Abstract

The invention discloses a domestic wastewater treatment method based on GY-2 type water treatment filler. The method comprises the steps as follows: a reactor is filled with the GY-2 type water treatment filler to form a filter bed; domestic wastewater is distributed from the upper side of the filter bed, so that the wastewater passes through the filter bed. The GY-2 type water treatment filler comprises a main material and an auxiliary material; the main material is obtained from a fermented product of waste organic matter and a carbon-containing raw material in an anaerobic environment through composting; the auxiliary material is prepared from agricultural and forestry residues through fermentation; the mass ratio of the main material to the auxiliary material is (30-40):100. The methodcan effectively treat organic wastewater to realize targeted treatment of different wastewater and has the advantages that blockage cannot be caused easily, the service life is long, the cost is lowand the like. The invention also provides a treatment device of the organic wastewater. The device comprises a reactor, a water distribution pipe, a mechanical ventilating pipe and a filter bed and ishigh in treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of domestic wastewater treatment, in particular to a treatment method and device for rural domestic wastewater based on GY-2 water treatment fillers. Background technique [0002] Rural domestic sewage has the characteristics of wide area, dispersion, multiple sources, rapid growth, difficult collection, and low treatment rate. At present, the main treatment technologies can be classified into two categories, namely natural treatment systems and biological treatment systems. The natural treatment system mainly uses the self-purification ability of nature to treat domestic sewage, such as artificial wetland technology, soil infiltration purification, oxidation pond, etc. The biological treatment system mainly uses anaerobic or aerobic microorganisms to digest and decompose organic matter and other pollutants in water, mainly including AO process, SBR process, MBR process, biological trickling process, activa...
