Abstract

The invention relates to a wastewater treatment system suitable for small and medium size farms and a solid waste comprehensive treatment method. The system comprises a sedimentation basin, a regulating reservoir, an efficient filtering basin, a plant purifying pond and a composting field which are connected in sequence. The efficient filtering basin comprises a plurality of efficient filtering basin modules, wherein each efficient filtering basin module comprises a filtering basin cavity and filtering materials arranged in the filtering basin cavity. A water distributing system is arranged on the upper portion of the efficient filtering basin, a main water outlet pipe is arranged on the lower portion of the efficient filtering basin, and a discharging port is formed in the side face of the efficient filtering basin. The efficient filtering basin is filled with the efficient adsorption materials which serve as carriers, and the adsorption materials are porous materials and have very large surface area so that pollutants in wastewater can be easily adsorbed, and the anaerobic fermentation efficiency can be improved; by means of the design of the device, absorption saturated materials can be easily discharged and used, the materials obtained after absorption saturation can be used for producing organic fertilizer together with excrement of the farms, the fertilizer efficiency is improved, and waste is recycled.

Description

technical field

[0001] The invention relates to a waste water treatment system suitable for small and medium farms, and belongs to the technical field of waste water treatment. Background technique

[0002] In recent years, my country's large-scale and intensive livestock and poultry breeding industry has flourished, and the large-scale pig breeding has shown a trend of accelerated development, and the number of large-scale pig farms is also increasing. In 2010, my country's large-scale pig farms sold 332.623 million heads. While satisfying the supply of livestock products for people, it also caused serious pollution to the surrounding environment. Since many small and medium-sized pig farms have no sewage treatment measures, pig farms The surrounding sewage flowed horizontally, and the smell was even more unbearable, which seriously affected the normal life of the surrounding villagers. At present, most of the large-scale pig farms in my country adopt the water flushing pro...
