Problems solved by technology

[0003] However, traditional sewage treatment and agricultural irrigation devices often have low working efficiency, and it is difficult to meet long-term irrigation operations. According to our investigation, we found that the main problem lies in the filtration link and sewage treatment link. The filter screen of the traditional device is partly due to For long-term continuous use, if effective and timely cleaning is not carried out, then there will be slow filtration, which will cause the problem of sluggish irrigation water, and in the sewage treatment process, the traditional treatment device has low stirring efficiency and cannot be used very well. The sewage and flocculant and other treatment agents are mixed with the sewage quickly and fully, and the supernatant liquid cannot be discharged efficiently. Due to these problems, the sewage injection and irrigation water are relatively sluggish, resulting in low irrigation efficiency. Therefore, a new type of combined agricultural irrigation and sewage treatment device is needed to solve these problems

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for agricultural irrigation which is easy to clean. Background technique [0002] Sewage irrigation refers to irrigation that uses treated sewage that meets the irrigation water quality standards as the water source. Urban sewage is not only an important water source for paddy fields in the suburbs, but also an important source of fertilizer. According to the measurement, the sewage contains many nutrients such as nitrogen, phosphorus, potassium, zinc, magnesium, etc., and is rich in suspended organic matter. Therefore, the paddy field irrigated by sewage saves fertilizers, reduces costs, and the soil fertility continues to increase. Sewage mainly comes from domestic sewage and industrial sewage. Domestic sewage has good water quality and high fertilizer content, which is beneficial to rice. Industrial sewage contains some heavy metal salts t...
