Embodiment 1

[0029] Example 1, such as Figure 1-7 Shown: the domestic sewage artificial fast seepage purification system of the present invention is composed of grid tank 1, regulating tank 2, sand filter tank 3, sand filter tank distribution tank 4, artificial quick seepage tank 5, reuse water tank 6, backwash sedimentation tank 7. It is composed of sludge drying tank 8, canopy 9, controller 10, valve 11, water pump 12, liquid level gauge 13 and other components.

[0030] The domestic sewage in the town enters the grid pool 1 through the pipe network, and the outlet of the grid pool 1 is connected with the water inlet of the regulating pool 2, and the outlet water of the regulating pool 2 is pumped to the water inlet of the sand filter tank 3 through the pump 12, and the water pump A valve 11 is set on the water outlet pipe of 12, and the liquid in the sand filter 3 is discharged from the lower liquid outlet to the sand filter water distribution pool 4, and the water outlet of the sand f...

Abstract

The invention discloses a constructed domestic-sewage rapid infiltration and purification system. The water outlet of a lattice tank is connected with the water inlet of an adjusting tank; water in the adjusting tank is pumped into the water inlet of a sand filter by a water pump; a liquid in the sand filter is discharged into a sand filter water distribution reservoir from a liquid outlet at the lower part; the water outlet of the sand filter water distribution reservoir is connected with a plurality of constructed rapid infiltration tanks; water flowing out of the constructed rapid infiltration tanks is discharged into a recycling water tank; a liquid indicator is arranged in the adjusting tank; a valve is arranged on a water outlet pipe of the water pump; a water pump control terminal of a controller is connected with the water pump, and a valve control terminal of the controller is connected with the valve; the water pump is controlled to work by the liquid indicator; the recycling water tank is connected with a backwashing water inlet pipeline of the sand filter tank via a pipeline; a backwashing water outlet pipeline of the sand filter tank is connected with a backwashing sedimentation tank; sludge in the backwashing sedimentation tank and sludge in the adjusting tank both enter a sludge drying tank. The constructed domestic-sewage rapid infiltration and purification system is convenient to use and low in construction cost.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to an artificial rapid osmosis purification system for domestic sewage. 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-mentioned technical problems, the present invention provides another artificial rapid osmosis pu...
