Multifunctional anaerobic biogas fermentation tank structure and its application method

Abstract

The invention relates to a multifunctional anaerobic biogas fermenting tank structure which comprises a biogas fermenting tank, a feed port, discharge port and a sludge discharge port, wherein the feed port is connected with a water distributor on the bottom of the biogas fermenting tank through a feed pipe; the sludge discharge port communicates with the bottom of the biogas fermenting tank through a sludge discharge pipe; the upper part of the biogas fermenting tank is connected with a closed shell in a jointless mode; the discharge port is connected with the shell through a discharge pipe; a gas storage hood is arranged inside the shell; and the connecting end between the gas storage hood and shell is provided with a sliding mechanism which is used for matching with the gas storage hood to make a vertical reciprocating sliding motion in the shell. The multifunctional anaerobic biogas fermenting tank structure is simple in structure, is convenient for implementing functions, and integrates the functions of anaerobic biogas fermentation, biogas collection and storage, automatic sludge discharge, and biogas slurry storage and discharge. Compared with the traditional biogas fermenting tank, the multifunctional anaerobic biogas fermenting tank provided by the invention has the advantages of multiple functions, low investment and small occupied area, is convenient to use, has wide application prospects in the fields of rural domestic waste treatment and planting / cultivation combined aquaculture wastewater cyclic utilization, and has important meanings for improving the rural ecological environment.

Description

technical field [0001] The invention provides a structure of a multifunctional anaerobic biogas fermentation tank and a use method thereof, which are applied in the field of recycling of domestic sewage and breeding wastewater in rural areas. Background technique [0002] With the rapid development of the livestock and poultry breeding industry and the rural economy, the price of rural labor has also risen accordingly. The traditional land use methods of farming wastewater and domestic wastewater in rural areas are mainly completed by labor, which is difficult to maintain due to the influence of economic interests. At present, there are no convenient equipment and facilities for the recycling of breeding wastewater and domestic wastewater, resulting in high costs for rural retail farming wastewater and domestic wastewater recycling, which directly affects the economic benefits of traditional land use of rural wastewater. However, if these rural household wastewater and domes...

Problems solved by technology

[0002] With the rapid development of the livestock and poultry breeding industry and the rural economy, the price of rural labor force has also risen accordingly. The traditional land use methods of rural household waste water and domestic waste water are mainly completed by labor, which is difficult to maintain due to the influence of economic interests.

At present, there are no convenient equipment and facilities for the recycling of breeding wastewater and domestic wastewater, resulting in high costs for rural retail farming wastewater and domestic wastewater recycling, which directly affects the economic benefits of traditional land use of rural wastewater

However, if these rural household wastewater and domestic wastewater are discharged directly without treatment or land use, it will definitely destroy the rural ecological environment and affect the rural sanitation environment.
