Convenient-to-clean sewage treatment device for agricultural irrigation

Abstract

The invention discloses a convenient-to-clean sewage treatment device for agricultural irrigation. The convenient-to-clean sewage treatment device mainly comprises a treatment table, a filtering assembly, a sewage treatment assembly and an irrigation assembly are sequentially arranged on the treatment table; the filter assembly mainly comprises a filter shell, an annular filter screen and a cleaning clamping brush; the sewage treatment assembly mainly comprises a treatment box body, a treatment agent bin and a stirring mixer; a water inlet is formed in the upper top surface of the treatment box body, the water inlet is connected with a liquid outlet formed in the lower part of the filtering shell through a water pump and a pipeline, and a partition plate is arranged at the lower part in the treatment box body and is used for vertically dividing the treatment box body into a stirring area and a standing area; the irrigation assembly comprises an irrigation nozzle, and the irrigation nozzle is connected with a water outlet formed in the outer wall of the treatment box body in the standing area through a pipeline and a water pump. The device disclosed by the invention can realize self-cleaning, so that the sewage treatment efficiency is improved, and the device is green, energy-saving and environment-friendly through irrigation after sewage treatment.

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...

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
