Problems solved by technology

In the biological filter, according to the upward direction of the water flow, there are water inlet buffer, filter filter area, and water outlet buffer. The filter filter area includes the first filter area, the second filter area, the third filter area, and the fourth filter area. , and the height accounts for 20%, 50%, 20% and 10% of the filter area respectively; each filter area is filled with biomass fillers with different raw material ratios, and the biomass fillers are composed of henna plant biomass materials and inert fillers. This patent The sewage is purified by filling the filter area with different ratios of biomass fillers. Since there is no upward air force, channel flow, short flow, and dead zones will appear in the anaerobic filter, so that the polluted wastewater cannot be fully treated. , and the biomass material will eventually be decomposed and needs to be reinvested

Abstract

The invention discloses a multi-stage microfluidisation and deep filtration integrated type improved anaerobic filter. A water distribution area, a strong microfluidisation filler area, a weak microfluidisation filler area, a filtration filler area and a water outlet area are arranged inside the anaerobic filter from bottom to top in sequence; the volume of particulate fluidization fillers evenly arranged in the strong microfluidisation filler area accounts for 50-60% of the volume of the strong microfluidisation filler area, and the volume of particulate fluidization fillers evenly arranged in the weak microfluidisation filler area accounts for 30-50% of the volume of the weak microfluidisation filler area; a methane pipeline is arranged above the water outlet area and communicated with a methane collection system, a water inlet system and a circulating moisture system are arranged outside the anaerobic filter, and both the water inlet system and the circulating moisture system are communicated with the water distribution area. By means of the circulating moisture system, a turbulent relation is generated between the weak microfluidisation filler area, the strong microfluidisation filler area and aqueous phase, so that a microfluidisation effect is generated in the filler areas, mass transfer effect is improved, and the probability of generation of channel streams, short streams and dead zones in the filter is reduced.

Description

technical field [0001] The invention relates to a device for treating high-concentration organic refractory wastewater, in particular to an improved anaerobic filter with multi-stage microfluidization set depth filtration. Background technique [0002] Most of the wastewater in the chemical industry contains high-concentration refractory organic wastewater, and there are many unfavorable factors such as complex composition of wastewater, difficult degradation of wastewater, and greater impact of load shock on anaerobic reactors. Therefore, the treatment method of anaerobic biodegradation is mostly used at home and abroad. In an anaerobic system, microorganisms use the carbon source provided by high-concentration organic wastewater as an energy source for their own growth and metabolism. Through a series of complex chemical and biological processes, microorganisms convert refractory organic matter into simple inorganic small molecules and produce methane. and other energy ga...
