Problems solved by technology

Unstabilized sludge, due to its high content of organic matter, is easily corrupted and produces stench, especially the sludge in the primary sedimentation tank, which contains a large number of germs, parasite eggs and viruses, which can easily cause the spread of infectious diseases

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] A sludge recycling system, referring to figure 1 , including a sludge thickener (1), a belt filter press (11), a fermentation room (2), and a finished product area (3) connected in sequence. The fermented clinker is sent into the clinker bin by the excavator, and stacked by the loader into stacks according to the order of leaving the bin. After about 7 days of aging, the finished product can be packaged and shipped out. Sewage collection canals are installed on the indoor ground of the turnover adjustment tank, fermentation tank and fermentation room, and the collected sewage enters the sewage treatment area (5), including buried JYZ integrated membrane treatment equipment (51) for treatment, and the sewage effluent is passed through Lift pump (52) to control valve 2 (53) biofilter or control valve 1 (54) sludge thickener. The composting treatment ro...

Abstract

The invention discloses a sludge recycling system, belongs to the technical field of sludge recycling, and aims at providing the sludge recycling system which is characterized by sludge reduction and has the advantage of effectively using sludge as fertilizer. According to the technical scheme, the sludge recycling system includes a sludge concentration basin, a belt filter press, a fermentation chamber and a finished-product area which are connected in sequence. Fermented cured materials are put into a cured-material bin by an excavator, according to an out-of-bin sequence, the fermented cured materials are stacked into stacks by a packing machine, and through curing for about seven days, finished-product packaging and outward transporting can be conducted. Sewage collection trenches are arranged on the ground in a turnover regulation basin, a fermentation basin and the fermentation chamber, collected sewage enters a buried-type JYZ integrated membrane treatment device and is treated, and sewage effluent passes through a lifting pump and reaches a biological filtering basin or the sludge concentration basin. The sludge recycling system has the advantages that through the optimization and fermentation of the sludge recycling system, the amount of the sludge is effectively reduced, and at the same time, the sludge fertilizer subjected to compost has the effects of good fertilizer efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of sludge resource utilization, in particular to a sludge resource utilization system. Background technique [0002] The national technical policy on urban sewage pollution control and the newly promulgated pollutant discharge standards for urban sewage treatment plants (GB 18918-2002) have clear requirements for sludge stabilization and farmland utilization in urban sewage plants. But the actual situation is that the construction of sewage treatment plants often only pays attention to the sewage treatment to meet the discharge standards. In recent years, due to the requirements of dephosphorization and nitrogen removal, many sewage biological treatment processes have evolved. For sludge treatment and disposal, the design generally only mentions the export and comprehensive utilization of dewatered sludge, without calculating its investment and frequent costs. cost, which will inevitably cause secondary pol...
