Abstract

The invention discloses a device and method for strengthening treatment of anaerobic sewage by using solar energy, belonging to the field of purification of anaerobic sewage. The device for strengthening treatment of anaerobic sewage by using solar energy comprises an anaerobic reactor, wherein a metal electrode plate is arranged in the anaerobic reactor, and is connected with a solar direct-current generating system. In the invention, the anaerobic reactor is externally connected with the solar direct-current generating system, novel active catalysis micro-electrolysis filling is added into the reactor through the electrode plate in a sludge area of the reactor after particle sludge is acclimatized, hardly-degradable matters are removed under the coaction of an electrode electric field, the filling and particle sludge microorganisms, and running of the reactor is particularly strengthened under the condition of low temperature, so that energy consumption can be lowered, the removal rate of the hardly-degradable matters can be effectively increased, and continuous and stable running of the reactor is kept. The device and the method are mainly suitable for biological strengthened treatment of high-concentration slightly-degradable waste water such as industrial waste water, garbage percolates and the like.

Description

technical field [0001] The present invention relates to a bioaugmentation device and method in the field of anaerobic sewage purification, more specifically, it relates to an anaerobic sewage treatment strengthening device and method using solar energy, which is mainly suitable for industrial waste water, landfill leachate and other high Biointensive treatment of refractory wastewater with high concentrations. Background technique [0002] The concentration of pollutants in high-concentration refractory industrial wastewater is high, the biodegradability of wastewater is poor, and it is harmful to the ecological environment and human health. The treatment effect is poor with traditional treatment processes, and there are great difficulties in technology and economy. It is a long-term problem in the field of industrial wastewater treatment. existing technical problems. In the prior art, there are physical and chemical treatment processes, such as: activated carbon adsorption...
