Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0024] Such as figure 1 , figure 2 and image 3 As shown, the land treatment system is a tank with a trapezoidal cross-section, which can be excavated below the ground, with an anti-seepage film 8 laid around and at the bottom. From bottom to top, there are sand layer 9, water distribution layer 10, biological filler and The water collection layer 11, the soil layer 12, and the water collection vertical pipe 15, the water collection horizontal pipe 5, the water collection branch pipe 6 and the water collection main pipe 13 laid in the biological filler and the water collection layer 11. The anti-seepage membrane 8 is located on the bottom and the hypotenuse of the designed section, and its main function is to prevent sewage from seeping down and polluting groundwater.

[0025] The pretreated sewage passes through the water inlet pip...

Abstract

The invention discloses a water inlet outlet pipe network system of efficient sewage land treatment process, comprising a water inlet pipe network and a water outlet pipe network; wherein the water inlet pipe network is arranged at one side of land treatment system and is composed of a water inlet pipe, a water inlet branch pipe and a water distributing pipe which are sequentially connected, the water outlet pipe network is arranged at the other side of the land treatment system and is composed of a water collector branch pipe, a water header and a drain pipe which are sequentially connected,the water distributing pipe comprises a plurality of water distributing vertical pipes which are vertically arranged and penetrates a biological filler and water collection layer and a water distribution layer, and the water outlet pipe is paved into the biological filler and water collection layer. The invention improves water distribution and water discharging modes, vertical water inflow is adopted, top transverse water discharging is adopted, thus improving volume utilization factor of system; less pipes are adopted, uniform water distribution and water discharging are realized, and investment is less; and construction is rapid and simple, and pipe damage ratio is low.

Description

technical field [0001] The invention relates to a water inlet and outlet pipe network system of a sewage high-efficiency land treatment process, belonging to the technical field of sewage biological treatment. Background technique [0002] The sewage land treatment system purifies sewage by using an ecological sewage treatment system composed of soil-microbe-plants for sewage treatment, and decomposes and transforms pollutants through the action of anaerobic, facultative and aerobic microorganisms. The way of water intake is mainly divided into two types: upward flow and downward flow. At present, the research focus is mainly on the selection of fillers, but there are few studies on the layout of the inlet and outlet pipe networks. [0003] Chinese patent application number 200820022241.6: Upward flow enhanced sewage land treatment system, using soil-microbe-biological filler-plant ecological sewage treatment system, excavated below the ground, with impermeable membranes ar...
