公司簡(jiǎn)介:濟(jì)寧天通水處理設(shè)備有限公司位于山東省濟(jì)寧市。其核心產(chǎn)品有:污水處理站、廢水處理工藝、廢水處理設(shè)備、工業(yè)廢水處理設(shè)備、水處理設(shè)備、生活污水處理設(shè)備、環(huán)境污水處理設(shè)備等設(shè)備。歲月流逝,一支年輕充滿朝氣的團(tuán)隊(duì)充滿了技術(shù)、環(huán)境工程經(jīng)驗(yàn),與多家大型、高要求的公司保持著同樣的藍(lán)天,創(chuàng)造了“綠色澤”的宗旨,堅(jiān)持“客戶*一,質(zhì)量*一”的服務(wù)宗旨,客戶滿意是我們永恒的追求。在實(shí)踐中,要不斷提高技術(shù)水平,完善內(nèi)部管理,完善組織和售后跟蹤服務(wù),力爭(zhēng)以較快捷、較方便的方式為顧客提供熱枕服務(wù)。
皮革廢水處理成套設(shè)備
皮革廢水主要來(lái)源于鞣前準(zhǔn)備,鞣制和其他濕加工工段。
污染較重的是脫脂廢水、浸灰脫毛廢水、鉻鞣廢水.制革廢水的特點(diǎn)表現(xiàn)在以下幾方面懸浮物濃度高,易腐敗,產(chǎn)生污染量大;水質(zhì)水量波動(dòng)大;可生化性好;廢水含S2-和鉻等有毒化合物。皮革廢水的處理方法也很多,有生化工藝和物化等方法。國(guó)內(nèi)制革工業(yè)皮革污水處理通常采用物化處理離心機(jī)分離和生化處理相結(jié)合的方法,此法投資省,運(yùn)行費(fèi)用低,能夠穩(wěn)定達(dá)標(biāo)排放。
制革業(yè)是產(chǎn)生大量污水的行業(yè),制革污水不僅量大,而且是一種成分復(fù)雜、高濃度的有機(jī)廢水,由于制革生產(chǎn)中使用了大量的脫脂劑、加脂劑和表面活性劑,生化處理難度也很大。
處理工藝不合理、運(yùn)行費(fèi)用太高(處理水越多,企業(yè)背的包袱越大)、運(yùn)行管理麻煩,而不能正常運(yùn)行,有一定數(shù)量的制革廠廢水未經(jīng)處理或只經(jīng)過(guò)簡(jiǎn)單沉淀后直接排入河流或湖泊,有的甚至滲坑排放。
制革污泥還可進(jìn)行厭氧發(fā)酵處理,進(jìn)行沼氣能源回收,經(jīng)厭氧發(fā)酵后的制革污泥,但是前期要進(jìn)行一些重金屬方面的處理,又是非常好的農(nóng)用肥料,用在農(nóng)田中,可以防止土地板結(jié);也可以加入桔桿直接發(fā)酵,用作農(nóng)肥。
皮革制革污泥特點(diǎn):產(chǎn)泥量大,廢水量也很大。有機(jī)物含量高,由于在皮革處理過(guò)程中產(chǎn)生大量的皮毛、血污,所以有機(jī)物含量非常高。
皮革廢水處理是水處理工程中投資和維護(hù)費(fèi)用較高的部分,因此正確選擇污泥脫水工藝十分重要,要選擇臥式離心機(jī)這種處理能力強(qiáng)的設(shè)備。
機(jī)器的選型可以選不銹鋼材料的多種選擇如304,316L,321,雙相不銹鋼等,或依據(jù)客戶要求訂制。所有與物料接觸的部件均由優(yōu)質(zhì)不銹鋼制成,可滿足客戶的制定要求。

Complete set of equipment for treating leather waste water
Leather wastewater is mainly derived from pre tanning preparation, tanning and other wet processing sections.
The most serious pollution is defatted wastewater, liming wastewater and chrome tanning wastewater. The characteristics of tannery wastewater are the following aspects: high suspended solids concentration, easily spoilage, large amount of pollution, large fluctuation of water quality and quantity, good biodegradability, wastewater containing S2- and chromium and other toxic compounds. There are many methods for treating leather waste water, including biochemical technology and physicochemical methods. The tannery industry leather wastewater treatment usually combines physicochemical treatment with centrifuge separation and biochemical treatment. This method has low investment and low operation cost, and can achieve stable discharge.
Tanning industry is the industry that produces a lot of *age. Tannery wastewater is not only large, but also a complex and high concentration organic wastewater. Because of a lot of degreasing agents, fatliquoring agents and surfactants in leather making, biochemical treatment is also very difficult.
Treatment is not reasonable, the operation cost is too high (with more water companies back more baggage), the operation and management of trouble, and not the normal operation, there is a certain number of tannery wastewater untreated or directly into the simple after precipitation of rivers or lakes, some even pit seepage discharge.
Tannery sludge can also be treated by anaerobic fermentation, biogas for energy recovery, the tannery sludge by anaerobic fermentation, but early to deal with some heavy metals, and agricultural fertilizer is very good, used in farmland, can prevent hardening of the soil; can also add straw direct fermentation, used as fertilizer.
The characteristics of leather tannery sludge: large amount of mud and large amount of waste water. The content of organic matter is high, due to a large amount of fur, blood in the treatment of leather, so very high content of organic matter.
Leather wastewater treatment is a part of investment and maintenance cost in water treatment project. Therefore, it is very important to choose sludge dewatering technology correctly. We must choose horizontal centrifuge as a powerful processing equipment.
The selection of the machine can be selected for a variety of stainless steel materials such as 304316L, 321, duplex stainless steel, etc., or customized according to the requirements of the customer. All the parts in contact with the material are made of high quality stainless steel, which can meet the requirements of the customers.
