Embodiment Construction
[0005] In the present invention, the waste water containing feces is stirred and crushed to eliminate block columnar substances, so that the feces are fully dissolved in water, and the sewage water containing feces of less than 20 meshes is pumped into humification equipment for humification, and biogas and bio-yellow are produced during humification. Humic acid, biological humic acid solid-liquid mixture, after the mixture is catalyzed, solid-liquid separation is carried out, the separated aqueous solid is dried to obtain biological humic acid products, and the separated liquid is purified to obtain liquid biological fulvic acid, liquid biological fulvic acid After drying, a solid biological fulvic acid product is obtained. There is no discharge of waste water, waste gas or solid waste during the production process.

The invention aims to provide a method for simultaneously producing biological fulvic acid, biological humic acid and a biogas through using all manure-containing sewages in a non-pollution manner. An apparatus for realizing the method comprises a stirring crusher, a humic materialization device, a biogas purifier, a gas storage tank, a solid-liquid separator, a purifying device, a drying device and a catalyst. Compared with the extraction of the biological fulvic acid and the biological humic acid through using coal, the method provided in the invention has the advantages of renewable resource, no pollution, no waste discharge, and production of the renewable energy biogas, and belongs to the low carbon economy and circular economy fields.
Description
technical field [0001] The invention aims at producing biological fulvic acid, biological humic acid and biogas from all sewage containing feces. It belongs to the technical fields of biotechnology, new energy, new materials, energy conservation and environmental protection. Background technique [0002] Sewage containing feces has become a major source of pollution. The traditional treatment method consumes a lot of energy, has no benefit, and causes secondary pollution. Traditional fulvic acid, humic acid is mainly extracted from non-renewable low-heat plant coal, and the content of fulvic acid in low calorific value coal is particularly small. The pollution-free production of fulvic acid, humic acid and biogas from sewage containing feces has realized zero discharge and resource utilization of sewage containing feces. The problem of manure-containing sewage treatment and renewable resource production of fulvic acid, humic acid and renewable energy is solved. Contents ...
