Technical Field

The invention belongs to the technical field of septic tanks, and particularly relates to a novel worm bed septic tank.

Background

The septic tank is equipment for treating excrement and filtering and precipitating; the principle is that the condensate decomposes at the bottom of the tank, the hydrate on the upper layer flows away when entering the pipeline, the pipeline is prevented from being blocked, and sufficient time is provided for the hydrolysis of the condensate (garbage such as excrement and the like); the septic tank refers to a small-sized treatment structure for carrying out cellular precipitation on domestic sewage and carrying out anaerobic digestion on sludge.

The application of the traditional septic tank has been over one hundred years, the technical route is a mode of contacting sewage and sludge, the deposited sludge is digested and degraded to generate digestion gas such as methane, carbon dioxide, hydrogen sulfide and the like, the sludge is disturbed by the floating action of the digestion gas, and the sludge and biological flora can be mixed more fully by the disturbance action of the digestion gas on the sludge, so that the digestion and degradation are facilitated.

The current septic tank bottom mud rises along with digestion gas, and the bubble overflows the back, and mud downwards deposits again, and sewage is polluted again to these mud that rise and deposit, is carrying out the clear transfer of drawing of a large amount of excrement and urine mud, has caused secondary pollution, and septic tank mud will become water pollution's pollution source, and the jam problem of septic tank has seriously influenced user's normal life, is the septic tank application problem that awaits the opportune moment and solve.

Disclosure of Invention

The invention aims to solve the problems that sludge at the bottom of the existing septic tank rises along with digestion gas, bubbles escape, the sludge is precipitated downwards again, the ascending and precipitated sludge pollutes sewage again, a large amount of excrement sludge is removed and transferred to cause secondary pollution, and the sludge in the septic tank can become a pollution source of water pollution.

The invention relates to a worm bed septic tank, which comprises a shell, a three-dimensional reticular packing layer, a worm bed, a separating steel frame platform, a filter screen, a splash pan, a water outlet pipe, an exhaust pipe and a water inlet pipe, wherein an inner cavity is enclosed by the shell and a top cover;

the water outlet pipe is vertically arranged, one end of the water outlet pipe penetrates through the top cover, and the other end of the water outlet pipe penetrates through the worm bed and extends into the bottom three-dimensional reticular filler layer; one end of the exhaust pipe penetrates through the top cover, and the other end of the exhaust pipe penetrates through the worm bed and extends into the three-dimensional reticular packing layer at the bottom.

The invention provides a novel worm bed septic tank, wherein excrement sewage is separated from liquid through a rice-shaped splash pan, (stainless steel) filter screen, a worm bed and a three-dimensional reticular packing layer, solid sewage is decomposed through worms, the liquid sewage is discharged to the next unit for independent treatment, the water treatment efficiency is effectively enhanced, the burden of a downstream water treatment device is reduced, and solid substances can be converted into fertilizers through worms and used as supplement of ecological fertilizers in rural areas.
