Biosorption system

Abstract

The invention discloses a biosorption system. The biosorption system comprises an ecological pool, wherein a group of water distribution pipes are arranged at the bottom of the ecological pool and are communicated with a gas and water mixing pump; aquatic plants, snails and mussels are arranged in the ecological pool. Non-industrial sewage is drained into a biosorption purification pond for biosorption and filtration after treatment in the preceding stage, COD (chemical oxygen demand), BOD (biological oxygen demand), colloid, oil, ammonia-nitrogen, phosphorus, calcium and magnesium ions and the like in water are degraded and absorbed, and accordingly, water is purified and softened, the requirement of reclaimed water is met, and the water is further reused; the biosorption system is low in energy consumption and environment-friendly, an entire biotic community is cultivated and used for purifying water, absorbing and decomposing harmful pollutants in water, and thus, waste is turned into treasure; excess aquatic weeds, snails and mussels are all high-quality fresh organic feed for livestock and poultry. The biosorption system is applicable to purification of agricultural culture wastewater and other non-industrial wastewater as well as cycle and sustainable development of the ecological agriculture.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a biological adsorption system. Background technique [0002] 1 Pollution Status of Livestock and Poultry Breeding Wastewater [0003] The livestock and poultry industry is an important part of my country's agriculture and rural economy. The environmental pollution caused by the vigorous development of the livestock and poultry industry is becoming more and more serious. The emissions of major pollutants from domestic, domestic and industrial sources were analyzed and summarized. Among the agricultural sources, the COD and ammonia nitrogen emissions from the livestock and poultry industry were 12.6826 million tons and 717,300 tons respectively, accounting for 95.8% and 78.1% of the agricultural source COD and ammonia nitrogen emissions, accounting for 41.9% of the national COD and ammonia nitrogen emissions and 41.5%.

[0004] 2 Hazards of livestock and poultry breeding wastewater

[0006] 2.1 Harm to water body

[0008] 2.2 Harm to the atmospheric environment

[0010] 2.3 Harm to farmland and crops

[0011] Wastewater from livestock and poultry breeding industry contains more nitrogen, phosphorus, potassium and other nutrients. If it is directly, continuously and excessively applied without any treatment, it will have adverse effects on the growth of soil and crops, such as reducing crop yields. , delay the maturity period, affect the production of subsequent crops, etc.
