Abstract
The invention discloses an automatic production process for direct sludge drying through filtration and an automatic production line. The defoamed and deodorized sludge is pumped into an automatic sludge press filtration device through a slurry pump for treatment so as to reach the aim of sufficient drying through filtration. Through the smart arrangement, the automatic production line makes use of a water guide rod, a filter board and the like inside the production line so as to carry out the multilevel press filtration of the sludge. The automatic production process for direct sludge drying through filtration can be used to directly dry the sludge (or slurry) through filtration and completely reutilize the sludge, thereby realizing the cancellation of a sludge landfill. The automatic production line for direct sludge drying through filtration has the advantages of great effective press filtration volume, simple structure, low manufacturing cost and strong resistance to corrosion and compression.
Description
Technical field
The present invention relates to a kind of sludge treatment technique, particularly a kind of directly filtering sewage sludge automatic production process and automatic production line.
Technical background
The processing of wet mud is the human difficult problem for a long time of puzzlement.According to statistics, the wet sludge quantity of the existing every family of China Sewage Plant discharging every day is 50m
3～120m
3, and the sludge landfill in a city, the wet sludge quantity that admit every day mostly is 200m
3～300m
3Because the Sewage Plant that city need be equipped with often reaches 4-8 house and does not wait, therefore rely on landfill not deal with problems, usually cause mud directly to be thrown aside, and the mud of throwing aside takies the big area land resources, cause the sludge resource waste, more can produce serious secondary pollution, as: landfill yard large amount of sewage osmosis pollution underground water source; Sludge fermentation produces toxic harmful rotten gas contamination surrounding enviroment such as a large amount of hydrogen sulfide, methane.Therefore need find a new treatment process that wet mud is fully utilized.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, and a kind of directly filtering sewage sludge automatic production process that can effectively handle wet mud and it can be fully utilized is provided.
Another object of the present invention also is to provide a kind of treatment capacity big, the directly filtering sewage sludge automatic production line that treatment effect is good, simple in structure, cost of investment is low.
Another object of the present invention also is to provide a kind of directly filtering sewage sludge automatic production line.
Directly filtering sewage sludge automatic production process of the present invention, its step is as follows: add reodorant, defoamer in mud, then utilize slush pump will pump into the automatic filtering equipment of mud through the mud behind deodorizing and the froth breaking, the dried mud of handling through the automatic filtering equipment of mud is delivered to the resource utilization workshop by handling equipment and processes, and the drainage that is produced then enters in the drainage reclaiming clean pond and handles.
Directly filtering sewage sludge automatic production process of the present invention can directly be filtered mud (or mud) the whole resource utilizations of dry doubling, can realize cancelling sludge landfill.And also have and adapt to widely, all kinds of mud Dujiangyan City is suitable for, and is particularly useful for mud or mud filter that water ratio reaches 80-96% and does.
The automatic filtering equipment of described mud is the automatic filtering equipment of vertical mud.
