Slaughter Plant Waste Water Treatment Equipment
When used with domestic wastewater, MBR processes could produce effluent of high quality enough to be discharged to coastal, surface or brackish waterways or to be reclaimed for urban irrigation. Other advantages of MBRs over conventional processes include small footprint, easy retrofit and upgrade of old wastewater treatment plants.
1. Functions and parameters of main structures and equipment Front grid canal Because thewastewater discharged from the slaughterhouse is the main source ofwastewater, which contains a lot of blood, grease, wool, meat scraps, visceral debris, undigested food and feces, this design has carried out the enhanced pretreatment design for this part ofwastewater. The coarse grille was used to pretreat the waste water, such as wool, meat scraps, visceral debris, undigested food and feces, etc. Coarse grille intercepts impurity, can be used as fertilizer or feed, can also be used as fuel.
Main building:front grid canal Quantiy:1set Material:brick and concrete Outside size:L4000XW1200XH4000 Main equipment:grid Quantity:1set Design flow:500m3/d Grid bar distance:10mm Grid width:1000mm Power:0.75kW Back grid canal After the coarse grille intercepts, there are some minor impurities in thewastewater, which are removed by the fine grille.
Main building:back grid canal Quantiy:1set Material:brick and concrete Outside size:L4000XW1200XH4000 Main equipment:grid Quantity:1set Design flow:500m3/d Grid bar distance:10mm Grid width:1000mm Power:0.75kW Regulating sedimentation tank Because the characteristics of slaughteringwastewater discharge is that there are certain changes in water quality and quantity of water, the quantity of slaughtering varies with the seasons, festivals and time periods, and thewastewater discharge is concentrated. Direct entry into the biological treatment system will have a certain impact on the processing system. Therefore, a regulating tank is set up to regulate the water quality and quantity of wastewater. At the same time, a slag retaining plate is set up in the regulating pool to prevent floating scum from entering the subsequent treatment structure. In addition, the regulating tank is set to advection type and has the function of sedimentation, which can precipitate the precipitable matter in thewastewater and reduce the load of the subsequent treatment system. A sludge hopper is arranged at the back end of the regulating tank for storage of precipitated sludge, which is removed from time to time. Main structure: regulating sedimentation tank
Main building:Regulating sedimentation tank Quantity:1set Material:brick concrete Effective volume:530m3 Outside size:L16000XW9600XH4000 Effective water depth :3.5m Staying time:24h Main equipment:lifting pump QTY:1set(The backup pump is shared with the biochemical pool and is not installed on site) Flow:25m3/h Lift:15m Power:2.2kW Air floatation After the treatment of grille and settling tank, thewastewater also contains some oils, detritus and emulsified oil. The function of air flotation machine is to remove it. In order to ensure the effect of air floatation, coagulant and coagulant were added to the front end of the air floatation machine, so that the grease in thewastewater could be aggregated into larger particles to facilitate the adhesion of bubbles and take them to the surface of the water. The scum formed on the water surface is scraped into the slag trough by the scraper and then removed by the screw conveyor.

A/OBiochemical reaction cell After pretreatment, solid pollutants such as oil, wool, meat scraps, visceral debris, undigested food and feces were removed. Some macromolecular organic compounds such as protein and fat are also hydrolyzed to soluble small molecular organic compounds. Therefore, the main pollutants inwastewater are soluble small molecular organic matter. Because of the good biodegradability of the wastewater, the solid elastic packing with suspended filler was used to treat the wastewater. Main building: A- / O reaction pool number: three Material: brick concrete effective volume: 432 m3 shape dimensions: 1: L12000XW8000XH5000 effective water depth: 4.5m staying time:A pool 4h, 0 pool 16h
Main equipment: lift pump number: 2 units (one for backup pump and one for regulating pool) Flow rate: 25m / 3 / h head: 15m Power: 2.2kW main equipment: blower number: 2 units (one with one set) flow rate: 6.3 m3 / h wind pressure: 0.60 kgf- / cm2 power: 11kW effective water depth 4.5m
retention time: a pool of 4 h O pool 16h sedimentation basin The effect of the sedimentation tank is to separate the mixture containing activated sludge from a / o biochemical reactor, and the separated sludge part is returned to a / o reactor as reflux sludge for biochemical reaction. The other part of sludge is discharged to the sludge drying field as surplus sludge. A disinfectant contact tank was installed in the effluent part of the sedimentation tank, and then disinfectant was added to disinfect the effluent and then discharged to the biological stabilization pond.

The effluent of biological pond can be used for greening and washing ground. Main structure: biological pond number: 1 shape size: according to the level of the site effective depth of water: 2.8m
Sludge drying field The excess sludge from the sedimentation tank and the dross from the air floatation machine can be used as feed after drying due to the large amount of protein contained therein.
