Embodiment 1

[0052] This embodiment is applied to ten thousand pig farms. According to the combined process route of the present invention, a water collection tank, a hydrolysis acidification tank, an EGSB anaerobic reactor, a regulating tank, an SBR reactor and a biological pond are respectively constructed. The water volume of the pig farm is 150m 3 / d, the raw water quality is COD8000~12000mg / L, NH 3 -N300~1200mg / L, TP40~100mg / L.

[0053] Using this process to treat wastewater, the steps are:

[0054] A. After the wastewater to be treated is collected by the wastewater pipe network, it is intercepted by the grid to remove larger particles and suspended solids in the wastewater.

[0055] B. Secondly, the waste water enters the sump, and the sump plays the role of collecting, storing and balancing the water quality and quantity of the waste water, and adjusting the pH of the water quality. Adjust the pH of the wastewater to between 6 and 9. When the pH value of the water is lower than...

Embodiment 2

[0067] This embodiment is applied to the waste water in the expressway service area, and its water volume is 80m 3 / d, the raw water quality is COD1500mg / L, NH 3 -N130mg / L, TP30mg / L. Its steps are identical with embodiment 1.

[0068] Experimental results:

[0069] After the raw water passes through the grid to remove larger particles and suspended solids in the wastewater, it enters the hydrolysis acidification tank to convert macromolecular and refractory organic pollutants into small molecular organic matter, and the effluent enters the EGSB anaerobic reactor, most of the easily degradable organic matter The effluent from the EGSB anaerobic reactor enters the SBR reactor, and through the action of microbial agents, COD, nitrogen and phosphorus are further reduced. The effluent quality after the treatment of the SBR reactor is as follows: COD30~50mg / L, NH 3 -N3~5mg / L, TP0.4~0.5mg / L.

[0070] The effluent is then treated by the biological pond, and the natural purificatio...

Abstract

The invention relates to a high-efficiency treating technology and device for waste water. The high-efficiency treating technology includes the steps that firstly, after the waste water to be treated is collected through a waste water pipe network, the waste water is intercepted through grids, and particles and suspended matter with large particle sizes in the waste water to be treated are removed; secondly, the waste water enters a water collecting pool to be collected and stored, the water quality and the water amount of the waste water are balanced, and the water quality pH is adjusted; thirdly, the waste water enters a hydrolysis acidification pool to have hydrolytic acidification; fourthly, the waste water enters an EGSB anaerobic reactor, and the content of pollutants such as COD in the waste water is rapidly reduced; fifthly, the waste water enters an adjusting pool, and the amount of the waste water entering an SBR reactor is adjusted; sixthly, a pumping SBR reactor further removes pollutants such as COD, ammonia nitrogen, total nitrogen and total phosphorus in the waste water; seventhly, the waste water is naturally purified through a biological pond. The high-efficiency treating technology for the waste water has the advantages of being simple in technological process, capable of saving investment, good in treating effect, stable in operation, low in cost, easy and convenient to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection wastewater treatment, and relates to a high-efficiency treatment process and device for waste water, in particular to a high-efficiency treatment process and device for wastewater from livestock and poultry breeding, waste water from expressway service areas, and waste water from catering and tourism industries . Background technique [0002] With the development of the economy, the construction of expressways and related infrastructure in my country has developed rapidly. Since the first expressway, Shanghai-Jiajia Expressway, was completed and opened to traffic in 1988, by the end of 2009, the total mileage of expressways in China had reached 65,000 kilometers. Expressways have made important contributions to the development of our country's economy and society. Since the expressway generally passes through multiple cities and has a long journey, there will be service areas, to...
