 companies, schools, and more. Its service area covers the whole country. If you need underground integrated sewage treatment equipment, please feel free to inquire or visit the factory to view engineering cases. We will arrange for you at any time and provide you with satisfactory results display.

2. Distinguish between equipment quality and size

The quality and size of equipment are usually determined by discharge standards, types of treated sewage, and water volume. Currently, the most commonly used underground integrated sewage treatment equipment is made of carbon steel material.

3. Agree on the execution of water discharge standards

Many units fail to specify the sewage treatment standards in the contract when purchasing buried integrated sewage treatment equipment, which can lead to disputes in the future when environmental protection requirements are raised. Because emission standards have a certain impact on acceptance and pricing, there are differences in the cost of sewage treatment. There are several types of emission standards:

Pollutant Discharge Standards for Urban Sewage Treatment Plants (GB18918-2002)

Integrated Wastewater Discharge Standard (GB8978-96)

Sanitary Standards for Drinking Water in the People's Republic of China GB5749-2006

Surface Water Environmental Quality Standards (GB3838-2002)

Design Specification for Water Supply and Drainage in Residential Areas (CECS57-94)

Code for Design of Building Water Supply and Drainage (GB50015-2003)

Design Code for Water Supply and Drainage Engineering (GBJ15-88)

Design Code for Outdoor Drainage (GBJ14-91)

Technical Conditions for Manufacturing Water Treatment Equipment (JB2932-86)

4. Thoroughly understand and communicate the pre -, mid -, and post installation, debugging, and acceptance work in a timely manner

After the equipment purchase process is completed, users need to communicate and contact the manufacturer of the buried integrated sewage treatment equipment more often, and prepare the equipment burial work in advance according to the drawings provided by the manufacturer, such as water and electricity, pipelines, and equipment pit burial three-way and one leveling issues. If the preliminary work is not operated according to the drawings, it will increase unnecessary costs for both parties. Regarding the coordination of equipment unloading, installation, and debugging, the manufacturer provides guidance and training on equipment maintenance and common issues. The necessary materials and acceptance processes for subsequent acceptance should be understood in advance or asked for the manufacturer's cooperation in providing them.
