Characteristics of Farming sewage
-
-
-
Farming sewage mainly includes urine, feed residues, residual manure and washing water, and in some places it also includes domestic wastewater generated during the production process. It is a high-concentration organic sewage with a large content of suspended solids and ammonia nitrogen. After this untreated sewage enters the natural water body, the content of suspended solids, organic matter and microorganisms in the water increases, changes the physical, chemical and biological composition of the water body, and deteriorates the water quality.
-
The sewage also contains a large number of pathogenic microorganisms that will spread through the water body and endanger the health of humans and animals. Farming sewage has the typical "three highs" characteristics, that is, high organic matter concentration, COD as high as 3000-12000mg/l, ammonia nitrogen as high as 800-2200mg/l, suspended SS is dozens of times higher than the standard, the color is deep, and it contains a lot of bacteria and organic phosphorus. The main characteristics of farm sewage are large drainage, concentration, and strong hydraulic shock load; high concentration of organic matter, fast hydrolysis and acidification, good biodegradability, and good sedimentation performance. The sewage is often accompanied by disinfectant water, heavy metals, residual veterinary drugs, and various Pollutants such as zoonotic pathogens.
Farming wastewater treatment solutions
Choose the appropriate treatment process and related equipment according to the waste water volume and water quality. Ensure that the sewage can be effectively treated to reach the discharge standard, and it can save energy consumption and economic investment.
Part of the required equipment
-
-
Buried integrated sewage treatment equipment
-
The deodorization method of the buried domestic sewage treatment equipment adopts conventional high-altitude exhaust, and is also equipped with soil deodorization measures. The product has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.
-
Product features: ● Buried below the ground surface, the ground surface above the equipment can be used as greening or other land, without the need for building, heating, and insulation. ● The entire equipment processing system is equipped with a fully automatic electrical control system and equipment failure alarm system, which is safe and reliable in operation
-
-
Dissolved air flotation machine
-
The air flotation method is the dissolved air water produced by the dissolved air system. It is mainly used for the separation and removal of fine suspended matter with a density close to water.
-
Product features：● Small footprint, low energy consumption, convenient installation and transportation. ● High degree of automation, convenient operation and simple management. ● High dissolving gas efficiency and stable treatment effect.
-
-
Inclined tube precipitator
-
The inclined plate (tube) sedimentation tank is an efficient combined sedimentation tank designed according to the theory of shallow pool sedimentation; a lot of dense inclined pipes or inclined plates are set in the settlement area to make the suspended impurities in the water settle in the inclined plate or inclined tube.
-
Product features: ● Simple structure, no wearing parts, durable and less maintenance. ● Stable operation and easy operation. ● Less power and energy saving. ● It occupies a small area, low investment, quick launch and high efficiency. ● The residence time is short, the precipitation effect is high, the treatment efficiency is high, the aeration intensity is low, and there is no need for sludge backflow.
