Slurry feces biochemical treatment system

Abstract

The invention discloses a pulp excrement biochemical treatment system. The excrement biochemical treatment system comprises an excrement discharge pond, a coarse screen machine, a thin screen machine, a sand setting device, a fine screen machine, a medicating device, a beating machine and an excretion pond, wherein the excrement biochemical treatment system comprises a excrement discharge storage step, a coarse matter sorting step, a thin material sorting step, a sand setting biochemical treating step, a fine material sorting step and a pulp refining step; the coarse screen machine and the thin screen machine are configured to respectively sort waste matter according to the particle size, and the treating effect is good; the sand setting biochemical integrating mechanism has obvious sand-setting effect; the beating machine is configured to further perform micronization treatment on the excrement overflow matter to achieve the pulp matter effect so as to subsequently purify the harmful matter in the excrement; the aerobic reaction in the excrement purification treatment is facilitated by removing the ammonia element, the normal propagation of the aerobic bacteria is protected, and the subsequent aerobic reaction effect is improved.

Description

technical field [0001] The invention relates to the technical field of urban excrement treatment, in particular to a biochemical treatment system for slurried excrement. Background technique [0002] At present, the feces in the concentrated areas such as towns and cities adopt the mode of cesspit storage and unified transportation, that is, the feces produced by the residents are temporarily stored in the prefabricated cesspit, and then transported to the designated place by external suction (unloading) manure trucks. For example, in areas with small populations such as rural areas, most of the feces produced are directly discharged or treated as fertilizer for crops. [0003] In view of urban areas, how to carry out effective and harmless treatment is a problem that everyone is more concerned about now. With the acceleration of urbanization and the strengthening of environmental sanitation protection, the treatment of feces has become a top priority. In the current techno...

Problems solved by technology

In the current technology, such as the Chinese utility model patent "a kind of urban public toilet excrement, septic tank sludge scum centralized treatment station device" (notification number is CN201245532Y) whose patent number is CN200820116351.9; Liquid separator, centrifugal dehydrator, receiving tank, lifting pump, rotary solid-liquid separator, screw pump, horizontal centrifugal dewatering machine, and manure tank are arranged in a row in sequence, and the front of the receiving tank is equipped with a grid decontamination There is also a dosing pipe connected to the pipeline behind the screw pump, and a pipeline connected to the urban sewage pipe network is installed behind the rotary solid-liquid separator and the horizontal centrifugal dehydrator; this technology cannot effectively remove the feces. Ammonia element, its smell spreads to the surrounding area, which is not conducive to the protection of the surrounding environment; equipped with a solid-liquid separator and a grid decontamination machine, without finely treating the feces, it is easy to cause pipeline blockage; so there are still big problems in this technology , which is not conducive to subsequent oxidation treatment, that is, it cannot meet the purpose of harmless final treatment of feces
