在我国环境保护百花园里,各种污水处理技术犹如雨后春笋层出不穷。但是有的由于技术原因,不适合我国越来越严的环保要求,致使大量的污水处理工程出现升级改造,给中央和地方、以及用户造成的经济损失。还有的因运行费用过高,用户无法长期承受昂贵的运行费用,迫使污水处理处于停机或半停机状态。也有一些环保公司没有建设行政主管部门核发的设计和施工资质,承建的污水处理工程难以通过环保验收。另有极少用户重视力度不够,建成的污水处理工程使用率较低,没有起到保护环境的根本作用。建成投资少、运行费用低、安全、环保、节能增效的污水处理工程,不但有利于环境保护,而且也能改变用户对污水处理工作的重视。

信阳某厂家饲料生产、食品加工、种畜禽繁育等产业。集团年饲料生产能力1100多万吨,日宰杀家禽能力230多万只,年可生产畜禽种苗1亿多只。屠宰污水主要来自于圈栏冲洗、淋洗、屠宰及其它厂房地坪冲洗、烫毛、剖解、副食加工、洗油等工序所产生的污水,
屠宰污水有机物含量高,可生化性好其中高浓度有机质不易降解,处理难度较大,宰污水中的营养物主要是氮、磷,其中氮主要以有机物或铵盐形式存在,而磷主要以磷酸盐的形式存在。
屠宰污水一般呈红褐色,有难闻的腥臭味,其中含有大量的血污、油脂质、毛、肉屑、骨屑、内脏杂物、未消化的食物、粪便等污物,固体悬浮物含量高。
处理:排放的废水先后流经粗细两道格栅,主要去除较大悬浮物和漂浮物,防止污水提升泵等机械设备堵塞。然后流入隔油沉淀池,废水中含有泥沙等,这些可通过自然沉淀去除,沉淀的泥沙定期用污泥泵打入污泥浓缩罐。油脂则漂浮在水面,可以人工捞出回收处理。由于其废水水质水量波动较大,以确保后续处理效果和运行稳定性,在处理工艺流程中设置调节池,以均化水质水量。系统平稳运行。还可以通过调节池均化其本身的酸、碱度,以使废水的pH值满足后续处理工艺的要求。废水中含有的血污、油脂、油块等,通过混凝气浮得到有效的去除。
二级处理:对于屠宰废水中难降解、浓度较高的CODCr、BOD5,预处理过程中不能完全去除,故二级处理采用生化处理,本设计采用水解酸化-好氧生物处理技术。水解酸化池主要目的将大分子有机物分解成小分子有机物,以便在好氧过程中进一步得到去除。
三级处理:好氧处理后的出水,溢流到沉淀池中,沉淀后上清水进入消毒池,沉淀池中的污泥定期用泥浆泵打入污泥浓缩罐中。
工艺流程
屠宰场污水经格栅(网)去除污水中的毛、皮、浮渣和大颗粒悬浮物后自流入隔油池,去除大部分油脂和泥砂后进入调节池,经调节池调节水质水量后,并后续处理设施的正常运行。经过调节池的水经泵提升至平流式气浮沉淀一体机。先期去除水中悬浮物(ss),去除率达90%以上,出水进入一体化污水处理设备,一体化污水处理设备由(水解酸化池、二级接触氧化池、沉淀池组成),污水在水解酸化池
进行酸化处理,通过厌氧菌将大分子有机物转化成低分子有机物;经水解酸化池流入接触氧化池进行生化反应后再进入沉淀池,出水经过滤消毒达标排放
In China's environmental protection garden, various sewage treatment technologies are springing up like bamboo shoots after a spring rain. However, some technical reasons are not suitable for China's increasingly stringent environmental protection requirements, resulting in a large number of sewage treatment projects upgrading and upgrading, which will cause huge economic losses to the central and local governments and users. Also, because of the high cost of operation, the user can not bear the expensive operation cost for a long time, forcing the sewage treatment to be in the downtime or halt state. There are also some environmental protection companies that do not have the design and construction qualifications issued by the administrative departments, and the construction of the sewage treatment project is difficult to pass the environmental protection acceptance. In addition, few users do not pay much attention to the strength and the utilization rate of the completed sewage treatment works is low, and it does not play a fundamental role in protecting the environment. A sewage treatment project with less investment, low operation cost, safety, environmental protection, energy saving and efficiency is not only conducive to environmental protection, but also can change users' attention to sewage treatment.
Jining Tiantong Equipment Co., Ltd. is a company engaged in the production and sales integration of water treatment equipment. After continuous efforts, it has won a good market at home and abroad, and won the praise from customers. For many years, the company has always adhered to the concept of innovation, quality, service, dedication and gratitude. Adopt new ideas, strict quality, full range of service tracking, adhere to high quality products. Our main products: water treatment equipment, sewage treatment equipment, sewage treatment equipment, industrial equipment, agricultural sewage water equipment, water purification equipment, water equipment, steel hospital sewage water equipment, slaughterhouse wastewater equipment, food factory wastewater treatment equipment and other equipment, can be customized according to the requirements of professional water treatment equipment.
The industry of feed production, food processing, livestock and poultry breeding and other industries in Xinyang. The annual feed production capacity of the group is about 11000000 tons, and the daily slaughtering poultry capacity is about 2300000, and the annual production of more than 100 million animals and poultry seedlings can be produced. Mainly from the slaughter wastewater generated from pens, leaching, slaughtering and other plant floor washing, scalding, dissection, non-staple food processing, washing oil process wastewater,
The slaughterhouse wastewater has high organic content and good biodegradability. High concentration organic matter is not easy to degrade and difficult to deal with. The nutrients in slaughtering water are mainly nitrogen and phosphorus. Nitrogen mainly exists in the form of organic matter or ammonium salt, while phosphorus exists mainly in the form of phosphate.
General slaughter wastewater is red brown, with an unpleasant fishy smell, which contains a large amount of blood, oil quality, wool, meat, bone chips, visceral debris, undigested food, feces and other filth, high content of suspended solids.
First level treatment: the wastewater discharged through the two grille of coarse and thin, mainly removes larger suspended solids and floats, and prevents the blockage of mechanical equipment such as sewage lifting pumps. Then it flows into the oil separating sedimentation tank, which contains sediment and so on. These can be removed by natural precipitation, and the sediment deposited regularly is pumped into the sludge thickening tank by sludge pump. Oil is floating on the surface of the water and can be recovered artificially. Because the fluctuation of wastewater quality and water quantity is large, in order to ensure the subsequent treatment effect and operation stability, the regulation pool is set up in the process flow to homogenization the water quality and quantity. Ensure the smooth operation of the system. The acid and alkalinity of the tank can be homogenized by adjusting the pool to make the pH value of the wastewater meet the requirements of the subsequent treatment process. The wastewater containing blood, grease, oil and other pieces, by coagulation and air flotation is effectively removed.
Two stage treatment: for slaughtering wastewater, CODCr and BOD5 with high concentration and high concentration can not be completely removed during pretreatment. Therefore, two level biological treatment is adopted. This design adopts hydrolytic acidification aerobic biological treatment technology. The main purpose of the hydrolysis acidification pool is to decompose the macromolecule organic matter into small molecule organic matter so that it can be further removed during aerobic process.
Three stage treatment: after aerobic treatment, the effluent will overflow into the sedimentation tank. After precipitation, the upper water will enter the disinfection pond. The sludge in the sedimentation tank will be regularly pumped into the sludge thickening tank by mud pump.
Technological process
The slaughterhouse wastewater is removed by grid (net) to remove the hair, skin, scum and large particles suspended solids in the sewage, and then flows into the oil reservoir. After removing most of the grease and sand, it enters the regulating pool. After adjusting the water quality and quantity of the regulating pool, it ensures the normal operation of the subsequent treatment facilities. After the water pump to adjust pool horizontal flow type precipitation flotation machine. The removal of suspended solids (SS) in the water is more than 90%, and the effluent is integrated into the integrated sewage treatment equipment. The integrated sewage treatment equipment is composed of a hydrolytic acidification pond, a two stage contact oxidation pond and a sedimentation tank. The sewage is in the hydrolysis acidification pond.
After acidification, the macromolecular organic matter was transformed into low molecular weight organic matter through anaerobic bacteria. After hydrolysis and acidification pool was put into the contact oxidation tank, biochemical reaction and then entered the sedimentation tank. The effluent was filtered, sterilized and discharged.
