Description

A kind of pesticide integrated waste water treatment method
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of pesticide integrated waste water treatment method.
Background technology
In recent years, along with socioeconomic fast development, the ecological environment of China is subject to increasingly severe destruction, and the destruction of environment is increasingly sharpened by the daily production activity of the mankind.More ammonia nitrogen and CODcr is discharged in particular from the wastewater from chemical industry producing the industry such as chemical fertilizer, food, iron and steel, the excessive entrance water body environment of this type of high pollution waste water, the ecosystem that water environment is intrinsic can be destroyed, the growing environment making aqueous bio is damaged, and can cause that the eutrophication of water body increases the weight of day by day.Data according to ASSOCIATE STATISTICS department of Chinese Ministry of Environmental Protection shows, the river of China, section pollute quite serious, has the water body of 25% all to cannot be used for irrigation, the economic development of this safe drinking water having a strong impact on we people and society because of seriously polluted；The whole nation has more than the waters of half and occurs in that serious eutrophication, and freshwater lake as main in Dian Chi, Poyang Lake, Taihu Lake etc. pollutes just very serious, and water field of big area all occurs in that eutrophication, the basic function losing water body having.In order to make the Ecoenvironment and social economy of China develop in harmony, China must formulate stricter integrated wastewater discharge standard and special industry wastewater discharge standard, and the therefore more efficient and economic each pollutant contained in waste water of removing has become as focus and the difficulties of water treatment field.
Pesticide wastewater mostlys come from production process concentrating under reduced pressure, filtration, waste gas treatment process, CODcr, BOD5 in waste water, ammonia-nitrogen content is higher, biodegradability is poor, have strong impulse abnormal smells from the patient, general wastewater treatment measure is adopted to be difficult to waste water is made directly process, therefore, in view of these problems, pesticide wastewater can thoroughly be processed by research one, make waste water discharge index and reach the pesticide integrated waste water treatment method of the requirement in integrated wastewater discharge standard, have important practical significance.
Summary of the invention
It is an object of the invention to the deficiency existed for prior art, it is provided that pesticide wastewater can thoroughly be processed by one, make waste water discharge index and reach the pesticide integrated waste water treatment method of the requirement in integrated wastewater discharge standard.
The technical scheme is that a kind of pesticide integrated waste water treatment method, process step and include following:
(1) by physical and chemical parameter it is: pH:8～9, SS=150mg/L, COD:5000mg/L, NH3The pesticide comprehensive wastewater of-N=150mg/L and compressed air import in airfloat equipment, air is made to be dissolved in water and become small bubble, form dissolved air water, in airfloat equipment, dissolved air water is released by the reduction of release pressure, at normal temperatures and pressures, it is dissolved in the air in water just to overflow from water, form the mixed system of air, waste water, in the basic conditions, the dynamic equilibrium between molecular state NH3 and ionic state NH4+ is moved to the direction generating NH3, now with air bubble for carrier, NH3, through gas-liquid interface, is gradually diffused in air；
(2) the pesticide comprehensive wastewater after step (1) processes is collected in the first liquid storage tank, be filled with air, make waste water be sufficiently mixed, with elevator pump, the waste water in liquid storage tank is squeezed into oxidation pond, in oxidation pond, add H2O2、FeSO4, hydrochloric acid, and it is filled with air, so as to fully react, Calx, PAC, PAM is added after having reacted, make the iron ion in waste water and ferrous ion flocculation sediment, the mud screw pump that flocculation sediment produces squeezes into sludge dewatering equipment, and waste water is partially into the second liquid storage tank through filtering ponds, is partially into the first liquid storage tank and continues cycling through process；
(3) in the second liquid storage tank, add cooling water and the sanitary sewage of 800t/d, and supplementary nitrogenous source, phosphorus source, it is filled with air, waste water is made to be sufficiently mixed, with elevator pump, the waste water in liquid storage tank being squeezed into hydrolysis acidification pool, in hydrolysis acidification pool, difficult degradation larger molecular organics can be decomposed into degradable small organic molecule by the microorganism in waste water, waste water after hydrolysis acidification flows into sedimentation tank to reduce the SS concentration in waste water, with pump, the waste water after precipitation is squeezed into BIOFOR biofilter；
(4) sending into hypochlorite oxidation pond through the waste water after step (3) processes, and regulate wastewater pH 7～8, put into sodium hypochlorite, the response time is 0.5～2h, and wastewater treatment system is stirred, and reacted waste water is sent into clear water reserviors.
Further, the alr mode in described step (4), wastewater treatment system being stirred is aeration agitation or mechanical agitation.
The beneficial effects of the present invention is:
The waste water of the present invention discharges index: pH=6-9, CODcr=80mg/L, BOD5=5mg/L, SS=10mg/L, ammonia nitrogen concentration reduces to 0.1mg/L, and ammonia nitrogen removal frank is up to 99.8%, the ammonia nitrogen concentration of water outlet meets the primary standard in " integrated wastewater discharge standard " (GB8978-1996), it is possible to effective and economical removes each pollutant contained in waste water.
Detailed description of the invention
Below the specific embodiment of the present invention is made brief description.
