Description

Raw tomatoes material purging system end water treatment technology adopted by a kind of machine
Technical field
The present invention relates to Fructus Lycopersici esculenti and clean raw material sewage disposal, particularly a kind of machine is adopted at raw tomatoes material purging system end water Science and engineering skill.
Background technology
At present, for the processing method of Fructus Lycopersici esculenti rinse water, mainly have following several:
The first: directly discharge.This kind of method is by the most treated for the rinse water of raw tomatoes material direct discharge, but due to clearly Containing a large amount of silts, weeds, a small amount of soluble sugar, tomato pulp and pectin in wash water, can be to environment after fermentable Produce harmful effect.The second: discharge after Sewage Disposal processes.Current most of Tomato Processing Enterprises uses this kind of side Method.Sewage in tomato product production process mostlys come from the waste water cleaning Fructus Lycopersici esculenti, and it cleans Fructus Lycopersici esculenti without poisonous and harmful substance Water in be usually mixed with discarded decayed fruit and skin slag, need to carry out pretreatment.But due to the instability of raw materials quality, cause sewage Water quality often changes, and brings certain difficulty to sewage disposal.Fructus Lycopersici esculenti wastewater processing technology is through groping for many years, put into practice, always both at home and abroad Bear Fructus Lycopersici esculenti waste water through materialization, biochemical processing process, can qualified discharge after process.Before the nineties, domestic biochemical treatment is many For traditional activated sludge process.After the nineties, the advanced technologies such as bio-contact oxidation, two-stage oxidizing, CASS, HCR introduces Fructus Lycopersici esculenti During wastewater biochemical processes, make Fructus Lycopersici esculenti waste water treatment efficiency this kind of sewage water treatment method technical difficulty that be greatly improved relatively big, right The requirement of equipment and technique is high, builds and runs costly.The third: use concentrator to carry out physical separation.Concentrator It is mainly used in leachate and concentrates the technique needing solid-liquor separation with waste water process etc..Compared with common concentrator, Hhigh-efficient thickener Having obvious advantage, its floor space is little, consumes power and fragile part is few, and disposal ability is big, and thickening efficiency is high, and it increases Big ratio of height to diameter makes the time of staying that particulate ore pulp is necessary in machine, go deep into sedimentary feeds more ensure that particulate be deposited Layer catches, the application of high polymer coagulant enhances ore pulp flocculating result, thus output more clear overflow water and the richer end Stream.This kind of method is relatively suitable for machine from principle, and to adopt Fructus Lycopersici esculenti cleaning sullage sediment charge big, the content of organic matter is many, not free settling Feature.Meanwhile, major part the clear water of generation cannot be carried out again with, easily cause waste, add the cost of enterprise.
Summary of the invention
The invention aims to solve the problems referred to above, devise a kind of machine and adopt at raw tomatoes material purging system end water Science and engineering skill.
Realizing above-mentioned purpose the technical scheme is that, science and engineering at raw tomatoes material purging system end water adopted by a kind of machine Skill, comprises the steps:
