Abstract
The invention provides a method for producing humate from base waste liquid. The method comprises the following processes: collecting soluble-base-containing wastewater generated in a base factory or saline solution electrolysis process, airing and concentrating to obtain base waste liquid with a base concentration of 18-22%; processing weathered coal or lignite or peat into coal powder by using a pulverizer, mixing the coal powder and the base waste liquid according to a weight ratio of 1:(8-10) and adding the mixture to a reaction kettle, uniformly stirring, heating, standing and precipitating, and thus obtaining the reaction precipitate and reaction supernatant after the reaction materials in the reaction kettle are still and precipitate; adding hydrochloric acid solution to the reaction supernatant, and drying the supernatant precipitate to obtain a finished product; and placing the reaction precipitate to a precipitating pond, uniformly mixing the reaction precipitate and humic acid according to a weight ratio of reaction precipitate to humic acid being 1:(0.5-0.8), standing for 2-3 hours, and spraying and granulating the mixed material to obtain a finished product used as fertilizer. The method has the advantages that wastewater can be recycled, environmental pollution is avoided, the process is simple and practical, the extraction cost is low, therefore, the method can be popularized and used.
Description
Technical field
The invention belongs to the environmental friendly regenerated technical field of utilizing of trade effluent, relate to the method that a kind of alkali wasteliquid is produced humate.
Background technology
China is large agricultural country, the chemical fertilizer of annual labor, but the raising the output of the increase of chemical fertilizer usage quantity and farm crop is disproportionate; The often increase of chemical fertilizer usage quantity; Cause the hardening soil on the contrary, the decline of crop yield, this is because chemical fertilizer utilization ratio is low, fertilizer efficiency descends.Be merely about 35% according to side examination China chemical fertilizer utilization ratio, be lower than 55% of developed country.Humate and goods thereof have multiple use.Agriculturally, humic acids salt series fertilizer (Sodium salts humic acids, potassium humate, ammonium humate etc.) can be improved mid and low yield soils, the getting fat high production soil, and fertilizer efficiency is long.Utilization ratio is high, improves the soil rational performance, has low cost, full nutrition, long-acting type and anti-pollution, characteristics such as the ecotype.In industrial aspect, Sodium salts humic acids is used for ceramic material adjustment, low pressure boiler; The locomotive boiler antiscale, sulfonated humic acid sodium is used for cement water reducing agent, and the humic acids goods are also as the oil drilling slurry treatment agent; In addition, Sodium salts humic acids also is widely used in briquetting, foundry sand sticker etc.Humic acids is a kind of natural organic high molecular compound, is that a kind of multi-functional chemical materials has wide industrial and agricultural use, is used for aspects such as forestry, animal husbandry and medicine in a large number.Traditional humate process for extracting is comparatively complicated, and extraction yield is low, and extraction cost is high, and extraction rate is slow, contaminate environment.On the other hand, can produce a large amount of alkali waste waters that contains,, contain alkali waste water and enter contaminate environment in the rivers like the waste water that contains water soluble alkali that produces in alkali factory or the electrolytic saltwater process at the Industrial processes product.
Summary of the invention
The purpose of this invention is to provide a kind of method of producing humate, make it have the waste water reclamation utilization with alkali wasteliquid, free from environmental pollution, features simple and practical process, the advantage that extraction cost is low.For this reason, a kind of method of producing humate with alkali wasteliquid, it is to be made up of following technological process:
(1), collect the waste water that contains water soluble alkali that is produced in alkali factory or the electrolytic saltwater process, the cool solarization concentrates, and processes the alkali wasteliquid that contains alkali concn 18～22%;
(2), with weathered coal, or brown coal, or mud coal joins in the kibbler, is broken into the particle that granularity is 0.2～0.5mm, processes coal dust;
(3), press coal dust: the raw material weight proportioning of alkali wasteliquid=1: 8～10; Above-mentioned raw materials is mixed to join in the reaction kettle, stirs, begin to be heated to 89 ℃～91 ℃; Heat and stop heating after 1～1.5 hour; Staticly settle, after the reactant static layering in the question response still, get reaction precipitation thing and reaction supernatant;
(4), negate answers supernatant, in the reaction supernatant, slowly adds hydrochloric acid soln, mixes, and reduces to 2 until the pH value of this supernatant, staticly settles 8～12 hours, gets this supernatant throw out oven dry, finished product;
(5), negate answers throw out, places settling tank, presses the reaction precipitation thing: the raw material weight proportioning of humic acids=1: 0.5～0.8, above-mentioned raw materials is mixed, left standstill 2～3 hours, compound is carried out spray granulating, must can be used as the finished product of fertilizer.The waste water of described water soluble alkali is the waste water that contains sodium hydroxide or Pottasium Hydroxide or hydrated barta.Aforesaid method has been realized the object of the invention.
Advantage of the present invention is the waste water reclamation utilization, and is free from environmental pollution, reduced effluent charge usefulness significantly, and it is simple and practical also to have method, and extraction cost is low, only is 70% of traditional method cost.Do not have the wasting of resources in the leaching process of the present invention, production process does not produce solid waste, and reactant all has utilization, increases resource utilization.
Embodiment
The present invention adopts enamel reaction still, vertical response pot all can.Described dryer is a roller dryer, and dryer is bought or self-control all can.
Embodiment 1: a kind of method of producing humate with alkali wasteliquid, and it is to be made up of following technological process to collect the waste water that contains water soluble alkali that is produced in alkali factory or the electrolytic saltwater process, the cool solarization concentrates, and processes the alkali wasteliquid that contains alkali concn 18～22%; With weathered coal, or brown coal, or mud coal joins in the kibbler, is broken into the particle that granularity is 0.2～0.5mm, processes coal dust; Press coal dust: the raw material weight proportioning of alkali wasteliquid=1: 8～10; Above-mentioned raw materials is mixed to join in the reaction kettle, stirs, begin to be heated to 89 ℃～91 ℃; Heat and stop heating after 1～1.5 hour; Staticly settle, after the reactant static layering in the question response still, get reaction precipitation thing and reaction supernatant; Supernatant is answered in negate, in the reaction supernatant, slowly adds hydrochloric acid soln, mixes, and reduces to 2 until the pH value of this supernatant, staticly settles 8～12 hours, gets the throw out oven dry of this supernatant, gets finished product.Throw out is answered in negate, places settling tank, presses the reaction precipitation thing: the raw material weight proportioning of humic acids=1: 0.5～0.8, above-mentioned raw materials is mixed, and left standstill 2～3 hours, compound is carried out spray granulating, must can be used as the finished product of fertilizer.
