Embodiment 1

[0035] A treatment process for agricultural sewage, comprising the following steps:

[0036] 1. Initial inspection: Sampling to detect the amount of pollutants in the sewage;

[0037] 2. Filtration: Separation of solid insoluble matter in sewage;

[0038] 3. Disinfection, sterilization, sedimentation: add a disinfectant to the filtered water, stir for half an hour, and let it settle for 30 minutes; the disinfectant is nano-silver and unslaked lime in equal parts by weight; the disinfectant The dosage of fungicide is 1g / m 3 sewage;

[0039] 4. Electrolysis: Add a catalyst to the sewage after disinfection and sterilization treatment into the electrolytic cell, feed direct current, and ionize and decompose the pollutants; the catalyst is a composite catalyst, consisting of the following raw materials in parts by weight: 10 parts of iron oxide, 10 parts of ferrous iron, 10 parts of polyacrylamide and 10 parts of graphene oxide;

[0040] 5. Heavy metal treatment: add a heavy meta...

Abstract

The invention discloses an agricultural wastewater treatment technology. The agricultural wastewater treatment technology comprises the following several steps: 1, primarily detecting; 2, filtering; 3, disinfecting, sterilizing and settling; 4, planting a turf; 5, electrolyzing; 6, treating heavy metals; 7, performing quality inspection. Agricultural sewage is treated step by step on a large scalein allusion to the characteristics of the agricultural sewage, pollutants in the sewage are finely classified and pertinently removed, and the agricultural sewage is recycled after the quality inspection is passed, so that resources are saved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an agricultural sewage treatment process. Background technique [0002] Agricultural sewage refers to the sewage or liquid substances discharged during the process of crop cultivation, livestock raising, and agricultural product processing, which affect human health and environmental quality. Its sources mainly include farmland runoff, feedlot sewage, and agricultural product processing sewage. Sewage contains various pathogens, suspended solids, fertilizers, pesticides, insoluble solids and salt, etc. The amount of agricultural sewage is large and the impact is wide. Nutrient elements such as nitrogen and phosphorus in sewage enter rivers, lakes, inland seas and other waters, which can cause eutrophication; pesticides, pathogens and other toxic substances can pollute drinking water sources and endanger human health; cause large-scale soil pollution and destroy ecosystems balan...
