Abstract

The invention discloses a method for preparing mixed fertilizer with sludge from wastewater treatment plant. In the method, sludge and cow dung are mixed well in a proportion of 1:1 to 1:2 for composting. Wherein, in terms of the size of a compost, the upper opening surface is 25*10*3m, and the proportion of edge to slope is 1:1; the temperature of the compost is over 50DEG C; the moisture is controlled in a range of 20-30%; the pH is controlled at a level of 7.2-7.8; and the time of composting is 15 days. The method of the invention has the advantages of simple operation method and small investment. If 16 million tons of sludge are disposed annually, more than 0.2 million tons of nitrogen, 0.16 million tons of phosphor and potassium can be obtained each year. Containing multiple types of trace elements, the sludge in wastewater is a total nutrient organic/inorganic composite fertilizer. Over two years of tests demonstrate that, the fertilizer prepared with the method of the invention has good effects on crop output and quality, thus having high development and utilization value.

Description

A kind of sewage-farm mud that utilizes prepares the method for mixing fertilizer
Technical field
The present invention relates to a kind of fertile method of sewage-farm mud preparation mixing of utilizing.
Background technology
The municipal sewage plant all can produce a large amount of mud every year, and along with the raising of wastewater treatment rate and degree of treatment, the output of this class mud also will be increasing from now on.Because for these mud have stink and contain a large amount of pathogenic bacterias, parasitic ovum and weed seed.Can not carry out appropriate harmless treatment as it, just can cause very big pollution to atmosphere, water and soil earth easily.Because plant nutrient ingredient nitrogen, phosphorus, potassium content in these mud all are quite abundant, if it can be developed as the source of manure, not only can eliminate its pollution to environment, can also produce great economic benefit.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of sewage-farm mud that utilizes to prepare the method for mixing fertilizer.
Technical scheme proposed by the invention is: mud and cow dung are evenly carried out compost by 1: 1 to 1: 2 mixed.Fertile heap is of a size of: go up open area 25 * 10 * 3m, side slope was than 1: 1.Compost temperature＞50 ℃, moisture controlled is at 20--30%, and pH is controlled at 7.2-7.8; The compost fate is 15 days.
Leading indicator requires behind the compost:
Colititre: 10 2～10 3Individual/kg; Roundworm egg: 6/kg; Roundworm mortality ratio: 95.9%;
Moisture: 20% pH7.8 organic matter: 17.5～19.0% NO3-N:5.35%
NH3-N:0.23% rapid available phosphorus: 1.89% available potassium: 42.5%
Advantage of the present invention is that working method is simple, and is convenient and practical, also do not need great expense investment.In 1,600 ten thousand tons of mud of year processing and utilizing, annual can obtain 20 approximately surplus ten thousand tons of nitrogen, 160,000 tons of phosphorus and potassium.Also containing various trace elements in the sewage sludge, is the organic/inorganic composite fertilizer of full nutrition, confirms through the test more than 2 years, and the fertilizer that utilizes this method preparation all has good action to the yield and quality of crop, and its value of exploiting and utilizing is very high.
Specific embodiment
Example 1
Technical scheme proposed by the invention is: mud and cow dung are evenly carried out compost by 1: 1 mixed.Fertile heap is of a size of: go up open area 25 * 10 * 3m, side slope was than 1: 1.Compost temperature＞50 ℃, moisture controlled is 20%, and pH is controlled at 7.8; The compost fate is 15 days.
Example 2
Below be testing data of the present invention:
Harmful organism is killed situation before and after the table 1 sewage sludge composting
