Abstract
The invention relates to the technical field of treatment and recycling utilization of animal slaughter industrial wastewater, in particular to the field of sewage treatment of wastewater during blood processing, discloses a method for processing the blood wastewater into reclaimed water through chemical treatment, and finds out a new approach of blood wastewater recycling utilization.
Description
Technical field:
The present invention relates to the improvement and the recycle utilization field of animal slaughtering trade effluent, be specifically related to the pollution treatment processing and the recycle of the waste water of blood course of processing generation.Specifically, be with blood wastewater water and recycle in chemical treating process is made.
Background technology:
Raising along with people's living standard, the consumption of meat is improving day by day, the industrial scale of animal slaughtering industry is also in continuous expansion, the animal blood amount of Chan Shenging also increases day by day thereupon, the enterprise of competitive bidding processing blood in the blood course of processing, can produce a large amount of waste water also increasing, this waste water mainly comes from equipment, processing place flushing etc., wherein contains hemocyte, plasma proteins, glycoprotein, antithrombotics etc.This waste water is red sauce, and SS reaches more than the 800mg/L, and more than the ammonia nitrogen 800mg/L, COD reaches more than the 10000mg/L, basic unharmful substance.The producer that has handles with the SBR method, because the high effect of its processing cost is undesirable again, has become the bottleneck that enterprise produces.At present, some waste water is discharged into rivers silently, and the stench of death flavor because it is unprocessed, is sent in the direct pouring farmland that has after the blood ingredient corruption, cause serious environmental to pollute and extremely bad social influence, and therefore, this waste water rational exploitation and utilization is extremely urgent.Up to the present, domestic research about this respect yet there are no report.
Summary of the invention:
The objective of the invention is to: the method that provides a kind of cheapness simply blood wastewater to be processed into middle water, thus solving the pollution problem of blood wastewater to environment, all right recycle of water is in the blood products processing in this.
The objective of the invention is to realize by following technical scheme:
A kind of treatment process of blood wastewater is characterized in that being processed into middle water with blood is useless.
Concrete steps are as follows:
Blood wastewater is driven in the reaction unit, adds alkali, as milk of lime (calcium hydroxide), yellow soda ash, ammoniacal liquor water soluble alkali, regulate PH at 9-12, be heated to 40 ℃-100 ℃, add acid (as phosphoric acid, sulfuric acid, oxalic acid etc.), consumption is as the criterion to regulate PH6-9.5, stirs; Standing demix; Supernatant liquor told be middle water.The lower sediment thing is mainly the huge legendary turtle compound of albumen and salt, and is recyclable as forage component.
Handle the middle water of back gained: colourless, transparent, tasteless, below the COD500mg/L, below the SS50mg/L, below the ammonia nitrogen 15mg/L, PH6-9 can be recycled.
The present invention has following positively effect:
1, it is high and to the pollution problem of environment to the invention solves the blood wastewater processing cost, provides possibility for manufacturing enterprise realizes " cleaner production ", meets the strategy of sustainable development.
2, the present invention has developed the purposes of blood wastewater, makes trade waste obtain recycle, and water saving meets the recycling economy strategy.
3, process technology equipment provided by the invention is simple, technological process is quick, and is with low cost, is fit to industrialized production.
