Abstract
The invention discloses a sewage treatment device. The sewage treatment device comprises a grille pool, an adjusting pool, a sand filter pool, a sand filter pool water preparation pool, manual rapid seepage pools and a reused water tank; a water outlet of the sand filter pool water preparation pool is connected with a plurality of manual rapid seepage pools, and the discharged water of each manual rapid seepage pool is discharged to the reused water tank; the reused water tank is connected with a backwash water inlet pipeline of the sand filter pool by virtue of a pipeline, the backwash water outlet pipe of the sand filter pool is connected to a backwash precipitation pool, the sludge of the backwash precipitation pool and the sludge of the adjusting pool are pumped to a sludge drying pool by virtue of a sludge pump, the sludge drying pool comprises a sludge drying pool body, a longitudinal separation plate is arranged in the sludge drying pool body so as to divide the sludge drying pool body into a left chamber and a right chamber, a sludge inlet is respectively formed in the upper parts of the left and right chambers, the lower parts of the left and right chambers are respectively transversely provided with a water permeable geotechnical cloth layer, a gravel layer and a perforated drainer from top to bottom, a water discharging opening is respectively formed in the lower ends of the left and right chambers of the sludge drying pool body, and a rainshed is arranged above the sludge drying pool. The treatment effect is good.
Description
technical field [0001] The invention relates to a sewage treatment system, in particular to a sewage treatment device. Background technique [0002] With the enhancement of people's awareness of environmental protection, sewage treatment has become a key issue of concern to governments of various countries. There are three main sources of sewage in my country, namely, decentralized domestic sewage in township residential areas, centralized domestic sewage in urban living areas, and industrial production processes. sewage. Using sand to purify sewage is a traditional sewage treatment method. The existing sewage treatment method has some shortcomings. The removal capacity of TN and TP is low, and some biochemical treatment ponds such as denitrification ponds need to be placed. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides another sewage treatment device, which is suitable for domestic sewage treatment in tow...
