A device and method for strengthening the integration of quality separation and resource utilization of rural sewage

Abstract

The invention discloses a device and a method for strengthening the integration of quality separation and resource utilization of rural sewage. The device includes a black water resource treatment system and a grey water resource treatment system that are separated and integrally arranged; the black water resource treatment system includes: The black water inlet unit, the black water sedimentation tank, the anaerobic trickling drum filter and the black water outlet unit are arranged in sequence; the grey water resource treatment system includes the grey water inlet unit, the grey water sedimentation tank, Upflow pinhole aeration contact tank and grey water outlet unit; a reflux system is set between the grey water outlet unit and the anaerobic trickling filter drum filter. The present invention treats black water and grey water respectively, and black water and grey water are respectively subjected to anaerobic and aerobic treatment, different treatment methods are selected according to different water quality, and after different treatments, they can be reused in different ways according to water quality, Compared with the traditional mixed treatment, the treatment difficulty and cost are reduced, the treatment efficiency and the effluent quality are improved, and the effluent can be effectively utilized as a resource.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more particularly to a device and method for strengthening the integration of quality separation and resource utilization of rural sewage. Background technique [0002] my country is a big agricultural country, and the rural population and rural area have a huge base, and the situation of rural sewage treatment is quite severe. Most rural areas do not have special sewage collection pipe networks and sewage treatment systems, which means that the vast majority of rural sewage is directly discharged without treatment, posing a great threat to the ecological environment and safety. A small number of rural areas with processing capacity still have great defects in their processing methods. [0003] Rural sewage can be divided into black water and grey water. Black water is collected from toilets, and its main components are feces and urine. The concentration of pollutants such as nitro...

Problems solved by technology

However, the existing rural sewage treatment methods often ignore the differences in the nature and content of the two types of sewage pollutants and the difficulty of treatment, and concentrate the two types of sewage for mixed treatment, which not only increases the difficulty of treatment and increases the cost of treatment, but also affects The resource-based substances contained in the two types of sewage cause invisible waste
