Technology and system suitable for country and dispersive type sanitary sewage purification

Abstract

The invention provides a technology and system suitable for country and dispersive type sanitary sewage purification. The technical scheme of the technology and the system is as follows: for the technology and the system suitable for country and dispersive type sanitary sewage purification, the system comprises a water distributing well; sanitary sewage is collected to the water distributing well; the sanitary sewage in the water distributing well is pumped to an anaerobic biological filter through an elevator pump for being carried out first-step purification as well as sedimentation; a sludge elevator pump is arranged inside the anaerobic biological filter and is used for elevating biochemical sludge to a septic tank; water subjected to the first-step purification is pumped to a buried biological filter for being carried out second-step purification; and water subjected to the second purification can be reused. The technology and the system have the advantages of simple maintenance, convenience for management and little influence on over-ground cultivation although large areas are occupied.

Description

technical field

[0001] The invention relates to a process and system for purifying sewage, in particular to a process and system suitable for purifying rural and dispersed domestic sewage. Background technique

[0002] Domestic sewage in rural areas affects the safety of groundwater and the health and sanitation of farmers. Therefore, the improvement of rural water environment has become a hot topic in the construction of new countryside, and it is also one of the key technologies for building a new socialist countryside. The discharge characteristics of rural domestic sewage are as follows: 1) the discharge is scattered and wide-ranging; 2) the discharge is intermittent and fluctuates greatly; 3) the water quality is relatively stable, and the content of organic matter and nutrients such as nitrogen and phosphorus is relatively high.

[0003] The following factors should be considered in the selection of rural sewage purification process. One is to meet the current standar...

Embodiment Construction

[0018] In order to clearly illustrate the technical characteristics of this program, a specific implementation will be adopted below, combined with its

[0019] Accompanying drawing, this scheme is described.

[0020] As shown in the drawings, the present invention is a process and system suitable for rural and decentralized domestic sewage purification, including a water distribution well 14, collecting domestic sewage to the distribution well 14, and the sewage in the distribution well 14 is sent to the anaerobic The first step of purification and sedimentation is performed in the biological filter, and a sludge lifting pump 16 is installed in the anaerobic biological filter to lift the biochemical sludge to the septic tank, and the water purified by the first step of the anaerobic biological filter Collected into the water collection tank 18, and passed into the buried biofilter for the second step of purification, the water after the second step of purification is collecte...
