Problems solved by technology

[0005] However, the above-mentioned technical solutions mainly use the method of introducing drying or microbial preparations to treat such sewage. Firstly, the cost is high, and then the treatment reaction time is long, and the process is also relatively complicated. For suspended sewage that affects the discharge quality Insufficient quality processing

Embodiment 1

[0027] A method for treating sewage in a farm, comprising the steps of:

[0028] Step 1, separate the sewage from the farm from wet to dry, discharge the solid dregs, and send the liquid sewage into the mixing device to mix with the catalytic water device at a ratio of 1:1 and deodorize;

[0029] Step 2, adding a flocculant to the liquid sewage mixed and deodorized in step 1 and catalytic water for mixing, and then performing sedimentation treatment, discharging the settled sediment, and sending the liquid part to the next step;

[0030] Step 3, adding alum diluent to the liquid part treated in step 2 and performing stirring, mixing and sedimentation treatment, discharging the treated sediment, and sending the liquid part to the next step;

[0031] Step 4, adding alum diluent to the liquid part after step 3 treatment, and adding catalytic water at the same time, after mixing, sedimentation is carried out again, after sedimentation, the sediment is discharged, and the remaining...

Abstract

The invention discloses a farm wastewater treatment method, and relates to the technical field of wastewater treatment. The method includes the steps of dry-wet separation, flocculation sedimentation,decolorization, ammonia and nitrogen removal and the like. By mixing catalytic water and performing flocculation, ammonia and nitrogen removal, decolorization and the other processes, the farm wastewater treatment method greatly increases the speed of farming wastewater treatment, reduces the treatment cost of such wastewater, is convenient to implement, and helps solve the problem of wastewatertreatment and discharge in small farms.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment method for farms. Background technique [0002] Under the background of generally encouraging the expansion of breeding production in rural areas, my country's livestock and poultry breeding industry has developed vigorously, showing a trend of industrialization, scale and regionalization in recent years. Due to the large amount of wastewater discharged from large-scale livestock and poultry farms, the high concentration of pollutants and the long-term lack of attention and management in my country, it has become one of the main sources of pollution in most regions and watersheds in my country, causing serious environmental pollution and a large amount of nitrogen and phosphorus every year. Resource loss and waste. Therefore, how to deal with farm sewage has become a major problem that plagues the development of enterprises. [0003] In the prior art,...
