Embodiment Construction

[0009] Figure 1 shows the annular domestic sewage high-efficiency purification biogas device, which consists of a sand trapping well [1], a first-level annular anaerobic tank [2], a sand-settling well [3], a second-level annular anaerobic tank [4], and aerobic The pool [5] is composed. They are connected in sequence through 30 cm diameter water pipes.

[0010] The sand trapping well [1] and the first-level annular anaerobic tank [2] are connected by a cement pipe with a diameter of 30 cm. The grit well [3] is connected to the secondary annular anaerobic tank [4], and the secondary annular anaerobic tank [4] is connected to the aerobic tank [5].

[0011] The structure of the primary annular anaerobic [2] and the secondary annular anaerobic pool [4] are basically the same. They are each composed of a circular ring and a retaining wall sandwiched by several concentric cylinders. The domestic sewage is composed of diameter A 30 cm cement pipe is introduced into the center of the pool....

Abstract

An annular high-efficient domestic sewage purifying methane apparatus consists of several annular fermentation pools and water retianing walls formed by several concentric circles. Compared with the new available common circular apparatus, the annular apparatus has three times over longer path for domestic sewage to pass through and thus greatly increased effective space for domestic sewage to stay. The present invention has reduced occupied area and domestic sewage purifying cost and raised domestic sewage purifying efficiency.

Description

Technical field: [0001] The present invention relates to an improved biogas device for purifying domestic sewage, which is suitable for efficient treatment of domestic sewage from various residences, living quarters, catering industry, etc., so that the treated domestic sewage can meet the discharge wastewater No. 1 in GB8978-1996 required by the National Environmental Protection Agency. Level standards. Background technique: [0002] According to the existing domestic sewage purification biogas digester standard atlas 90SS-1, the design scheme has been unable to meet the new maximum allowable discharge concentration standard of the second category of pollutants GB8978-1996. To meet the new discharge standards, it is necessary to increase the design volume and prolong the residence time of domestic sewage, which will greatly increase the cost. Summary of the invention: [0003] In order to solve the problems of large construction volume and high cost existing in the existing dom...
