Eventually, The attributes of activated sludge become worse and the backflow is too high by 6%.
Differences in location, physical structure, Meteorological growing conditions, And garbage composition of different regions will cause variations in the quality and quantity of leachate.
for this reason, It is not possible to use hard suits during operation. it is vital to adapt to local conditions and adopt appropriate local environment calculation methods.
(that they Yuchuan) 299,14,46 Sewage medicine project network 1. types of waste infiltration liquid The waste infiltration liquid mainly comes from two aspects, particularly, landfill and waste incineration power plant.
The corresponding generating principles are listed below: (1) In the land fill, The garbage itself contains humidity, along with the rain, Snow and also of water that enters the landfill, Deduct the saturated water holding capacity of the garbage and the overburden, And go through the garbage layer and A high-content level wastewater formed by covering the soil layer. (2) Waste incineration power vegetation. The typical properties of domestic waste are high food waste, high water content, High organic variation, Mixed arrangement, And relatively low calorific value. 1 Instruments and reagents Ultra top rated Liquid Chromatography Tandem Mass Spectrometer 2777CACQYITYUPLCXevoTMTQMSWaters Inc. you.S.

2. The CODcr and BOD5 power of high leachate can be as high as 90,000 mg / L, 38000 mg / L and higher.

so,that being said, In the design of the household waste incineration plant, The storage capacity of the garbage pit is 37 times the daily payment capacity of the garbage (this is, The house time is 37 days), it's, The garbage is stored in the garbage pit after 37 days of fermentation and readiness. the river leached from the garbage is called permeate.
2. composition of garbage infiltration liquid The GCMS combined technology was used to analyze the arrangement of organic pollutants in the garbage infiltration liquid, And 63 kinds of main organic impurities in the garbage infiltration liquid were detected.
particularly, you will 6 kinds of alkanes, 19 kinds carboxylic acids, 5 styles of esters, 10 strains of alcohols and phenols, 10 kinds aldehydes and ketones, 7 possible kinds, 1 kind of savoury hydrocarbons, And 5 types of others. 2 The pH changes and the generation of SO42 in the entire denitrification The problem of acid production and by-Product SO42 often exists with low-Valent sulfur beeing the electron donor for denitrification
such as, 6 species have been identified as one kind of cause substance, 4 kinds of stimulant and auxiliary cause ingredient, And 1 fairly mutagen. They are listed in the “black list” of the environmental priority pollutants in China.
great value CODcr and BOD5 in the permeate can reach 90000mg / L, 38000mg / L or even a higher.
And it increases with the extension of landfill time, significantly 1700mg / L.
The nitrogen in the permeate is mostly like ammonia nitrogen, construction for about 40% and 50% of TNK.
accountant los angeles than ten kinds of metal ions in the waste permeate, which iron and zinc are higher in the acid fermentation stage, The concentration of iron can reach about 2000mg / L, The concentration of zinc can reach about 130mg / L, And the concentration of lead can reach 12. after denitrify
(3) vegetable salty pickling wastewater is high-sodium wastewater, Which is much higher than the tolerance of activated sludge. If activated sludge aeration method used, very first wastewater must be diluted before treatment. The salt in water cannot be degraded, ensuing a raw salt And serious waste of water resources.

3mg / m, The calcium awareness even reached 4300mg / L1.
6 The imbalance of the portion of microbial nutrients in the permeate is mainly the imbalance of C, N combined with P.
3. Water quality fluctuations of garbage permeate as per the age of the landfill, The waste permeate is split into two types. The first type is young permeate with a landfill time of not quite 5 years. It is characterized by high power of CODcr and BOD5 and biodegradability. robust, The other is aged permeate with a landfill time of more than 5 years. As fresh waste gradually over time becomes obsolete, Its pH is around neutral, The power of CODcr and BOD5 is reduced, And the ratio of BOD5 / CODcr is reduced. The ammonia nitrogen actions increases. 7 What are the characteristics of food industry wastewater pollution and what are its treatment protocols?

As long as your handmade jewelry is in place of certificate anti-Counterfeiting, i know of no need to specifically make the watch hardcover box factory to do such beautiful packaging. How packaging almost certainly give consumers e-Commerce success and ruin the wrist watch hardcover factory.
The cover film is the smoother and brighter light of the transparent plastic film applied to the surface of the printed product by hot pressing, And the visuals and text are more colorful, And it also plays a role in waterproofing and antifouling. It can be put into two parts: Surface dealing and molding digesting. Processing concept; Molding processing advancement. The coating makes the look off the printed matter wear-resistant, flip the-resilient and chemical-unwilling. to the, since the plastic film is not degradable, it is sometimes complicated to withdraw and use, And you can actually constitute pollution. thusly, Plastic coating process should be used with caution when glazing can be replaced. 1 handle.
Newsprint is mainly used in the printing of newspapers or some letterpress books and newspapers. The document is soft, bendable, Strong in ink levels, And has a certain hardware strength. It can be best with printing on various high-Speed rotary washers. varieties paper contains a lot of lignin impurities, And the paper is easy to yellow and has poor water resistance, So it is not suited to long-Term shelves. Whiteboard paper is a term paper with a relatively uniform fiber structure. The surface layer has a rubber filler component and a layer of paint on the surface. A paper made by multi-Roll calendering has a high color purity and good folding resistance. magnitude, Uniform ink inclusion, Mainly used in picture and wall chart products or services table lining gifts boxes and so on.
The integrity of Hebei's customized cosmetic packaging box suppliers is guaranteed. With the increase of environment awareness, People are increasingly concerned about the importance of the habitat for health. Under these types of thinking, Many gift box packaging designers choose to integrate green and the environmental protection concepts into the gift box packaging design, So that the general gift box packaging is full of natural air, Which not only delights the buyer's mood, But also a good Space maintenance.
